You may arrive in a situation where you may want to “extract” out text between two words. For example to view the latest changelog (where x.x.x is the latest version) in a CHANGELOG.md file.

Below are a bunch of easy one-liner commands that gives information about various aspects of your Linux machine.

If you are a developer then fixing bugs takes time because you have to shift from terminal to your fav browser & then type your query. (and then in between you open reddit/twitter 😅 for some reason, which wanders your attention).

To find last modified file

find Documents/ -mtime -1

where mtime means “Last Modification Time”
