Determine user id in a script

[alan147]

Hi

I am writing some scripts that need to be executed by a specific user. Is ther a way I can include a check of the user id in the script so that if the user id is incorrect the script will warn the user and then exit?


Thanks

Alan

Try id

 

[dickiebird]

#!/bin/ksh
YOURUSER=avalidusername
#or YOURUSER=`cat valid_user_file`
if [ $USER != $YOURUSER ]
then
echo "You can't do this - Goodbye !"
exit
fi
.
.
etc

HTH ! Dickie Bird (-)))

test $UID -eq $mynumber || exit 1 > /dev/null

Thanks for your help.

I have just tried Dickie's suggestion which does just what I want.

what about someoneelse else do:
$ export USER=youruser
$ ./your_script

I suppose thatthe best solution is:
chown youruser your_script
chmod 600 your_script
(as long as you ar the root) __

#!/bin/ksh
#
# a slight variation on dickiebird's suggestion
#
YOURUSER=avalidusername
IAM=$(id | nawk -F '[()]' '{print $2}')

if [ "${IAM} != "${YOURUSER}" ]
then
echo "You can't do this - Goodbye !"
exit
fi vlad
