Perl Programming/Keywords/chmod

The chmod keyword
chmod changes the permissions of a LIST of files. The first LIST element must be numeric and should be an octal number, like 0755 chmod returns the number of files successfully changed.

If the operating system supports fchmod(2), a FILEHANDLE can also be part of the list. If this is not the case, an exception is raised.

Examples
Changes the access permission of file <tt>Boeing</tt> to read-write-execute for the user, to read-execute for the group of the user, and execute-only for the rest of users.
