How can I grep while avoiding 'Too many arguments' [duplicate]

Answer 1

Using xargs is more efficient than using "find ... -exec grep" because you have less process creations etc.

One way to go about this would be:

ls 1US* | xargs grep -i user@domain.com | awk -F: '{print $1}' | xargs rm

But easier would be:

find . -iname "1US*" -exec rm {} \;
