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
29 VARIABLE (see below). Also the umask(1) for the root user is set to 022,
30 while for regular users it is set to 002. So read/write permissions
31 for the regular user and her group are set for new files (keep that
32 in mind on systems, where regular users share a common group).
35 Some of the behaviour of //grmlzshrc// can be altered by setting certain shell
36 variables. These may be set temporarily when starting zsh like this:
40 Or by setting them permanently in **zshrc.pre** (See AUXILIARY FILES below).
43 If set to a value greater than zero and //acpi// installed, //grmlzshrc// will
44 put the battery status into the right hand side interactive prompt.
46 : **COMMAND_NOT_FOUND**
47 A non zero value activates a handler, which is called when a command can not
48 be found. The handler is defined by GRML_ZSH_CNF_HANDLER (see below).
50 : **GRML_ALWAYS_LOAD_ALL**
51 Enables the whole grml setup for root, if set to a non zero value.
53 : **GRML_ZSH_CNF_HANDLER**
54 This variable contains the handler to be used by COMMAND_NOT_FOUND (see above)
55 and defaults to "/usr/share/command-not-found/command-not-found".
57 : **GRMLSMALL_SPECIFIC**
58 Set this to zero to remove items in zsh config, which do not work in
62 Where zsh saves the history. Default: ${HOME}/.zsh_history.
65 Number of commands to be kept in the history. On a grml-CD this defaults to
66 500, on a hard disk installation to 5000.
69 Sets the frequency in seconds for zsh to check for new mail. Defaults to 30.
70 A value of zero turns off checking.
73 Non zero values deactivate automatic correction of commands.
76 If set to zero (default), allows selection from a menu, if there are at least
77 five possible options of completion.
80 A non zero value disables precmd and preexec commands. These are functions
81 that are run before every command (setting xterm/screen titles etc.).
84 Show time (user, system and cpu) used by external commands, if they run longer
85 than the defined number of seconds (default: 5).
88 Number of commands to be stored in ${HISTFILE}. Defaults to 1000 on a grml-CD
89 and to 10000 on an installation on hard disk.
92 As in tcsh(1) an array of login/logout events to be reported by the shell
93 builtin "log". For details see zshparam(1). Defaults to (notme root).
95 : **ZSH_NO_DEFAULT_LOCALE**
96 Import "/etc/default/locale", if set to zero (default).
99 A non zero value causes shell functions to be profiled. The results can be
100 obtained with the zprof builtin command (see zshmodules(1) for details).
103 = FEATURE DESCRIPTION =
104 This is an in depth description of non-standard features implemented by
107 == DIRSTACK HANDLING ==
108 The dirstack in //grmlzshrc// has a persistent nature. It is stored into a
109 file each time zsh's working directory is changed. That file can be configured
110 via the **DIRSTACKFILE** variable and it defaults to **~/.zdirs**. The
111 **DIRSTACKSIZE** variable defaults to **20** in this setup.
113 The **DIRSTACKFILE** is loaded each time zsh starts, therefore freshly started
114 zshs inherit the dirstack of the zsh that most recently updated
117 == DIRECTORY BASED PROFILES ==
118 If you want certain settings to be active in certain directories (and
119 automatically switch back and forth between them), this is what you want.
122 zstyle ':chpwd:profiles:/usr/src/grml(|/|/*)' profile grml
123 zstyle ':chpwd:profiles:/usr/src/debian(|/|/*)' profile debian
126 When that's done and you enter a directory that matches the pattern
127 in the third part of the context, a function called chpwd_profile_grml,
128 for example, is called (if it exists).
130 If no pattern matches (read: no profile is detected) the profile is
131 set to 'default', which means chpwd_profile_default is attempted to
134 A word about the context (the ':chpwd:profiles:*' stuff in the zstyle
135 command) which is used: The third part in the context is matched against
136 **$PWD**. That's why using a pattern such as /foo/bar(|/|/*) makes sense.
137 Because that way the profile is detected for all these values of **$PWD**:
145 So, if you want to make double damn sure a profile works in /foo/bar
146 and everywhere deeper in that tree, just use (|/|/*) and be happy.
148 The name of the detected profile will be available in a variable called
149 'profile' in your functions. You don't need to do anything, it'll just
152 Then there is the parameter **$CHPWD_PROFILE** which is set to the profile,
153 that was active up to now. That way you can avoid running code for a
154 profile that is already active, by running code such as the following
155 at the start of your function:
158 function chpwd_profile_grml() {
159 [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
164 The initial value for **$CHPWD_PROFILE** is 'default'.
166 === Signaling availabily/profile changes ===
168 If you use this feature and need to know whether it is active in your
169 current shell, there are several ways to do that. Here are two simple
172 a) If knowing if the profiles feature is active when zsh starts is
173 good enough for you, you can put the following snippet into your
177 (( ${+functions[chpwd_profiles]} )) &&
178 print "directory profiles active"
181 b) If that is not good enough, and you would prefer to be notified
182 whenever a profile changes, you can solve that by making sure you
183 start **every** profile function you create like this:
186 function chpwd_profile_myprofilename() {
187 [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
188 print "chpwd(): Switching to profile: $profile"
193 That makes sure you only get notified if a profile is **changed**,
194 not everytime you change directory.
