I am working on a machine that has some user accounts that are dynamically generated, and therefore I can not user customize the .bashrc or .profile.

I frequently need to use these accounts to change some configurations; to do so I sudo su into them.

My issue is that on my user account I have configured a lot of aliases that I have come to use without even thinking about, aliases that do not exist for this sud user.

Is there a way, from my shell, to automatically source a specific file when only I su to a user?

you can simply start your bash with the --rcfile /path/to/script flag. to be specific, use

sudo -u $USER bash --rcfile /path/to/file

make sure not to cover bash --rcfile /path/to/file by double quotes, because if so, sudo will not find the bash command.

You could also make a function containing that with the user as parameter $1

  • He there, I just tried this out but it does not seem to be working. I tried it with the given command however I do not have the pass of the user I am trying to become, I am using sudo. I tried prepending sudo to this command with no luck. bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell – Matt Clark Aug 10 '15 at 14:55

    Oh... no sorry, didn't read your question well. if you use sudo you better should use sudo -u $USER bash --rcfile /path/to/file. in that case you could function that like sudo -u $1 bash --rcfile /path/to/file – Schwertspize Aug 10 '15 at 16:09
