From: no.top.post on 27 Jul 2010 00:33 Someone kindly provided the following very useful one-liner to find all <recent> files containing 'a string':- find ./ -ctime -2 -exec grep -l "a string" {} \; Now I want command/s to find files containing MULTIPLE strings like: "dog", "cat", "fish" == TIA

Any of these work: find . -exec egrep -l "(dog|cat|fish)" {} + find . -exec grep -l "\(dog\|cat\|fish\)" {} + find . -exec grep -l -e dog -e cat -e fish {} + Regards, Clemens |
