### Configuring the Shell
|
||||||
|
|
||||||
|
There are a number of ways to configure the shell for linewise recipes, which are the default when a recipe does not start with a `#!` shebang. Their precedence, from highest to lowest, is:
|
||||||
|
|
||||||
|
1. The `--shell` and `--shell-arg` command line options. Passing either of these will cause `just` to ignore any settings in the current justfile.
|
||||||
|
2. `set windows-shell := [...]`
|
||||||
|
3. `set windows-powershell` (deprecated)
|
||||||
|
4. `set shell := [...]`
|
||||||
|
|
||||||
|
Since `set windows-shell` has higher precedence than `set shell`, you can use `set windows-shell` to pick a shell on Windows, and `set shell` to pick a shell for all other platforms.
