Commands using apt

This let's you find out the total packages that have available upgrades. Usefull if you want to check or show the total available upgrades on your system.

Shows all configurations to apt and dpkg, rarely changed, you probably still have the default configuration. Go ahead and explore your configuration if you dare, perhaps change your apt-cache directory, Dir::Cache "var/cache/apt/"; or the names of the log files.

since awk was already there one can use it instead of the 2 greps. might not be faster, but fast enough

Use this command to determine what version of MythTV you are running on a Debian system. Tested on a Mythbuntu installation.

I used this to mass install a lot of perl stuff. Threw it together because I was feeling *especially* lazy. The 'perl' and the 'module' can be replaced with whatever you like.

replace apt-get with your distro's package manager.

Where 'something' is the package name, and 'specific' is what you're specifically looking for.

This helps if your query is 2+ words long.

If there is update available for the package you can see upgrade is from which version to which version. Also you will get detail about which release the package belongs to (stable/testing/sid).

if you don't want to show string "version?, then use awk or cut filter it: apt-cache show pkgname | grep -i "version:" | awk '{ print $2 }'

we can also use regex to search many packages and show their versions:

apt-cache search pkgregex | grep -i "version:"

That command installs "most" and make this command as the default man reader. The "most" works like "less" (the current man reader), but it render colors for manpages and may do more things. Read "man most".

Create Debian package dependency graph using GraphViz

search ubuntu's remote package source repositories for a specific program to see which package contains it

this is funny ;)

alias sl="ls" ... is the useful solution, but that's boring ;P and You won't learn to think before You type !

For example: check the APT security keys to make sure the Google digital signature was imported correctly
