a TUI utility for running multiple commands in parallel in easily switchable terminals
this app is heavily influenced by this TUI app: https://github.com/pvolok/mprocs
procmux allows the user to run multiple commands in parallel and makes it easy to view the output from each terminal session. Procmux configuration files can be included in projects that have a series of commonly used scripts / long-running processes. is intended to make it easy for newcomers to a project to browse and run necessary commands, while also reducing the need to manually spin up multiple terminal sessions for potentially long-running processes. Alternatively, personal or system-wide procmux config files can be defined for browsing/running snippets or commonly used shell scripts.
# if you use pipx
pipx install procmux
# if you use pip
pip install procmux
# if you use brew
brew tap napisani/procmux
brew install procmux
# standard usage
procmux --config /path/to/config.yaml
# with overriding config values
procmux --config /path/to/config.yaml --config-override /path/to/override-file.yamlHere is a procmux configuration example with ALL available configuration points.
Only the procs section is required, the rest of the properties have defaults predefined:

# these settings are used to control a signal server that can be used to send signals to procmux managed processes
# using another terminal or script. when the signal server is enabled, it will listen on the configured host and port
# for incoming signals. the signal server can be used to send signals to procmux managed processes without having procmux
# in focus.
# the procmux app can be used to send signals. Use any of the available procmux subcommands to send signals to the signal # server. IE: `procmux signal-stop --name 'long running print' --config /path/to/procmux.yaml`
