execline is a (non-interactive) scripting language, like sh ; but its syntax is quite different from a traditional shell syntax. The execlineb program is meant to be used as an interpreter for a text file; the other commands are essentially useful inside an execlineb script.
execline is as powerful as a shell: it features conditional loops, getopt-style option handling, filename globbing, and more. Meanwhile, its syntax is far more logic and predictable than the shell's syntax, and has no security issues.
execline is free software. It is available under the ISC license.

Before version 22.214.171.124, execline used the slashpackage convention by default. This is not the case anymore; nevertheless, the examples in this documentation still use #!/command/execlineb as their shebang line, and assume that the execline binaries are available in /command. Adapt them according to your installation: the shebang lines for your system might be something like #!/bin/execlineb, or #!/usr/bin/execlineb, or #!/usr/local/bin/execlineb, or something else entirely.
All these commands exit 111 if they encounter a temporary error, and 100 if they encounter a permanent error - such as a misuse. They exit 127 if they're trying to execute into a program and cannot find it, and 126 if they fail to execute into a program for another reason.
