Do you mean variables with built-in meanings? In which case, Thomas'
answer is the right one, though "help variables" gives you a short list
right in the shell.
If you want to know which variables are currently defined, the "set"
built-in command lists them. "help set" for a brief description or
consult the man page for all the details.
I use this shell procedure (defined in my .bashrc) to query local
variables:
vq () {
set | egrep -e "$1"
}
This has to be a shell procedure since by definition local variables are
not accessible in sub-shell and hence could not be displayed via a
conventional script.
And I use this counterpart to query environment variables:
eq () {
export | sed -n -e "/$1/ s/declare -x //p"
}
This one could be shell script, if you prefer.
