If you have a script (e.g. foo.sh) and you wish to pass arguments to the
script, your command line should look like "foo.sh arg1 arg2 arg3..." The
number of arguments will be correct and you will be able to access them as
${1}, ${2}, etc. Also, you may want to read up on the getopts command as a
way to process command line arguments.
Technically, the {}'s are not needed. You can access them with $1, $2,
etc. Most special characters sever as delimiters too so you can refer to
them as "This the $1 parameter" or even "/path/to/$1/dir". But if you
wanted to do something like this - "This is the ${1}parameter" or even
"/path/to/$1.save/dir" but not "/path/to/$1save/dir" you'd need the {}
(i.e. "/path/to/${1}save/dir" because otherwise the shell would be
looking for "1save" as an env variable name.
