This is the PATH variable without sudo:
$ echo 'echo $PATH' | sh
This is the PATH variable with sudo:
$echo 'echo $PATH' | sudo sh
As far as I can tell, sudo is supposed to leave PATH untouched. What's going on? How do I change this? (This is on Ubuntu 8.04).
UPDATE: as far as I can see, none of the scripts started as root change PATH in any way.
From man sudo:
To prevent command spoofing, sudo checks ``.'' and ``'' (both denoting current directory) last when searching for a command in the user's PATH (if one or both are in the PATH). Note, however, that the actual PATH environment variable is not modified and is passed unchanged to the program that sudo executes.
