Which shell does Line CLI use to run commands on Windows?

On Windows, Line runs commands with PowerShell. On macOS and Linux it uses sh.

What this means for you#

• Commands like npm test, cargo build or git status work the same.
• Unix-only commands (grep, sed, rm -rf) may not exist in PowerShell. Line normally uses its own built-in tools for reading, searching and editing files, so this rarely matters.
• If you want Line to use a specific command style, say so in your LINE.md: "We're on Windows; use PowerShell commands."

Plugins on Windows#

Plugins can define a separate command_windows for PowerShell. See Plugins.
