Bash script to activate virtual environments by name

activate

#!/bin/bash
#
# virtualenvs must be in `~/venv`
# save this as /usr/local/bin/activate
# file is sourced instead of executed - need read permissions only
# `sudo chmod 644 /usr/local/bin/activate`
#
VIRTUAL_ENV="/home/$USER/venv/$1"
export VIRTUAL_ENV
ACT_SCRIPT='source $VIRTUAL_ENV/bin/activate'
eval "$ACT_SCRIPT"

I typically keep all my venvs in the same directory, rather than within the projects themselves. This script helps me swap between them quickly without having to remember any paths or do any directory voodoo. Just source activate data_science or source activate flask_project from anywhere

Uses /home/$USER/venv instead of ~/venv in case file is saved as root

Running deactivate should exit the venv without any additional config
