Mark up matching text when using grep
TIL you can mark up matching text when using grep`.
I use grep
several times on a daily basis—usually to quickly find something in log files. The result of grep
can potentially be thousand lines. Luckily, we have the option --color
which marks up the matching text when using grep
.
According to man grep
:
--colour=[when, --color=[when]]
Mark up the matching text with the expression stored in GREP_COLOR environment variable. The possible values
of when can be `never', `always' or `auto'.
So if we would have a file with Lorem Ipsum text in it and we run the command:
grep --color "non" lorem.txt
The word non
will be highlighted in the result:

This really makes grepping easier 🤓
