work for execute file

Also resolves symlinks, showing the full path of the link target

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:

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.

Usage: upto directory

Usage: jd dir

Requires globstar. To set globstar use:

The biggest advantage of this over the functions is that it is portable.

Put the function in your .bashrc and use "map [alias]" to create the alias you want. Just be careful to not override an existing alias.

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:

.

Change directory to "dir" (using CDPATH if necessary)

.

Change directory to "dir" (containing folder of "file.txt")

This allows you to cut'n'paste, or use

.

CDDIR is unset

Change directory to $HOME

.

CDDIR=/home/flatcap/work

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)"

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.

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.

This creates a bash function `take` that you can call with the name of the directory as the first parameter. Add the function to ~/.bashrc to have it available anytime.

Make it a reusable function and add the -p flag to mkdir to create directories recursively

usage: mydir some/dir/to/create

Create a directory called "dirname" and navigate into it.

Obviously the example given is necessarily simple, but this command not only saves time on the command line (saves you using "cd -" or, worse, having to type a fully qualified path if your command cd's more than once), but is vital in scripts, where I've found the behaviour of "cd -" to be a little broken at times.

This is useful for quickly jumping around branches in a file system, or operating on a parellel file.

This is tested in bash. cd to (substitute in PWD, a for b) where PWD is the bash environmental variable for the "working directory"

Makes bash-4.x like zsh. Automatic cd into a directory if a command with that name doesnt exists. Ready for your ~/.bashrc file

This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead.

I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'.

combines mkdir and cd

added quotes around $_, thanx to flatcap!

Instead of typing "cd ../../.." you can type ".. 3". For extremely lazy typists, you can add this alias:

alias ...=".. 2" ....=".. 3"

- so now you can write just .... !!!

NB the .. function needs to be "source"d or included in your startup scripts, perhaps .bashrc.

This uses mpg123 to convert the files to wav before burning, but you can use mplayer or mencoder or ffmpeg or lame with the --decode option, or whatever you like.

Change to your taste. Much quicker than having to add 'cd' every time. Add it to your .bashrc or .bash_profile.

This is a kind of wrapper around the shell builtin cd that allows a person to quickly go up several directories.

Instead of typing:

cd ../..

A user can type:

cd ...

Instead of:

cd ../../..

Type:

cd ....

Add another period and it goes up four levels. Adding more periods will take you up more levels.

Another way of doing it that's a bit clearer. I'm a fan of readable code.

How often do you make a directory (or series of directories) and then change into it to do whatever? 99% of the time that is what I do.

This BASH function 'md' will make the directory path then immediately change to the new directory. By using the 'mkdir -p' switch, the intermediate directories are created as well if they do not exist.