196 === Version requirement ===
197 This feature requires zsh //4.3.3// or newer.
200 == ACCEPTLINE WRAPPER ==
201 The //accept-line// wiget is the one that is taking action when the **return**
202 key is hit. //grmlzshrc// uses a wrapper around that widget, which adds new
205 This wrapper is configured via styles. That means, you issue commands, that look
209 zstyle 'context' style value
212 The context namespace, that we are using is 'acceptline'. That means, the actual
213 context for your commands look like: **':acceptline:<subcontext>'**.
215 Where **<subcontext>** is one of: **default**, **normal**, **force**, **misc**
219 === Recognized Contexts ===
221 This is the value, the context is initialized with.
222 The //compwarnfmt and //rehash// styles are looked up in this context.
225 If the first word in the command line is either a command, alias, function,
226 builtin or reserved word, you are in this context.
229 This is the context, that is used if you hit enter again, after being warned
230 about the existence of a _completion for the non-existing command you
234 This is the context, you are in if the command line is empty or only
235 consists of whitespace.
238 This context is in effect, if you entered something that does not match any
239 of the above. (e.g.: variable assignments).
242 === Available Styles ===
244 If you set this style to true, the warning about non existent commands,
245 for which completions exist will not be issued. (Default: **false**)
248 The message, that is displayed to warn about the _completion issue.
249 (default: **'%c will not execute and completion %f exists.'**)
250 '%c' is replaced by the command name, '%f' by the completion's name.
253 If this is set, we'll force rehashing, if appropriate. (Defaults to
254 **true** in //grmlzshrc//).
257 This can be a list of wigdets to call in a given context. If you need a
258 specific order for these to be called, name them accordingly. The default value
259 is an **empty list**.
262 The name of a widget, that is called after the widgets from 'actions'.
263 By default, this will be '.accept-line' (which is the built-in accept-line
267 If true in the current context, call the widget in the 'default_action'
268 style. (The default is **true** in all contexts.)
274 == GNU/SCREEN STATUS SETTING ==
275 //grmlzshrc// sets screen's hardstatus lines to the currently running command
276 or **'zsh'** if the shell is idling at its prompt. If the current working
277 directory is inside a repository unter version control, screen status is set
278 to: **'zsh: <repository name>'** via zsh's vcs_info.
281 == PERSISTENT HISTORY ==
282 If you got commands you consider important enough to be included in every
283 shell's history, you can put them into ~/.important_commands and they will be
284 available via the usual history lookup widgets.
288 == ENVIRONMENT VARIABLES ==
289 //grmlzshrc// sets some environment variables, which influence the
290 behaviour of applications.
293 If X is running this is set to "firefox", otherwise to "w3m".
296 Set to "yes". Some applications read this to learn about properties
297 of the terminal they are running in.
300 If not already set, sets the default editor. Falls back to vi(1),
301 if vim(1) is not available.
304 Some environment variables that add colour support to less(1) for viewing
305 man pages. See termcap(5) for details.
308 The mailbox file for the current user is set to /var/mail/$USER, if not
309 already set otherwise.
312 Set less(1) as default pager, if not already set to something different.
315 Holds the path to shared files for the C++ application framework QT
319 Set explicitly to /bin/zsh, to prevent certain terminal emulators to
320 default to /bin/sh or /bin/bash.
324 Apart from zsh's default options, //grmlzshrc// sets some options
325 that change the behaviour of zsh. Options that change Z-shell's default
326 settings are marked by <grml>. But note, that zsh's defaults vary depending
327 on its emulation mode (csh, ksh, sh, or zsh). For details, see zshoptions(1).
330 Zsh sessions, that use //grmlzshrc//, will append their history list to the
331 history file, rather than replace it. Thus, multiple parallel zsh sessions
332 will all have the new entries from their history lists added to the history
333 file, in the order that they exit. The file will still be periodically
334 re-written to trim it when the number of lines grows 20% beyond the value
335 specified by $SAVEHIST.
338 If a command is issued that can't be executed as a normal command, and the
339 command is the name of a directory, perform the cd command to that directory.
