To add to Lutger's message. I believe it is sh that is required by all
Posix systems, or at least an equivalent. Similarly I think vi is also
a requirement.
In all likelyhood you probably used a Bash specific feature, but
usually everyone has bash even if they use zsh... Though Ubuntu/Debian
has started pointing /bin/sh to dash which is complaint with posix...
Ok. I'll see I can use only sh.
FWIW, /bin/sh is usually a symlink to bash, and it makes bash behave like
the original Bourne Shell.
I typically find /bin/sh features to be enough for implementing most
scripts.
A good reference (if you don't have it) is Unix in a nutshell, probably my
most used textbook.
