Version 1.0

 Usage: upath [-options] [envname..]
  --help | -h        Help info.
  --version | -V     Version info.

By default, environment variable PATH is assumed:

upath examines your environment variable, noting the order of the colon separated components. It then emits the components with the same ordering, but with duplicate directories eliminated.

After adding a directory to PATH for example, you can eliminate duplicates by doing:

PATH=$(upath)

Or for a different variable LD_LIBRARY_PATH:

LD_LIBRARY_PATH=$(upath LD_LIBRARY_PATH)

1. git clone https://github.com/ve3wwg/upath.git
2. cd ./upath
3. make
4. sudo cp upath /usr/local/bin/upath
