Script molto comodo e utile, serve a controllare i pacchetti installati nel sistema e anche ad analizzarne il contenuto, veramente indispensabile.

<pre>
#!/bin/bash
# v. 0.0.3 - 14.08.05
#
# this script allows you to check (rapidly enough) the packages
# installed in your linux-box.
#
# (by gall0ws -at- tiscali -dot- it)
#
# suggestion: put this script in /usr/bin
#

# set some variables:
DIR=/var/log/packages # packages directory
PAGER=/usr/bin/less # set the default pager

# set the functions:
function usage() {
cat << USAGE
eg:
aboutpkg [ -e ] packagename

-d, --desc show package description (slack-desc)
-e, --examine examine the content of the packages
-l, --list show all packages installed
-L, --list-tidy show all packages by installation order
-s, --search [string] search the string in installed packages
-h, --help display this help and exit
