title: run csh scripts from bash, change shell temporary via command
body: <p>I need to run csh scripts from a bash shell and therefore temporary change to tcsh via a command. It works perfect in interactive mode but i cant figure out in a one line command.
  So in interactive mode i do in the bash shell:</p>
  
  <p>tcsh </p>
  
  <p>source my.tcshr</p>
  
  <p>useMyTcshCmd</p>
  
  <p>etc.</p>
  
  <p>How can i do all of this in 1 command?
  Sorry for the newbie question...</p>
