From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I had several tests at the beginning of the script. These tests define the "low-level" functions based the capability of the shell. To test new features I "simply" ran all the necessary commands on the test environments (bash, busybox, toybox+mksh).
The script would error out if some necessary capability was missing from the host system. It also had a feature to switch shell if it found a better one (preferring busybox and its internal tools).
Yeah... It was tedious process. It was one of those "I'll write a simple script. So simple that it'll work on almost every posixy shell."... rest is history.
