Sometimes you get "command not found" unless you use "sudo"
(I had this in Wheezy with the fsck command)
Code:
andypugh@linuxcnc-26-debian:~$ fsck
bash: fsck: command not found
andypugh@linuxcnc-26-debian:~$ sudo fsck
[sudo] password for andypugh:
fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
/dev/sda1 is mounted.
e2fsck: Cannot continue, aborting.
