10 grmlzshrc - Grml's zsh setup
14 //zsh// [**options**]...
18 The Grml project provides a fairly exhaustive interactive setup (referred to
19 as //grmlzshrc// throughout this document) for the amazing unix shell zsh
20 (http://zsh.sourceforge.net). This is the reference manual for that
23 To use //grmlzshrc//, you need at least version 3.1.7 of zsh (although not all
24 features are enabled in every version).
26 //grmlzshrc// behaves differently depending on which user loads it. For the
27 root user (**EUID** == 0) only a subset of features is loaded by default. This
28 behaviour can be altered by setting the **GRML_ALWAYS_LOAD_ALL** STARTUP
31 Users may want to keep an up-to-date version of the setup (possibly from the
32 git-sources) in //~/.zshrc//. If that happens on a system where the global
33 zshrc is also a //grmlzshrc// (but possibly an older one), you can inhibit
34 loading the global version by doing:
37 echo setopt no_global_rcs >> ~/.zshenv
40 Note, that this will disable //ANY// global files, except for the global
44 Some of the behaviour of //grmlzshrc// can be altered by setting certain shell
45 variables. These may be set temporarily when starting zsh like this:
49 Or by setting them permanently in **zshrc.pre** (See AUXILIARY FILES below).
52 If set to a value greater than zero and //acpi// installed, //grmlzshrc// will
53 put the battery status into the right hand side interactive prompt.
55 : **COMMAND_NOT_FOUND**
56 A non zero value activates a handler, which is called when a command can not
57 be found. The handler is defined by GRML_ZSH_CNF_HANDLER (see below).
59 : **GRML_ALWAYS_LOAD_ALL**
60 Enables the whole Grml setup for root, if set to a non zero value.
62 : **GRML_ZSH_CNF_HANDLER**
63 This variable contains the handler to be used by COMMAND_NOT_FOUND (see above)
64 and defaults to "/usr/share/command-not-found/command-not-found".
66 : **GRMLSMALL_SPECIFIC**
67 Set this to zero to remove items in zsh config, which do not work in
71 Where zsh saves the history. Default: ${HOME}/.zsh_history.
74 Number of commands to be kept in the history. On a Grml-CD this defaults to
75 500, on a hard disk installation to 5000.
78 Sets the frequency in seconds for zsh to check for new mail. Defaults to 30.
79 A value of zero turns off checking.
82 Non zero values deactivate automatic correction of commands.
85 If set to zero (default), allows selection from a menu, if there are at least
86 five possible options of completion.
89 A non zero value disables precmd and preexec commands. These are functions
90 that are run before every command (setting xterm/screen titles etc.).
93 Show time (user, system and cpu) used by external commands, if they run longer
94 than the defined number of seconds (default: 5).
97 Number of commands to be stored in ${HISTFILE}. Defaults to 1000 on a Grml-CD
98 and to 10000 on an installation on hard disk.
101 As in tcsh(1) an array of login/logout events to be reported by the shell
102 builtin "log". For details see zshparam(1). Defaults to (notme root).
104 : **ZSH_NO_DEFAULT_LOCALE**
105 Import "/etc/default/locale", if set to zero (default).
108 A non zero value causes shell functions to be profiled. The results can be
109 obtained with the zprof builtin command (see zshmodules(1) for details).
112 = FEATURE DESCRIPTION =
113 This is an in depth description of non-standard features implemented by
116 == DIRSTACK HANDLING ==
117 The dirstack in //grmlzshrc// has a persistent nature. It is stored into a
118 file each time zsh's working directory is changed. That file can be configured
119 via the **DIRSTACKFILE** variable and it defaults to **~/.zdirs**. The
120 **DIRSTACKSIZE** variable defaults to **20** in this setup.
122 The **DIRSTACKFILE** is loaded each time zsh starts, therefore freshly started
123 zshs inherit the dirstack of the zsh that most recently updated
126 == DIRECTORY BASED PROFILES ==
127 If you want certain settings to be active in certain directories (and
128 automatically switch back and forth between them), this is what you want.
