Unix – find files modified on a specific date / between two dates

“find” command is our friend here, using “-newer” argument. This is a 2-step process: create reference file(s) with required date limit(s) run find command with reference to this/these file(s) find all files modified after 2015/12/15 6:51pm and 2 seconds touch -t 201512151851.02 /tmp/t find . -newer /tmp/t find all files modified between two dates touch -t <date1> /tmp/t1 touch -t <date2> /tmp/t2 find . -newer /tmp/t1 -and -not -newer /tmp/t2 sources
