In this video I cover the rev or revers command in Linux. The rev command reverse lines characters. It comes with the util-linux package and can take input from a file or stranded out.
I think this command is little know because it doesn’t have many uses and there are other ways of doing it.
In this video I wanted to cover something fun so I chose the sl command in Linux and Unix systems. SL stands for Steam Locomotive and its a joke for typed ls commands.
One thing I didn’t share in the video is capital LS is a link to sl and not a alias. At least in mint Linux.
In this video we cover Linux strings and how to print printable characters in a binary file.
First we look at the strings man page and then we go over some examples
$ strings [file]
