The apt-cache command line tool is used for searching apt software package cache.
To list all the available packages, type this command:
$ apt-cache pkgnames
You can pipe the output of this command to less or more
$ apt-cache pkgnames | less
$ apt-cache pkgnames | more
Less allows you to scroll from within even a non-scrollable terminal, more prints a page then you press enter to bring up every line after that.
To find out the package name and it's description, use the "search" flag.
For example, you can search for gnome-mines.
$ apt-cache search gnome-mines
This is the output:
gnome-mines - popular minesweeper puzzle game for GNOME
gnomine - popular minesweeper puzzle game for GNOME (transitional package)
To display all packages starting with word "fire" ( you can use whatever) type:
$ apt-cache pkgnames fire
If you want to display package version number, check sums, size, installed size, category... use show:
$ apt-cache show firefox
To check dependencies for specific packages use showpkg.
$ apt-cache showpkg firefox
The stats sub command will display overall statistics about the cache.
$ apt-cache stats
You can use ncurses interface or search through cli.
To run aptitude with ncuses interface:
