getting packages info on Ubuntu

Standard

Recently we’ve decided to move all our CentOS 5 server installations to a more modern, and bioinformatics friendly, environment. So the choose was on Ubuntu, in it’s 12.04 LTS version.

Some commands are different, especially those for exploring packages, their releases and such.

For example to see what packages install $something now I do a:

sudo apt-file search $package

while to see a package’s details, for example nano, I give a:

sudo apt-cache show nano

Description-en: small, friendly text editor inspired by Pico
 GNU nano is an easy-to-use text editor originally designed as a replacement
 for Pico, the ncurses-based editor from the non-free mailer package Pine
 (itself now available under the Apache License as Alpine).
 .
 However, nano also implements many features missing in pico, including:
  - feature toggles;
  - interactive search and replace (with regular expression support);
  - go to line (and column) command;
  - auto-indentation and color syntax-highlighting;
  - filename tab-completion and support for multiple buffers;
  - full internationalization support.

That’s all (for now).
