How to list all commands in a package?

Question

I just downloaded the w3c-markup-validator package from the universe repositories, but I can't seem to figure out how to run it. How can I list the new commands available?

Answer 1

dpkg -L w3c-markup-validator

More generically, dpkg -L [packagename]

Answer 2

dpkg -L w3c-markup-validator lists all the files in the package. You want the executables in the path, so

dpkg -L w3c-markup-validator | grep /bin/

will provide a good approximation. If you want to be really precise, here's a regexp that will retain only files in the directories in your $PATH.

dpkg -L bash | grep -E "^${PATH//:/\/|^}\$"

Answer 3

If you want to find out beforehand you can search at packages.ubuntu.com as well.

Answer 4

If you use synaptic, then you can right click on the package, click properties and see installed files. Any files installed under /usr/bin or similar locations would be commands.
