The use of "echo -e" is not portable and not specified by POSIX. dash does not support any options except "-n", and so this script will not work on operating systems which use that as /bin/sh. Fortunately, the solution is easy: switch to printf(1), which is specified by POSIX and allows the escape sequences we want to use. This will allow the script to work with any POSIX shell.

It was reported in 2014 and has gone unfixed since then, so possibly this script is seeing relatively little use on Debian and Ubuntu. I have not CC'd any of the authors because nobody's touched this in over 9 years and none of those people are still active.
