import
import
import
is a simple and fast module system for Bash and other Unix shells.
Inspired by Go's import command, you specify the URL of the shell script, and the import
function downloads the file and caches it locally, forever.
The code will never change from below your feet, and will continue to work offline.
👋
Example
https://git.io/fAWiz ← This URL contains a simple add
shell function:
add() {
expr "$1" + "$2"
}
You can use the import
function to download, cache, and use that function in your own script:
#!/usr/bin/env import
# The URL is downloaded once, cached forever, and then sourced
import "https://git.io/fAWiz"
add 20 22
# 42

Compatibility
The core import
function is fully POSIX-compliant, and maximum compatibility is the goal. import
is unit tested against the following shell implementations:
- ash - Almquist Shell (BusyBox
ash
and Debiandash
) - ksh - KornShell (
oksh
,mksh
andloksh
flavors) - zsh - Z Shell
- bash - GNU's Bourne Again Shell
