history

Project history and usage

shmux, the shell multiplexor, runs the same command on many hosts in parallel. It creates a child process per target and can connect through ssh, rsh, or a local shell.

Project history

shmux was created to execute one command concurrently on many targets while retaining readable, controllable output. The official repository preserves a C and shell implementation, a roff manual, and an Autotools build system.

The official GitHub project published version 1.0.3 in January 2019.

Adoption history

The supplied package metadata records distribution through Homebrew and MacPorts. Its workflow belongs to the long-established Unix cluster-administration family of fan-out command tools rather than to a hosted orchestration service.

How it is used

Interactive users receive formatted, optionally grouped output, real-time status, pause and resume controls, and configurable stopping behavior on errors. Scripts can use saved output and exit-code files for later processing.

Authentication is delegated to the selected remote-shell transport; the project does not document a shmux-specific credentials file.

Why package nerds care

shmux is representative of pre-cloud, shell-native fleet administration: a small C utility that fans a command out over existing remote-shell transports. Package enthusiasts care about its scriptable result files, interactive error controls, and place alongside tools such as pdsh and pssh.

Timeline

2019: The official GitHub project released version 1.0.3.

Related projects

The official README identifies dsh, fanout, mussh, pdsh, pssh, tentakel, and other parallel remote-shell tools as related work.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
