How do I test for TrueCrypt?

Question

I'm fairly certain my Ubuntu 11.10 install has truecrypt for my home directory, but how can I check. Preferably without rebooting into a live disk install?

Answer 1

The command

mount | awk '$3 == "'"$HOME"'"'

would give you an output line if your home is a mounpoint, with information about the type of filesystem. This should also allow to detect a truecrypt home folder.

Answer 2

If your home directory is encrypted (not truecrypted, there is difference), you can tell by looking for ~/.Private and ~/.ecryptfs in ls -la: ls -la | grep ".Private" for example.
