How to search for multiple patterns in multiple files using find or sed-CodePudding

grep -Zrl '$pattern1' /path/of/file | xargs -0 grep -rlZ '$pattern2' | xargs -0 grep -l '$pattern3' | xargs grep --color -C1 -E "$pattern1|$pattern2|$pattern3"

how to write the above command using sed or find.

The above command is basically searching 3 patterns at same time in multiple files.

CodePudding user response：

sed is Stream EDitor, might not be the best utility to use for searching patterns.

I'm guessing you're trying to grep 3 patterns in one set of files, which you already did in your last pipe:

grep --color -C1 -E "$pattern1|$pattern2|$pattern3"

I'd use find and grep together when I know there are some patterns in the filenames, then grep based on the results like:

find -iname '*pattern_in_filename*' -exec grep -E "$pattern1|$pattern2|$pattern3" {} ;
