Commands tagged cd

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.

Alias two dots to move to parent directory. Put it into your .bashrc or .profile file.
