How does shelljs.cat work?
shelljs.cat() is a function in the ShellJS library that reads and returns the contents of a file, or multiple files if provided as arguments, as a string or an array of strings. It supports file path expansion and globbing. It can also write the contents of the files to the console or a file if the -u or -o options are used.
