Command Line Options

just supports a number of useful command line options for listing, dumping, and debugging recipes and variables:

$ just --list
Available recipes:
  js
  perl
  polyglot
  python
  ruby
$ just --show perl
perl:
  #!/usr/bin/env perl
  print "Larry Wall says Hi!\n";
$ just --show polyglot
polyglot: python js perl sh ruby

Some command-line options can be set with environment variables. For example:

$ export JUST_UNSTABLE=1
$ just

Is equivalent to:

$ just --unstable

Consult just --help to see which options can be set from environment variables.
