The admin might not have even installed bash (or your preferred shell). @Stephan: Thats because you might not have a choice to choose your shell if you are logging onto a remote server.

That avoids any question of "to which shell must i adapt myself for this session?" Why not just ENSURE that you’re running a specific (preferred) shell by calling:

exec /bin/bash

?

That avoids any question of “to which shell must i adapt myself for this session?”

It does not work on redirection. On machines that drop me into a non-BASH shell, I usually write a .rc file and execute bash there to launch BASH. For example, when one of the machines drops me into TCSH, I write a .tcshrc file containing this: alias | awk -F' ' '{ print "alias "$1"=\""$2" "$3" "$4" "$5" "$6" \""$7""; }' > .bash_aliases bash and in .bashrc file, I write the following export PS1=[\\u@\\h:\\w]\$\ export PS2=\> export PS4=+ . .bash_aliases This brings me inside a BASH shell, but echo $SHELL still prints /bin/tcsh.
