I'd like to output a list of all, currently not installed, packages (they are visible in Synaptic for example) using only shell commands.
How do I do this?
aptitude search '!~i'
See the Search Term Reference in the aptitude user's manual for details.
From the question's tags, I assume a Debian system.
aptitude search '!~i'. The list is very long (more than 30k lines).
It can be interesting to suppress virtual packages also:
aptitude search '!~i !~v'
Type the command as follows:
# rpm -qa > list.txt
with this command you can check your installed RPM list after that you can easly to find which RPM is not installed.
