sshp – parallel SSH executor

sshp manages multiple ssh processes and handles coalescing the output to the terminal.

By default, sshp will read a file of newline-separated hostnames or IPs and fork ssh subprocesses for them, redirecting the stdout and stderr streams of the child line-by-line to stdout of sshp itself.

This is free and open source software.

sshp has 3 modes of execution:

• line mode (line-by-line output, default).
• group mode (grouped by hostname output, -g).
• join mode (grouped by unique output, -j).

The first 2 modes, line and group, operate in largely the same way, differing only in how data is buffered from the child processes and printed to the screen. Line mode buffers the data line-by-line, whereas group mode does no buffering at all and prints the data once it is read from the child.

The last mode, join, however, buffers all of the data from all of the child processes and outputs once all processes have finished. Instead of grouping the output by host, it is grouped by the output itself to show which hosts had the same output.
