How do I get the prosaic description of a package using apt? I tried both apt-cache show and apt-cache showpkg but no luck.

Using synaptic it's easy as typing the package name and the description is given by the standard view, but sometimes I'd prefer to just use apt-cache, for example from terminal.

apt-cache show shows the package description int the Description: field. What else are you looking for? – enzotib Jun 19 '11 at 20:56
"apt-cache show <package name>" shows the Description if the package is known to the system. In what way is it not working for you? – Flimzy Jun 19 '11 at 20:56
@enzotib I oversighted the output. apt-cache show does exactly the thing I asked for. – Paolo Jun 19 '11 at 21:07

If you would just use apt-cache search package-name, all packages with "package-name" in it would be returned. To limit to a package named "package-name", use:

apt-cache search ^package-name$

You can do this with aptitude as in:

aptitude show package-name

apt-cache show <packagename> does what you want. You might have overseen it. The following command highlights it:

apt-cache show scons | grep --color -E "Description|$"

Assuming you are looking for a specific package, I believe the following is what you are in search of:

apt-cache search some-pkg

If I have misunderstood what you are trying to do, please let me know.
