Make it a reusable function and add the -p flag to mkdir to create directories recursively usage: mydir some/dir/to/create

ksh's version of cd has an optional syntax where you can type "cd old new" and it will replace "old" with "new" in your current directory and take you there. This is very handy when you have a parallel directory structure, like source and object directories. As suggested, you can just type cd ${PWD/old/new} to get this in bash, but this function in your .bashrc will let you type the ksh cd syntax and avoid typing the special characters while preserving other cd functionality.

finds all epub files in the current directory and all child directories and converts them to .mobi format. all of the ebook-convert -options are optional; the only parameters you are required to pass are the incoming file and the outgoing file, with the extension. Has been tested on Ubuntu 10.10

I submitted a command like this without $0 if $BASH_SOURCE is unset. Therefor, it did only work when using ./script, not using 'sh script'. This version handles both, and will set $mydir in a script to the current working directory. It also works on linux, osx and probably bsd.

Should run with sudo

extracts path to each md5 checksum file, then, for each path, cd to it, check the md5sum, then cd - to toggle back to the starting directory. greps at the end to remove cd chattering on about the current directory.

Add DuckDuckGo Search as search provider on gnome-shell/gnome3 . Needs root permission. To see the results, use alt+f2 and then type r.

Move efficiently between directories. . This command adds a couple of extra features to cd, without affecting normal use. CDPATH use is also unaffected. It introduces and environment variable CDDIR which is used as an alternate home directory. . Note: I don't want to alter $HOME because then all my dot files will move. . Examples: . cd dir Change directory to "dir" (using CDPATH if necessary) . cd dir/file.txt Change directory to "dir" (containing folder of "file.txt") This allows you to cut'n'paste, or use . CDDIR is unset cd Change directory to $HOME . CDDIR=/home/flatcap/work cd Change directory to /home/flatcap/work . For convenience, put the command, and the following, in your .bashrc or .bash_profile export CDDIR="/home/flatcap/work" alias cdd="CDDIR=$(pwd)" Show Sample Output

Backup your entire system on a tar ball file format.

Simple tar pipe to be used to copy directories while including hidden files and maintaining file permissions

Let's say you have a set of files in tree A that you want duplicated to tree B while preserving their directory structure / hierarchy. (For example, you might want to copy your 'profile' model/views/controller from one Rails application to another.) The "pax" command will copy all matching files to the destination while creating any necessary directories.

Sometimes you need the full path to your script, regardless of how it was executed (which starting directory) in order to maintain other relative paths in the script. If you attempt to just use something simple like: STARTING_DIR="${0%/*}" you will only get the relative path depending on where you first executed the script from. You can get the relative path to the script (from your starting point) by using dirname, but you actually have to change directories and print the working directory to get the absolute full path.

If you have long and complicated folder names this might ease your work. add this into .bashrc Show Sample Output

as alternative to cd $OLDPWD

It gives a 'xcd' command for changing directory to one of CWDs of other ZSH processes (typically running in a terminal emulator). Useful for single-windowed terminal emulators like XTerm or Rxvt which don't have ability to pass CWD of one shell to another. Show Sample Output

I realise that this is just a reiteration of another entry (regardless of whether I came up with all this all by myself), but I would like present my additional alias' in context as a method of managing your directories. Rather convenient.

Had trouble with the other function, because of missing semicolons. (According to my bash on OS X)

Here's an alternative if you don't have seq.

In order to unrar several files in different subfolders, you just need to launch this command in your parent folder in order to have your files ready for manipulation and already extracted; I did not put anything to delete the original rar files