131 zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)' profile grml
132 zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
135 When that's done and you enter a directory that matches the pattern
136 in the third part of the context, a function called chpwd_profile_grml,
137 for example, is called (if it exists).
139 If no pattern matches (read: no profile is detected) the profile is
140 set to 'default', which means chpwd_profile_default is attempted to
143 A word about the context (the ':chpwd:profiles:*' stuff in the zstyle
144 command) which is used: The third part in the context is matched against
145 **$PWD**. That's why using a pattern such as /foo/bar(|/|/*) makes sense.
146 Because that way the profile is detected for all these values of **$PWD**:
154 So, if you want to make double damn sure a profile works in /foo/bar
155 and everywhere deeper in that tree, just use (|/|/*) and be happy.
157 The name of the detected profile will be available in a variable called
158 'profile' in your functions. You don't need to do anything, it'll just
161 Then there is the parameter **$CHPWD_PROFILE** which is set to the profile,
162 that was active up to now. That way you can avoid running code for a
163 profile that is already active, by running code such as the following
164 at the start of your function:
167 function chpwd_profile_grml() {
168 [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
173 The initial value for **$CHPWD_PROFILE** is 'default'.
175 === Signaling availabily/profile changes ===
177 If you use this feature and need to know whether it is active in your
178 current shell, there are several ways to do that. Here are two simple
181 a) If knowing if the profiles feature is active when zsh starts is
182 good enough for you, you can put the following snippet into your
186 (( ${+functions[chpwd_profiles]} )) &&
187 print "directory profiles active"
190 b) If that is not good enough, and you would prefer to be notified
191 whenever a profile changes, you can solve that by making sure you
192 start **every** profile function you create like this:
195 function chpwd_profile_myprofilename() {
196 [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
197 print "chpwd(): Switching to profile: $profile"
202 That makes sure you only get notified if a profile is **changed**,
203 not everytime you change directory.
205 === Version requirement ===
206 This feature requires zsh //4.3.3// or newer.
209 == ACCEPTLINE WRAPPER ==
210 The //accept-line// wiget is the one that is taking action when the **return**
211 key is hit. //grmlzshrc// uses a wrapper around that widget, which adds new
214 This wrapper is configured via styles. That means, you issue commands, that look
218 zstyle 'context' style value
221 The context namespace, that we are using is 'acceptline'. That means, the actual
222 context for your commands look like: **':acceptline:<subcontext>'**.
224 Where **<subcontext>** is one of: **default**, **normal**, **force**, **misc**
228 === Recognized Contexts ===
230 This is the value, the context is initialized with.
231 The //compwarnfmt and //rehash// styles are looked up in this context.
234 If the first word in the command line is either a command, alias, function,
235 builtin or reserved word, you are in this context.
238 This is the context, that is used if you hit enter again, after being warned
239 about the existence of a _completion for the non-existing command you
243 This is the context, you are in if the command line is empty or only
244 consists of whitespace.
247 This context is in effect, if you entered something that does not match any
248 of the above. (e.g.: variable assignments).
251 === Available Styles ===
253 If you set this style to true, the warning about non existent commands,
254 for which completions exist will not be issued. (Default: **false**)
257 The message, that is displayed to warn about the _completion issue.
258 (default: **'%c will not execute and completion %f exists.'**)
259 '%c' is replaced by the command name, '%f' by the completion's name.
262 If this is set, we'll force rehashing, if appropriate. (Defaults to
263 **true** in //grmlzshrc//).
266 This can be a list of wigdets to call in a given context. If you need a
267 specific order for these to be called, name them accordingly. The default value
268 is an **empty list**.
271 The name of a widget, that is called after the widgets from 'actions'.
272 By default, this will be '.accept-line' (which is the built-in accept-line
276 If true in the current context, call the widget in the 'default_action'
277 style. (The default is **true** in all contexts.)
