Easily change environment variables and settings using bash

This script aim to manage multiple profile files for bash. It's like having multiple .bashrc files to load or unload when needed.
All you need to do is to create your custom profile files under ~/.bash_profiles directory. Each profile must have extension .load where you define variables, aliases and so on. You can optionally create files with extension .unload to clear what is loaded with a speficic profile.

Copy bash_profile_switcher.sh script in your homedir and source it at the end of your ~/.bashrc. Reload your shell or close terminal.

Use switch_profile function to manage profiles

 ~]$ switch_profile -h
switch_profile [options] profile

OPTIONS
  -k
    Keep env. Load selected profile without unloading current environment.
  -d
    Don't load profile. Unload current profile and don't load any profile in new bash shells
  -t
    Temporary profile. Load selected profile in current shell without starting it in new bash shells
  -l
    List available profiles
  -h Show help instructions (this help)

PROFILE
  A profile to load in ~/.bash_profiles. Profile files end with extension '.load' for loading (set variables) and '.unload' for unloading (unset variables)
  Current profile is stored in environment variable BASH_CURRENT_PROFILE and in file ~/.bash_saved_profile

Example:

  ~]$ switch_profile dev

  To load profile dev from ~/.bash_profiles/dev.load and unload it from ~/.bash_profiles/dev.unload

Create the following profile files in ~/.bash_profiles:

myprofile.load

export PS1="Funky Prompt:: \w ]\\$ "

myprofile.unload

unset PS1

Then load it with: switch_profile myprofile

• Spaces and blank characters are not supported on profile filenames
• Unload files must be written manually to match exactly what you loaded or defined
• Be careful when managing special variables like PATH
