  • Don't forget the other ways to change a directory, like pushd and popd.

    Also, I'd recommend an echo statement if the env was changed so you don't forget that it is happening.

    Might help in the future if you have an env related bug and forgot about this...

    And, thanks for the hint. I've been opening multiple terminals and setting up my "environment" for some items that I work on. May change based on this, since those changes are highly correlated to the directory structure I use for projects.
    • I deliberately left pushd and popd out because our env_setup actually does a heck of a lot more (like build separate test databases for each branch) and I use those for "alternate" navigation (though I know I can just do "builtin cd" :).

      The echo statement is a great idea, though. Thanks.

  • You probably want to have 'cd' also undo those environment changes when you change out of a directory that has that magic file in it. That's important if you're using this to do things like mess around with $PATH or $LD_LIBRARY_PATH.

    Nice trick though.

  • I just wrote a handful of bash functions to scratch this same itch, which also include some handy bash array functions and drhyde's suggestion of unsetting on exit.
