mise exec

• Usage: mise exec [FLAGS] [TOOL@VERSION]… [-- COMMAND]…
• Aliases: x
• Source code: src/cli/exec.rs

Execute a command with tool(s) set

use this to avoid modifying the shell session or running ad-hoc commands with mise tools set.

Tools will be loaded from mise.toml, though they can be overridden with <RUNTIME> args Note that only the plugin specified will be overridden, so if a mise.toml file includes "node 20" but you run mise exec [email protected]; it will still load node@20.

The "--" separates runtimes from the commands to pass along to the subprocess.

Arguments

[TOOL@VERSION]…

Tool(s) to start e.g.: node@20 [email protected]

Flags

-c --command <C>

$ mise x node@20 -- node ./app.js     # shorter alias

# Specify command as a string:
$ mise exec node@20 [email protected] --command "node -v && python -V"

# Run a command in a different directory:
$ mise x -C /path/to/project node@20 -- node ./app.js
