Re:Ask HN: Is there a way to make bash history dir specific? by devnonymous on Wednesday May 25, 2016 @05:40AM (#11768645)
There isn't an builtin way to do this in bash but what you are asking for is 2 things:

* Trigger an action on changing a directory

* That action should be to change your bash history file

The second part is pretty easy to do -- you just change the $HISTFILE environment variable and export it. For the first part though, you can either use a naive little function that replaces bash's builtin `cd`[1] or you can use any one of the many tools specifically created for this sort of a thing:

  http://swapoff.org/ondir.html
  https://github.com/kennethreitz/autoenv
  http://direnv.net/
  https://github.com/cxreg/smartcd
Note however, that most unix tools are angnostic to the current working dir so...

  $ /path/to/cmd /some/other/path/to/argument
  $ cd /path/to && ./cmd /some/other/path/to/argument
  $ cd /some/other/path/to && /path/to/cmd argument
...might all do the same thing but will be saved in different history files if you implement what you need.
