Just Programmer's Manual

Fallback to parent justfiles

If a recipe is not found in a justfile and the fallback setting is set, just will look for justfiles in the parent directory and up, until it reaches the root directory. just will stop after it reaches a justfile in which the fallback setting is false or unset.

As an example, suppose the current directory contains this justfile:

set fallback
foo:
  echo foo

And the parent directory contains this justfile:

bar:
  echo bar

$ just bar
Trying ../justfile
echo bar
bar
