Find to find files newer than
find . -newermt '14 days ago' ## minutes/hours etc.. see date input formatsView content of all files including filename
In this example I get the ruby-version of my projects.
tail -n +1 */.ruby-versionWhich results in the following output
==> project1/.ruby-version <==
2.5.1
==> project2/.ruby-version <==
3.0.0
==> project3/.ruby-version <==
2.7.2
