In the past I’ve posted an article regarding the basic usage of grep, one of the commands that I use daily at work to search a text within multiple files, or a text string in the list of running process of a Linux server, but I’ve forgot to show you a small and useful option : How to colour the output that you get from grep
to highlight the text you were searching for in a long line.
This is a small option of this powerful command but can save your eyes when searching for a particular property of a Java process that is 4 or 5 lines long.
To be honest I’ve realised this thanks to an article of Alessio, posted recently on his nice blog: http://dark-linux.net and so the following is the translation by me of his article in Italian with some small addition in examples and explanations.
