WSL launch atom

atom

#!/bin/bash

function help {
  echo "Edit WSL files or directories in atom, on Windows.

Usage:
  $( basename $0 ) [ FILE_OR_DIRECTORY | -l PHRASE ] ...

FILE_OR_DIRECTORY can either be absolute or relative to the current directory.
If no arguments are specified, the current directory is assumed.

If the -l option is provided, the current git repository is searched for PHRASE,
and the files that the token are found in are edited.
The cursor is placed on the first line of each file that contains PHRASE.

Examples:
  $ atom   # Edit current directory
  $ atom . # Edit current directory
  $ atom blah.html # Edit ./blah.html
  $ atom blah.html ick.html # Edit ./blah.html and ./ick.html
  $ atom ~ # Edit home directory
  $ atom ~ . # Edit home and current directories
  $ atom -l blah  # Edit all files in the current git repo that contain the word blah
  $ atom -l blah -l ick  # Edit all files in the current git repo that contain the word blah or ick
"
