wish restarting

[pankajpanjwani]

#!/bin/sh
# this will restart wishexec wish "$0" "$@"
the above works, but
the with csh... .

#!/bin/csh
# this will restart wishexec wish "$0" "$@"

doesn't work.

Been a long time since I've doen any C shell hacking. But it doesn't work in all probability simply because the Bourne shell and C shell have radically different syntax. The "exec" line shown above is Bourne shell syntax; there's no good reason to expect it to work with C shell.

Solution? Stick with the Bourne shell invocation. There's no compelling reason to craft a C shell version of the invocation. The Bourne shell runs only long enough to start the Tcl interpreter and pass any arguments to it. For an explanation of why this invocation is often needed and how it works, go to the Tcl'ers Wiki (

http://wiki.tcl.tk)

and check out the page "exec magic,"

Avia,
thanks for response. I am now more clear about the magic variables.
I could also find a solution to other problem of detecting the file type and invoking wish or tcsh accordingly.
thanks again
Pankaj
