Deleting files - delete directory



  • **

    • Deleting files**
      To delete a file you must first have write permission to it. For information about permissions, click here. Once you have write permission, in a terminal run:
      **

      rm filename

    **
    There is no “Recycle Bin” in Linux so once you delete a file, it’s gone for good.
    When removing files, you may use an astrix (*) as a wildcard flag to remove certain files, for example if I wanted to remove all files that began with the letter j, I would run rm j*
    If anyone tells you to run rm -rf / as root, DO NOT LISTEN TO THEM. Running this command will delete all the files/directories on your Linux system.

    **

    • Deleting directories**
      If you have ownership to the directory and the directory is empty, you can simply type **

      rmdir directoryname

    ** to remove the directory. If the directory is not empty and you wish to simply delete it and all its contents, run **

    rm -rf directoryname
    

    **
    Please be careful with the -rf flag, as it will remove everything in the specified directory including sub directories. With root access and the rm -rf command you can wipe out your entire system if you make an error.

Tmux Commands

screen and tmux

A comparison of the features (or more-so just a table of notes for accessing some of those features) for GNU screen and BSD-licensed tmux.

The formatting here is simple enough to understand (I would hope). ^ means ctrl+, so ^x is ctrl+x. M- means meta (generally left-alt or escape)+, so M-x is left-alt+x

It should be noted that this is no where near a full feature-set of either group. This - being a cheat-sheet - is just to point out the most very basic features to get you on the road.

Trust the developers and manpage writers more than me. This document is originally from 2009 when tmux was still new - since then both of these programs have had many updates and features added (not all of which have been dutifully noted here).