283 == GNU/SCREEN STATUS SETTING ==
284 //grmlzshrc// sets screen's hardstatus lines to the currently running command
285 or **'zsh'** if the shell is idling at its prompt. If the current working
286 directory is inside a repository unter version control, screen status is set
287 to: **'zsh: <repository name>'** via zsh's vcs_info.
290 == PERSISTENT HISTORY ==
291 If you got commands you consider important enough to be included in every
292 shell's history, you can put them into ~/.important_commands and they will be
293 available via the usual history lookup widgets.
297 == ENVIRONMENT VARIABLES ==
298 //grmlzshrc// sets some environment variables, which influence the
299 behaviour of applications.
302 Set to "yes". Some applications read this to learn about properties
303 of the terminal they are running in.
306 If not already set, sets the default editor. Falls back to vi(1),
307 if vim(1) is not available.
310 Some environment variables that add colour support to less(1) for viewing
311 man pages. See termcap(5) for details.
314 The mailbox file for the current user is set to /var/mail/$USER, if not
315 already set otherwise.
318 Set less(1) as default pager, if not already set to something different.
321 Holds the path to shared files for the C++ application framework QT
325 Set explicitly to /bin/zsh, to prevent certain terminal emulators to
326 default to /bin/sh or /bin/bash.
330 Apart from zsh's default options, //grmlzshrc// sets some options
331 that change the behaviour of zsh. Options that change Z-shell's default
332 settings are marked by <grml>. But note, that zsh's defaults vary depending
333 on its emulation mode (csh, ksh, sh, or zsh). For details, see zshoptions(1).
336 Zsh sessions, that use //grmlzshrc//, will append their history list to the
337 history file, rather than replace it. Thus, multiple parallel zsh sessions
338 will all have the new entries from their history lists added to the history
339 file, in the order that they exit. The file will still be periodically
340 re-written to trim it when the number of lines grows 20% beyond the value
341 specified by $SAVEHIST.
344 If a command is issued that can't be executed as a normal command, and the
345 command is the name of a directory, perform the cd command to that directory.
347 : **auto_pushd** <grml>
348 Make cd push the old directory onto the directory stack.
350 : **completeinword** <grml>
351 If the cursor is inside a word, completion is done from both ends;
352 instead of moving the cursor to the end of the word first and starting
355 : **extended_glob** <grml>
356 Treat the '#', '~' and '^' characters as active globbing pattern characters.
358 : **extended_history** <grml>
359 Save each command's beginning timestamp (in seconds since the epoch) and the
360 duration (in seconds) to the history file.
363 Whenever a command completion is attempted, make sure the entire command
364 path is hashed first. This makes the first completion slower.
366 : **histignorealldups** <grml>
367 If a new command line being added to the history list duplicates an
368 older one, the older command is removed from the list, even if it is
369 not the previous event.
371 : **histignorespace** <grml>
372 Remove command lines from the history list when the first character on
373 the line is a space, or when one of the expanded aliases contains a
374 leading space. Note that the command lingers in the internal history
375 until the next command is entered before it vanishes.
377 : **longlistjobs** <grml>
378 List jobs in long format by default.
381 Avoid to beep on errors in zsh command line editing (zle).
384 A wildcard character never matches a leading '.'.
387 Do not send the hangup signal (HUP:1) to running jobs when the shell exits.
389 : **nonomatch** <grml>
390 If a pattern for filename generation has no matches, do not print an error
391 and leave it unchanged in the argument list. This also applies to file
392 expansion of an initial `~' or `='.
395 Report the status of background jobs immediately, rather than waiting until
396 just before printing a prompt.
