When used with -c option it reverse the characters of each line as well. For example, Lets say below are the file contents of your file. This is line 1 This is line 2 This is …

Bind is to connect keys to a command or string of specified commands, echo is to output text to the console, and alias is a command that allows you to create a new command out of a string of specified commands. Basically, I can do math without using math. This is pure connectionism, where there are no values, no logic operators and no measurements in the logic. It is purely making, breaking and using connections …
