sprintf FORMAT, LIST Returns a string formatted by the usual printf conventions of the C library function sprintf. See below for more details and see sprintf(3) or printf(3) on your system for an explanation of the general principles. For example: # Format number with up to 8 leading zeroes $result = sprintf("%08d", $number); # Round number to 3 digits after decimal point $rounded = sprintf("%.3f", $number); Perl does its own sprintf formatting: it emulates the C function sprintf(3), but does

localtime EXPR localtime Converts a time as returned by the time function to a 9-element list with the time analyzed for the local time zone. Typically used as follows: # 0 1 2 3 4 5 6 7 8 ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time); All list elements are numeric and come straight out of the C `struct tm'. $sec , $min , and $hour are the seconds, minutes, and hours of the specified time. $mday

fileno FILEHANDLE Returns the file descriptor for a filehandle, or undefined if the filehandle is not open. If there is no real file descriptor at the OS level, as can happen with filehandles connected to memory objects via open with a reference for the third argument, -1 is returned. This is mainly useful for constructing bitmaps for select and low-level POSIX tty-handling operations. If FILEHANDLE is an expression, the value is taken as an indirect filehandle, generally its name. You can use

$" When an array or an array slice is interpolated into a double-quoted string or a similar context such as /.../ , its elements are separated by this value. Default is a space. For example, this: print "The array is: @array\n"; is equivalent to this: print "The array is: " . join($", @array) . "\n"; Mnemonic: works in double-quoted context.