398 : **pushd_ignore_dups** <grml>
399 Don't push multiple copies of the same directory onto the directory stack.
401 : **share_history** <grml>
402 As each line is added to the history file, it is checked to see if anything
403 else was written out by another shell, and if so it is included in the
404 history of the current shell too. Using !-style history, the commands from
405 the other sessions will not appear in the history list unless you explicitly
406 type the "history" command. This option is activated for zsh versions >= 4,
411 Apart from zsh's default key bindings, //grmlzshrc// comes with its own set of
412 key bindings. Note that bindings like **ESC-e** can also be typed as **ALT-e**
416 Edit the current command buffer in your favourite editor.
419 Deletes a word left of the cursor; seeing '/' as additional word separator.
422 Jump right after the first word.
425 Create directory under cursor or the selected area.
426 To select an area press ctrl-@ and use the cursor.
427 Use case: you type "mv abc ~/testa/testb/testc/" and remember that the
428 directory does not exist yet -> press **CTRL-xM** and problem solved.
431 Searches the last occurence of string before the cursor in the command history.
434 Display help on keybindings and zsh line editor. Press consecutively to page through content.
437 Brings a job, which got suspended with CTRL-z back to foreground.
440 == SHELL FUNCTIONS ==
441 //grmlzshrc// comes with a wide array of defined shell functions to ease the
444 : **855resolution()**

840 where own modifications should go. See also zshbuiltins(1) for a description
841 of the source command.
845 //grmlzshrc// comes with a wide array of predefined aliases to ease the user's
846 life. A few aliases (like those involving //grep// or //ls//) use the option
847 //--color=auto// for colourizing output. That option is part of **GNU**
848 implementations of these tools, and will only be used if such an implementation
851 : **acp** (//apt-cache policy//)
852 With no arguments prints out the priorities of each source. If a package name
853 is given, it displays detailed information about the priority selection of the
856 : **acs** (//apt-cache search//)
857 Searches debian package lists for the regular expression provided as argument.
858 The search includes package names and descriptions. Prints out name and short
859 description of matching packages.
861 : **acsh** (//apt-cache show//)
862 Shows the package records for the packages provided as arguments.
864 : **adg** (//apt-get dist-upgrade//)
865 Performs an upgrade of all installed packages. Also tries to automatically
866 handle changing dependencies with new versions of packages. As this may change
867 the install status of (or even remove) installed packages, it is potentially
868 dangerous to use dist-upgrade; invoked by sudo, if necessary.
870 : **ag** (//apt-get upgrade//)
871 Downloads and installs the newest versions of all packages currently installed
872 on the system. Under no circumstances are currently installed packages removed,
873 or packages not already installed retrieved and installed. New versions of
874 currently installed packages that cannot be upgraded without changing the install
875 status of another package will be left at their current version. An update must
876 be performed first (see au below); run by sudo, if necessary.
878 : **agi** (//apt-get install//)
879 Downloads and installs or upgrades the packages given on the command line.
880 If a hyphen is appended to the package name, the identified package will be
881 removed if it is installed. Similarly a plus sign can be used to designate a
882 package to install. This may be useful to override decisions made by apt-get's
883 conflict resolution system.
884 A specific version of a package can be selected for installation by following
885 the package name with an equals and the version of the package to select. This
886 will cause that version to be located and selected for install. Alternatively a
887 specific distribution can be selected by following the package name with a slash
888 and the version of the distribution or the Archive name (stable, testing, unstable).
889 Gets invoked by sudo, if user id is not 0.
891 : **ati** (//aptitude install//)
892 Aptitude is a terminal-based package manager with a command line mode similar to
893 apt-get (see agi above); invoked by sudo, if necessary.
895 : **au** (//apt-get update//)
896 Resynchronizes the package index files from their sources. The indexes of
897 available packages are fetched from the location(s) specified in
898 /etc/apt/sources.list. An update should always be performed before an
899 upgrade or dist-upgrade; run by sudo, if necessary.

1195 # always load the complete setup, even for root
1196 GRML_ALWAYS_LOAD_ALL=1
1200 Sourced right before loading //grmlzshrc// is finished. There is a global

1207 : **.important_commands**
1208 List of commands, used by persistent history (see above).
1211 = INSTALLATION ON NON-DEBIAN SYSTEMS =
1212 On Debian systems (http://www.debian.org) - and possibly Ubuntu
1213 (http://www.ubuntu.com) and similar systems - it is very easy to get
1214 //grmlzshrc// via grml's .deb repositories.
