adding a user to cron.allow
Hello all,

I have solaris 10. I have have a script that installs crontab for a user. I want to add some more features to this script.

I want to check whether the user exists in etc/cron.d/cron.allow ... if yes then continue the script without adding .... if not, then add that user to the cron.allow.

Can any of you gurus out there help a newbie like me ?

Thanks.

Code:
user=whoever
grep "$user" etc/cron.d/cron.allow >/dev/null ||
  echo "$user" >> etc/cron.d/cron.allow

What scripting language/shell are you using?

Old 03-05-2009
You may want to grep for "^${user}$". "whoever" would match "whoeverr" or "iwhoever".

@dirk.diaglaow

I am using "ksh".

I didn't quite understand your second post.... should I just type ^${user}$ as it is ... because ^ can also be obtained by pressing ctrl+v .

I thank you for your continuing help.
