Simple utility to remove duplicate and manipulate PATH-like environment variables (e.g. LD_LIBRARY_PATH, MANPATH).

Project Description

Simple utility to remove duplicate in PATH-like environment variables.

On Unix, it outputs the transformed variable so it can be used like this :


On Windows, there is a helper .bat script that achieve the same effect (even if it is not as explicit):

C:\uniquepath.bat PATH

The command line also offers ways to append, prepend, and remove path to the variable and it supports wildcard (usefull for remove).


usage: [-h] [-v] [-r PATH] [-a PATH] [-p PATH]
                     [--separator CHAR] [--debug]

positional arguments:
  variable              environment variable or variable value to process.

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit
  -r PATH, --remove PATH
                        remove value(s) from the environment variable.
  -a PATH, --append PATH
                        append value(s) to the environment variable.
  -p PATH, --prepend PATH
                        prepend value(s) to the environment variable.
  --separator CHAR      changes the path separator (default is os specific).
  --debug               different output format more readable but invalid. DO
                        NOT ASSIGN to an environment variable.

On Windows: use uniquepath.bat helper script.

There are also 2 usage examples in the directory pyenv.bat (to switch python version) and the helper script uniquepath.bat for windows.