341 : **auto_pushd** <grml>
342 Make cd push the old directory onto the directory stack.
344 : **completeinword** <grml>
345 If the cursor is inside a word, completion is done from both ends;
346 instead of moving the cursor to the end of the word first and starting
349 : **extended_glob** <grml>
350 Treat the '#', '~' and '^' characters as active globbing pattern characters.
352 : **extended_history** <grml>
353 Save each command's beginning timestamp (in seconds since the epoch) and the
354 duration (in seconds) to the history file.
357 Whenever a command completion is attempted, make sure the entire command
358 path is hashed first. This makes the first completion slower.
360 : **histignorealldups** <grml>
361 If a new command line being added to the history list duplicates an
362 older one, the older command is removed from the list, even if it is
363 not the previous event.
365 : **histignorespace** <grml>
366 Remove command lines from the history list when the first character on
367 the line is a space, or when one of the expanded aliases contains a
368 leading space. Note that the command lingers in the internal history
369 until the next command is entered before it vanishes.
371 : **longlistjobs** <grml>
372 List jobs in long format by default.
375 Avoid to beep on errors in zsh command line editing (zle).
378 A wildcard character never matches a leading '.'.
381 Do not send the hangup signal (HUP:1) to running jobs when the shell exits.
383 : **nonomatch** <grml>
384 If a pattern for filename generation has no matches, do not print an error
385 and leave it unchanged in the argument list. This also applies to file
386 expansion of an initial `~' or `='.
389 Report the status of background jobs immediately, rather than waiting until
390 just before printing a prompt.
392 : **pushd_ignore_dups** <grml>
393 Don't push multiple copies of the same directory onto the directory stack.
395 : **share_history** <grml>
396 As each line is added to the history file, it is checked to see if anything
397 else was written out by another shell, and if so it is included in the
398 history of the current shell too. Using !-style history, the commands from
399 the other sessions will not appear in the history list unless you explicitly
400 type the "history" command. This option is activated for zsh versions >= 4,
405 Apart from zsh's default key bindings, //grmlzshrc// comes with its own set of
406 key bindings. Note that bindings like **ESC-e** can also be typed as **ALT-e**
410 Edit the current command buffer in your favourite editor.
413 Deletes a word left of the cursor; seeing '/' as additional word separator.
416 Jump right after the first word.
419 Searches the last occurence of string before the cursor in the command history.
422 Brings a job, which got suspended with CTRL-z back to foreground.
425 == SHELL FUNCTIONS ==
426 //grmlzshrc// comes with a wide array of defined shell functions to ease the
430 Converts plaintext files to HTML using vim. The output is written to
433 : **855resolution()**
434 If 915resolution is available, issues a warning to the user to run it instead
435 to modify the resolution on intel graphics chipsets.

469 Burns the files in ~/ripps (see audiorip() below) to an audio CD.
470 Then prompts the user if she wants to remove that directory. You might need
471 to tell audioburn which cdrom device to use like:
472 "DEVICE=/dev/cdrom audioburn"
475 Creates directory ~/ripps, if it does not exist. Then rips audio CD into
476 it. Then prompts the user if she wants to burn a audio CD with audioburn()

982 of the source command.
986 //grmlzshrc// comes with a wide array of predefined aliases to ease the user's
987 life. A few aliases (like those involving //grep// or //ls//) use the option
988 //--color=auto// for colourizing output. That option is part of **GNU**
989 implementations of these tools, and will only be used if such an implementation
992 : **acp** (//apt-cache policy//)
993 With no arguments prints out the priorities of each source. If a package name
994 is given, it displays detailed information about the priority selection of the
997 : **acs** (//apt-cache search//)
998 Searches debian package lists for the regular expression provided as argument.
999 The search includes package names and descriptions. Prints out name and short
1000 description of matching packages.

1003 Shows the package records for the packages provided as arguments.
1005 : **adg** (//apt-get dist-upgrade//)
1006 Performs an upgrade of all installed packages. Also tries to automatically
1007 handle changing dependencies with new versions of packages. As this may change
1008 the install status of (or even remove) installed packages, it is potentially
1009 dangerous to use dist-upgrade; invoked by sudo, if necessary.
1011 : **ag** (//apt-get upgrade//)

1015 currently installed packages that cannot be upgraded without changing the install
1016 status of another package will be left at their current version. An update must
1017 be performed first (see au below); run by sudo, if necessary.
1019 : **agi** (//apt-get install//)
1020 Downloads and installs or upgrades the packages given on the command line.
1021 If a hyphen is appended to the package name, the identified package will be
1022 removed if it is installed. Similarly a plus sign can be used to designate a
1023 package to install. This may be useful to override decisions made by apt-get's
1024 conflict resolution system.
1025 A specific version of a package can be selected for installation by following
1026 the package name with an equals and the version of the package to select. This
1027 will cause that version to be located and selected for install. Alternatively a
1028 specific distribution can be selected by following the package name with a slash
1029 and the version of the distribution or the Archive name (stable, testing, unstable).
