Other Handy File Commands

• Note that we have been using the relative path when writing to a file.  For example, the .. in

    open(PAGE, ">>../$bearcatID.html");
actually writes this file in the parent directory.  Since we are working in the .www/cgi-bin directory, this would put it in the .www directory.  You can put it in any reasonable directory you like.
• If you are generating an HTML page to be read by the public, you will want to change permissions on it.  You can do that in the script, with:

chmod (0755, "../mypage.html");
Where chmod is the function to change the permissions, 0755 is the permission you wish to grant, and "../mypage.html" is the name of the file, in this case, mypage.html in the parent directory.
• The book is full of additional file and directory functions.  For example:
• Renaming a file.
• Removing a file.
• Checking a file's status (good thing to do before you attempt to read it).
• Accessing a directory.
• Reading the contents of a directory.
• Changing the working directory.
• Creating a directory
• The book also has much more on string parsing.  This is considered one of the strengths of Perl.
