It should be ".... | xargs rm"

You had "| rm xargs " and I have no idea what that will do.

I am sorry.for typographical error....Its just the way, u wrote it
"xargs rm"

below also will give the same result...why to pipe?

Code:

find  /inbound/etl/dev/CMD/  -type f -mtime +21 -exec rm {} \;

Why to pipe instead of an extra fork/exec all for each file to be removed? <sarcasm>Hrmmmmm.</sarcasm>

Additionally, the -exec syntax is more treacherous for beginners, especially when doing something like "rm". Finally, there is an advantage (espcecially to noobs) to not need to change the find command in order to do the final step.

Finally, xargs is a really awesome tool and it should be in every noob's toolset.

This is my first time to use xargs ..really man WOOOOOOW such a wonderful tool ...I have read the man page and some exapmle about it what a great tool

really thanks otheus

What xargs does is convert the output as arguments for the next command.
redirection > makes the stdout of a command to be saved in a file.
piping | makes the stdout of a command to be the stdin of the next command
xargs -0 is an useful option often used with find. This will eliminate most of the problems with space between filenames.
xargs -I alias is another useful option which helps to command more conveniently and also i've seen somethings dont work without this option. dunno why..