1030 Gets invoked by sudo, if user id is not 0.
1032 : **ati** (//aptitude install//)
1033 Aptitude is a terminal-based package manager with a command line mode similar to
1034 apt-get (see agi above); invoked by sudo, if necessary.
1036 : **au** (//apt-get update//)
1037 Resynchronizes the package index files from their sources. The indexes of
1038 available packages are fetched from the location(s) specified in
1039 /etc/apt/sources.list. An update should always be performed before an
1040 upgrade or dist-upgrade; run by sudo, if necessary.

1349 = INSTALLATION ON NON-DEBIAN SYSTEMS =
1350 On Debian systems (http://www.debian.org) - and possibly Ubuntu
1351 (http://www.ubuntu.com) and similar systems - it is very easy to get
1352 //grmlzshrc// via grml's .deb repositories.
1354 On non-debian systems, that is not an option, but all is not lost:
1357 % wget -O .zshrc http://git.grml.org/f/grml-etc-core/etc/zsh/zshrc
1360 If you would also like to get seperate function files (which you can put into
1361 your **$fpath**), you can browse and download them at:
1363 http://git.grml.org/?p=grml-etc-core.git;a=tree;f=usr_share_grml/zsh;hb=HEAD
1365 = ZSH REFCARD TAGS =
1366 If you read //grmlzshrc//'s code you may notice strange looking comments in
1367 it. These are there for a purpose. grml's zsh-refcard is automatically
1368 generated from the contents of the actual configuration file. However, we need
1369 a little extra information on which comments and what lines of code to take
1370 into account (and for what purpose).
1372 Here is what they mean:
1374 List of tags (comment types) used:
1376 Next line contains an important alias, that should be included in the
1377 grml-zsh-refcard. (placement tag: @@INSERT-aliases@@)
1380 Next line contains the beginning of an important function. (placement
1381 tag: @@INSERT-functions@@)
1384 Next line contains an important variable. (placement tag:
1385 @@INSERT-variables@@)
1388 Next line contains an important keybinding. (placement tag:
1389 @@INSERT-keybindings@@)
1392 Hashed directories list generation: //start//: denotes the start of a list of
1393 'hash -d' definitions. //end//: denotes its end. (placement tag:
1394 @@INSERT-hasheddirs@@)
1397 Abbreviation expansion list generation: //start//: denotes the beginning of
1398 abbreviations. //end//: denotes their end.
1400 Lines within this section that end in '#d .*' provide extra documentation to
1401 be included in the refcard. (placement tag: @@INSERT-abbrev@@)
1404 This tag allows you to manually generate refcard entries for code lines that
1405 are hard/impossible to parse.
1409 #m# k ESC-h Call the run-help function
1412 That would add a refcard entry in the keybindings table for 'ESC-h' with the
1415 So the syntax is: #m# <section> <argument> <comment>
1418 This tag lets you insert entries to the 'other' hash. Generally, this should
1419 not be used. It is there for things that cannot be done easily in another way.
1420 (placement tag: @@INSERT-other-foobar@@)
1423 All of these tags (except for m and o) take two arguments, the first
1424 within the tag, the other after the tag:
1426 #<tag><section># <comment>
1428 Where <section> is really just a number, which are defined by the @secmap
1429 array on top of 'genrefcard.pl'. The reason for numbers instead of names is,
1430 that for the reader, the tag should not differ much from a regular comment.
1431 For zsh, it is a regular comment indeed. The numbers have got the following
1456 So, the following will add an entry to the 'functions' table in the 'system'
1457 section, with a (hopefully) descriptive comment:
1460 #f1# Edit an alias via zle
1464 It will then show up in the @@INSERT-aliases-system@@ replacement tag that can
1465 be found in 'grml-zsh-refcard.tex.in'. If the section number is omitted, the
1466 'default' section is assumed. Furthermore, in 'grml-zsh-refcard.tex.in'
1467 @@INSERT-aliases@@ is exactly the same as @@INSERT-aliases-default@@. If you
1468 want a list of **all** aliases, for example, use @@INSERT-aliases-all@@.
1472 If you want to help to improve grml's zsh setup, clone the grml-etc-core
1473 repository from git.grml.org:
1475 ``` % git clone git://git.grml.org/grml-etc-core.git
1477 Make your changes, commit them; use '**git format-patch**' to create a series
1478 of patches and send those to the following address via '**git send-email**':
1480 ``` grml-etc-core@grml.org
1482 Doing so makes sure the right people get your patches for review and
1487 This manual page is the **reference** manual for //grmlzshrc//.
1489 That means that in contrast to the existing refcard it should document **every**
1490 aspect of the setup.
1492 This manual is currently not complete. If you want to help improving it, visit
1493 the following pages:
