‘dpkg –get-selections > installed-software.log’

should be:
‘dpkg –get-selections > installed-software.log’

the M dash ‘–’ is replaced with two ‘–’

I think it's possible too, but I don't know how. Nice site! Thanks for posting! And do you know how to do this on a FreeBSD machine? I think it’s possible too, but I don’t know how.

I usually use this, which is an improvement: dpkg --get-selections | grep "\binstall\$" | cut -f 1 | while read f ; do c=$(apt-cache rdepends "$f" --installed | wc -l) ; if (($c == 2)) ; then echo -e "$f" ; fi ; done This oneliner shows the 'root' packages between installed ones. 'Root' means they do not have other packages depending on them. This makes the minimal subset of 'apt-get install' targets to get a system like the actual. Please, notice metapackages are always shown as root, because nobody depends on them. So the result still has some redundancy. Enjoy it. The solution proposed for Debian lists too many packages.
