Change user, assume environment, stay in current dir

su -- user
I've used this a number of times troubleshooting user permissions. Instead of just 'su - user' you can throw another hyphen and stay in the original directory.
Sample Output
[root@localhost local]# pwd
/usr/local
[root@localhost local]# su -- user
[user@localhost local]$ pwd
/usr/local
[user@localhost local]$

What Others Think

This doesn't assume the user's environment. "su -- user" == "su user". By using "--" you are just telling the command "su" to ignore any following strings that look like options. Not too useful on "su" commands, but to grep a file for the string "-r": grep -- -r file
