Unrar all multipart rar archives in directory

add a backup (or any other) suffix to a file
Very helpful when you've got complex filenames and needs to change just some small parts of it. Renaming a file called "i-made-a-small-typo-right-here" to "i-made-a-big-typo-right-here": $ mv -vi i-made-a-{small,big}-typo-right-here You could also copy multiple files, edit, remove, process, etc.

Run a command, redirecting output to a file, then edit the file with vim.
This is one of those 'nothing' shell functions ...which I use all the time. If the command contains spaces, it must be quoted, e.g. $ vimcmd 'svn diff' /tmp/svndiff.out If I want to keep the output of the command that I'm running, I use vimcmd. If I don't need to keep the output, I use this: $ vim

ls -qahlSr # list all files in size order - largest last
I find it useful, when cleaning up deleting unwanted files to make more space, to list in size order so I can delete the largest first. Note that using "q" shows files with non-printing characters in name. In this sample output (above), I found two copies of the same iso file both of which are immediate "delete candidates" for me.
