I’m managing a CentOS 4.7 server with several for security reasons shell-less user accounts. But sometimes I need a user-shell for installations anyway. What is the best way to get a login shell? Just now I use

sudo –u <user> bash –rcfile /home/<user>/.bash_profile

But this is not perfect. A lot of the environment variables are not intitialized.

  • A very quick suggestion: you might want to be specific about the environment variables you're finding aren't set to your liking. – esm Aug 4 '09 at 14:23
  • Especially HISTFILE and HOME were not set which annoyed me most. Anyway, esm provided the command I was looking for. – esc1729 Aug 4 '09 at 17:04

Try:

sudo -u <user> -H -- bash -l

The sudo argument "-H" will set the home directory properly, and the "-l" option to bash will indicate that this is a login shell. You might also experiment with adding the bash argument "-p".
