my @array =grep {-d "$directory\/$_"} readdir <LS2>;
gives me this error::
Type of arg 1 to readdir must be HANDLE (not <HANDLE>) at ./subdirs.pl line 30, near "<LS2>;" Execution of ./subdirs.pl aborted due to compilation errors.
The expression "readdir <LS2>;" is the same as "readdir readline LS2;". Whenever you see a FILEHANDLE delimited by < and > it the same as using readline with that FILEHANDLE.
perldoc -f readline
