You can directly invoke existing shell commands or scripts. But the language design of OpenResty OpsLang™ is more complete, with arrays, hashes etc. And the expressive ability is far superior to Shell.
You can emulate human beings performing various complicated operations directly on the terminal emulator. It also supports simultaneous control of multiple terminal windows like the screen/tmux tools. Furthermore, you can use the standard Perl-compatible regexes for streaming matching, streaming processing and other interactions with the virtual terminal output.
You can emulate human behaviour by logging in to a remote machine via ssh, and then performing a series of interactive operations on the remote machine.
The correct escape rules are automatically applied based on the context of the OpenResty OpsLang™ variable referenced in the shell command string, eradicating the possibility of a shell injection attack, while the OpenResty OpsLang™ code can remain beautiful and concise.
Similar to GNU make, each execution goal can describe its own dependency goals, but the target here does not directly correspond to the file on the file system. It is abstract, so that automatic dependency calculation and incremental building can be easily achieved.
It has a complete process log to view the inputs and outputs of each command, even those executed on a remote machine.
Currently supported operating systems include CentOS 6/7, RHEL 6/7/8, Ubuntu 14.04/16.04/18.04/19.04, Debian 8/9/10, Amazon Linux 2. Other system, like MacOS, will be supported later.
