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 run a command with mise's tools and environment without modifying the shell session, or to run ad-hoc commands with tools that are not in the config.

Tools are loaded from mise.toml and can be overridden with <TOOL@VERSION> args. Only the tools you name are overridden: if mise.toml includes node = "20" and you run mise exec python@3.11, node@20 is still loaded.

The "--" separates tools from the command to pass along to the subprocess.

Arguments

• [TOOL@VERSION]… — Tool(s) to load e.g.: node@20 python@3.10
• [-- COMMAND]… — Command string to execute (same as --command)

Flags

• -c --command <COMMAND> — Command string to execute

• -j --jobs <JOBS> — Number of jobs to run in parallel Values below 1 are treated as 1 Defaults to the jobs setting

  Environment Variable: MISE_JOBS

• --allow-env <VAR> — Allow specific env var through (implies --deny-env for everything else) Supports wildcards, e.g. --allow-env='MYAPP_*'

• --allow-net <HOST> — Allow network to specific host (implies --deny-net for everything else) macOS only in v1; on Linux falls back to allowing all network

• --allow-read <PATH> — Allow reads from specific path (implies --deny-read for everything else)

• --allow-write <PATH> — Allow writes to specific path (implies --deny-write for everything else)

• --deny-all — Block reads, writes, network, and env vars

• --deny-env — Block env var inheritance (only PATH, HOME, USER, SHELL, TERM, LANG pass through)

• --deny-net — Block all network access

• --deny-read — Block filesystem reads (system libs and tool dirs still accessible)

• --deny-write — Block all filesystem writes

• --fresh-env — Bypass the environment cache and recompute the environment

• --no-deps — Skip automatic dependency preparation

• --raw — Connect backend install command stdin/stdout/stderr directly to the terminal. Implies --jobs=1

• -h --help — Print help

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
