implementations of these tools, and will only be used if such an implementation
is detected.
+: **acp** (//apt-cache policy//)
+With no arguments prints out the priorities of each source. If a package name
+is given, it displays detailed information about the priority selection of the
+package.
+
+: **acs** (//apt-cache search//)
+Searches debian package lists for the regular expression provided as argument.
+The search includes package names and descriptions. Prints out name and short
+description of matching packages.
+
+: **acsh** (//apt-cache show//)
+Shows the package records for the packages provided as arguments.
+
+: **adg** (//apt-get dist-upgrade//)
+Performs an upgrade of all installed packages. Also tries to automatically
+handle changing dependencies with new versions of packages. As this may change
+the install status of (or even remove) installed packages, it is potentially
+dangerous to use dist-upgrade; invoked by sudo, if necessary.
+
+: **ag** (//apt-get upgrade//)
+Downloads and installs the newest versions of all packages currently installed
+on the system. Under no circumstances are currently installed packages removed,
+or packages not already installed retrieved and installed. New versions of
+currently installed packages that cannot be upgraded without changing the install
+status of another package will be left at their current version. An update must
+be performed first (see au below); run by sudo, if necessary.
+
+: **agi** (//apt-get install//)
+Downloads and installs or upgrades the packages given on the command line.
+If a hyphen is appended to the package name, the identified package will be
+removed if it is installed. Similarly a plus sign can be used to designate a
+package to install. This may be useful to override decisions made by apt-get's
+conflict resolution system.
+A specific version of a package can be selected for installation by following
+the package name with an equals and the version of the package to select. This
+will cause that version to be located and selected for install. Alternatively a
+specific distribution can be selected by following the package name with a slash
+and the version of the distribution or the Archive name (stable, testing, unstable).
+Gets invoked by sudo, if user id is not 0.
+
+: **ati** (//aptitude install//)
+Aptitude is a terminal-based package manager with a command line mode similar to
+apt-get (see agi above); invoked by sudo, if necessary.
+
+: **au** (//apt-get update//)
+Resynchronizes the package index files from their sources. The indexes of
+available packages are fetched from the location(s) specified in
+/etc/apt/sources.list. An update should always be performed before an
+upgrade or dist-upgrade; run by sudo, if necessary.
+
: **cmplayer** (//mplayer -vo fbdev//)
Video player with framebuffer as video output device, so you can watch
videos on a virtual tty. Hint: Using fbdev2 allows you to use the shell
Prints the summarized disk usage of the arguments as well as a grand total
in human readable format.
+: **dir** (//ls -lSrah//)
+Lists files (including dot files) sorted by size (biggest last) in long and
+human readable output format.
+
: **fblinks** (//links2 -driver fb//)
A Web browser on the framebuffer device. So you can browse images and click
links on the virtual tty.
Lists files in long colored output format. Including file names
starting with ".".
+: **lad** (//ls -d .*(/)//)
+Lists the dot directories (not their contents) in current directory.
+
: **lh** (//ls -hAl --color=auto//)
Lists files in long and human readable output format in nice colors,

+: **lsa** (//ls -a .*(.)//)
+Lists dot files in current working directory.
+
: **lsbig** (//ls -flh *(.OL[1,10])//)
Displays the ten biggest files (long and human readable output format).
: **lse** (//ls -d *(/^F)//)
Shows empty directories.
+: **lsl** (//ls -l *(@)//)
+Lists symbolic links in current directory.
+
: **lsnew** (//ls -rl *(D.om[1,10])//)
Displays the ten newest files (long output format).
: **lsold** (//ls -rtlh *(D.om[1,10])//)
Displays the ten oldest files (long output format).
+: **lss** (//ls -l *(s,S,t)//)
+Lists files in current directory that have the setuid, setgid or sticky bit
+set.
+
: **lssmall** (//ls -Srl *(.oL[1,10])//)
Displays the ten smallest files (long output format).
Grants read, write and execute permission of a file to the owner and
