My custom jump marks implementation based on that by @jeroenjanssens and things I've found on the net.

checkout the repo add a source directive to your .bash_profile, .bashrc or wherever else you prefer.

source /path/to/.jump_marks file

and re-source (type source ~/.bash_profile) or logout and back into your terminal

There's an osx marks function in the file you'll need to uncommment that and comment out the original function

• cd to a dir and type:
• mark to create a mark using the current directory name, or
• mark <alias> to mark the directory using the given alias.
• Type marks to list your existing marks
• jump <alias> to jump (change dir) to the given mark
• unmark <alias> to remove the mark

jump and unmark both have command completion i.e. type jump a<tab> to get all marks beginning with a

if you use jump or unmark with no parameters you'll be given a choice of mark aliases to choose from

automatic OS detection to switch the marks function depending on whether it's OSX or not Update to use zsh autocompletion if zsh is being used.
