Rep:
USER doesn't keep the login username after "su -":
Code:
-bash-2.05b$ who am i
jlliagre console Jun 5 07:55
-bash-2.05b$ cat /etc/redhat-release
CentOS release 3.7 (Final)
-bash-2.05b$ echo $USER
jlliagre
-bash-2.05b$ su -
-bash-2.05b# who am i
jlliagre console Jun 5 07:55
-bash-2.05b# echo $USER
root
thats interesting if i use "su" i can use the $USER and it will stay as origional user, if i "su -" then use $USER it will change to root. And if i kdesu like i am now i guess it must keep origional user as well because my script works properly so it must keep $USER as origional, you try it with "su" and not "su -"
this variable is set by bash, so if you use #!/bin/bash as first line of your script, everything should be fine. see "man bash" for other builtin variables...
