Subject: [PBML] what is "-d"
I hope everyone's had a nice weekend.
I was looking through a perl program and found this line inside a
return unless (-d '/usr/local/www/docs/INSERTURL.com/tpl'); #don't send
the INSERTURL is where the actual URL is.
Can anyone explain what this does? It seems like perhaps it stops the
subroutine unless something is true, but I don't understand the "-d".
