I am in a shared account, and would like to fire up a tcsh shell from a command line, and specify a custom .tcshrc file to source for this shell. tcsh is being run from a bash shell.

An equivalent to:

tcsh (go into new shell)
source /tmp/myRCFile.tcsh

Is there a way to specify the source command before entering the new shell with an alias? Or is there a better way?

Thanks much as I'm very tired of typing this.

If you can live with spawning two shells (i.e. $SHLVL increasing by two):

tcsh -c 'source /tmp/myRCFile.tcsh; tcsh'

  • thank you for your answer, but yes would like to just spawn one shell if possible – koolunix Feb 12 '16 at 23:14

    Understood. However, I doubt that this is possible in tcsh without modifying the startup file. You could alias the source command to make it easier. You could hook into cd to get direnv-like directory-specific settings. You could also use expect as proposed by [this SO answer] (stackoverflow.com/a/32454088/201318). – kba stands with Monica Feb 13 '16 at 0:41
