Hi all,

While answering a question, I came across a gap in my own knowledge. Now, I've picked up from somewhere that the 'sh' shell (specifically, if you select it as your login shell) is essentially a symlink to the system default shell, usually bash. However, while double-checking this before posting along these lines, I found web pages claiming that it's still installed on all Linuxes, and implying that it's called if the shabang in a script is /bin/sh. Can someone take the time to confirm for me what the 'sh' shell does in various situations?

Thanking you in advance,
Andrzej

This depends on the distro. On most Linux distros /bin/sh is a symlink to /bin/bash, but on others its not.