1216 On non-debian systems, that is not an option, but all is not lost:
1219 % wget -O .zshrc http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc
1222 If you would also like to get seperate function files (which you can put into
1223 your **$fpath**), you can browse and download them at:
1225 http://git.grml.org/?p=grml-etc-core.git;a=tree;f=usr_share_grml/zsh;hb=HEAD
1227 = ZSH REFCARD TAGS =
1228 If you read //grmlzshrc//'s code you may notice strange looking comments in
1229 it. These are there for a purpose. grml's zsh-refcard is automatically
1230 generated from the contents of the actual configuration file. However, we need
1231 a little extra information on which comments and what lines of code to take
1232 into account (and for what purpose).
1234 Here is what they mean:
1236 List of tags (comment types) used:
1238 Next line contains an important alias, that should be included in the
1239 grml-zsh-refcard. (placement tag: @@INSERT-aliases@@)
1242 Next line contains the beginning of an important function. (placement
1243 tag: @@INSERT-functions@@)
1246 Next line contains an important variable. (placement tag:
1247 @@INSERT-variables@@)
1250 Next line contains an important keybinding. (placement tag:
1251 @@INSERT-keybindings@@)
1254 Hashed directories list generation: //start//: denotes the start of a list of
1255 'hash -d' definitions. //end//: denotes its end. (placement tag:
1256 @@INSERT-hasheddirs@@)
1259 Abbreviation expansion list generation: //start//: denotes the beginning of
1260 abbreviations. //end//: denotes their end.
1262 Lines within this section that end in '#d .*' provide extra documentation to
1263 be included in the refcard. (placement tag: @@INSERT-abbrev@@)
1266 This tag allows you to manually generate refcard entries for code lines that
1267 are hard/impossible to parse.
1271 #m# k ESC-h Call the run-help function
1274 That would add a refcard entry in the keybindings table for 'ESC-h' with the
1277 So the syntax is: #m# <section> <argument> <comment>
1280 This tag lets you insert entries to the 'other' hash. Generally, this should
1281 not be used. It is there for things that cannot be done easily in another way.
1282 (placement tag: @@INSERT-other-foobar@@)
1285 All of these tags (except for m and o) take two arguments, the first
1286 within the tag, the other after the tag:
1288 #<tag><section># <comment>
1290 Where <section> is really just a number, which are defined by the @secmap
1291 array on top of 'genrefcard.pl'. The reason for numbers instead of names is,
1292 that for the reader, the tag should not differ much from a regular comment.
1293 For zsh, it is a regular comment indeed. The numbers have got the following
1318 So, the following will add an entry to the 'functions' table in the 'system'
1319 section, with a (hopefully) descriptive comment:
1322 #f1# Edit an alias via zle
1326 It will then show up in the @@INSERT-aliases-system@@ replacement tag that can
1327 be found in 'grml-zsh-refcard.tex.in'. If the section number is omitted, the
1328 'default' section is assumed. Furthermore, in 'grml-zsh-refcard.tex.in'
1329 @@INSERT-aliases@@ is exactly the same as @@INSERT-aliases-default@@. If you
1330 want a list of **all** aliases, for example, use @@INSERT-aliases-all@@.
1334 If you want to help to improve grml's zsh setup, clone the grml-etc-core
1335 repository from git.grml.org:
1337 ``` % git clone git://git.grml.org/grml-etc-core.git
1339 Make your changes, commit them; use '**git format-patch**' to create a series
1340 of patches and send those to the following address via '**git send-email**':
1342 ``` grml-etc-core@grml.org
1344 Doing so makes sure the right people get your patches for review and
1349 This manual page is the **reference** manual for //grmlzshrc//.
1351 That means that in contrast to the existing refcard it should document **every**
1352 aspect of the setup.

1355 the following pages:
