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 python@3.11; 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 python@3.10

[-- COMMAND]…

Flags

-c --command <C>

-j --jobs <JOBS>

Number of jobs to run in parallel [default: 4]

[experimental] Allow reads from specific path (implies --deny-read for everything else)

--allow-write… <PATH>

--deny-env

[experimental] Block env var inheritance (only PATH, HOME, USER, SHELL, TERM, LANG pass through)

--deny-net

[experimental] Block all network access

--deny-read

Examples:

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

# Specify command as a string:
$ mise exec node@20 python@3.11 --command "node -v && python -V"

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