Writing multiple lines of code to a file in linux

Sometimes it’s needed to create multiple files, repeatadly with linux. This should work with any of the major distros: CentOS, Ubuntu, Fedora, Debian, etc.

This also assumes the file does not exist already, if it does exist, it will append this info to the end of the file that already exists.

You can now type cat ifcfg-eth0 and it will output the 4 lines above.

If that is not to your liking, you could always use something like echo with append statements. Like this:

The >> option appends the echo information into a file name. But if you do > it will overwrite all lines in the file.

Enjoy!
