SUMMARY: Script question - How to execute command passed to scri pt.

I know this list was fast. The winner goes to Ramiro Santos with a response
time of less that 5 minutes.

try exec $1 (the first argument in the list)

My opinion is that tehe message is comming from the command itself and not
from the script.

Cheers

Also to Lieven Marchand [lieven.marchand@just.fgov.be] with the following
response.


If all you want to do is change the environment, consider using env

env FOO=BAR PATH=/bin command

Otherwise, end your script with an exec of the command (after having
exported the changed environment).


Thanks,

I have changed the script to 

	/usr/local/execute
	#!/bin/csh
	# This script takes command arguments, establishes environment for
the user and then executes the argument
	#
	#  (Establish my environment here (Path, LD_LIBRARY_PATH etc.))

	echo "Executing command ${*}"
	exec ${*}

It works like a charm.
