[Doctor Q]

$# is the number of arguments passed.

For example, if myscript contains the line

echo $#

then you'd get this:

myscript
0
myscript all
1
myscript all your
2
myscript all your base
3
myscript all your base are
4

You can use a test like this:

[ $# -le 2 ] && exit 0

to exit if there are fewer than two arguments.
