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. -- Andrew DeFaria Fear has its use but cowardice has none. - Mohandas Gandhi -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
