edit: wrapper script to launch editor

edit

#!/bin/bash

##############################################################################
# One command to edit files from the command line. Helps your muscle memory. #
#                                                                            #
# Do you instinctively write `mate` or `atom` to edit files, only to get     #
# told `command not found` because you forgot you are in a SSH session?      #
# The `edit` script is a simple wrapper that launches the command specified  #
# through the `$EDITOR`, `$VISUAL` or `$EDIT_EDITOR` environment variable.   #
# In this way, you will always use the same command to start editing files.  #
#                                                                            #
# To install:                                                                #
#                                                                            #
#     $ curl -LO https://git.io/edit; chmod +x edit                          #
#                                                                            #
