Question

I have my projects in a ~/Documents/EP_example_project naming scheme. They all live under ~/Documents.

I would like to create a bash-function that allows me to cd into a project-directory from whereever I am on the system; with autocomplete. Like so:

cdp E<tab>
# ... EAP_example_additional_project EP_example_project
P<tab>
# prompt now says:
cdp EP_example_project<enter>
# ... And I am in the project-directory.

That would be a bit easier then typing cd ~/Do<tab>EP<tab> everytime.

I do know the basics about creating a simple function, but cannot find how to add tab-autocompletion to that.

NOTE: while above reasoning makes little sense: the additional ~/Do is not that much overhead, it is the additional things I can do in such a function, like print the contents of a certain file if found (.birdseye), list the projects contents, last accessed dates and so on, that make this more interesting in future.

Answer 1

You could consider CDPATH. You can export CDPATH=~/Documents to have all the directories under ~/Documents added for autocompletion. You can have a function or alias for this export command and set & unset CDPATH as and when you need.
Hope this helps!
