The builtins depend on the used shell, for Kornshell for example you can
find the information in the manpage online
http://www.cs.princeton.edu/~jlk/kor...doc/man93.html
or for bash with man bash. Though careful about portability; even most
modern shells have a large common subset you may occasionally want
to restrict to the POSIX subset. (The above ${...%...} is POSIX.) Surely
the man pages are a good source to get an overview of the shell features.
