====== Ubuntu - Packages - Find Package Dependencies ======

Issue the command:

<code bash>
aptitude search ~Dpackage_name
</code>

----

===== Script =====

This is a script that will recursively show dependencies of packages:

<file bash>
#!/bin/bash
#
# Recursively show dependencies of packages.

pkgdep() {
  apt-cache depends --installed $1 | awk -F\: '{print $2}' | grep -v -e '<' -e '>' | awk 'NF'
}

for i in $(pkgdep $1); do
  pkgdep $i
done | sort -u

Save and **chmod +x**.  Execute with one package as parameter.

If you also want non-installed packages shown, remove the **<nowiki>--installed</nowiki>** parameter.
