Shell Programming and Scripting

User have given me about 450 commands, i just wanted to know the full path for those commands and the output should be redirected to a separate file.

Instead of running "which" command each time to find the path for all those commands, i need to do this in a simple way by a script.

Code:

which checkeq
which checknr
which chgrp
which chkey
which chmod
which chown
which chrtbl
which ckdate
which ckgid

Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!", "Doubt" or anything that does not accurately reflect the nature of your problem. Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.
