ever ever felt the need to say this) but "RTFM".
If you can't find this on your own you are either too lazy to warrant help, or too

It removes a trailing newline from a string:
chomp($line = );
This retrieves a line form an open filehandle and removes the trailing
newline (\n) from the end. Actually, it chomps off whatever $/ is set to,
but it is usually

It chops off the new line/return character when reading in a file. It's

\n is not the same as newline. Newline is (in ascii) character 0x0A.
\n is the end of line sequence for the target OS (LF on UNIX, CRLF on
Win32, CR on Mac, "END_OF_LINE" on some mythical OS, etc.). This has
bitten me in the past when I wrote code on a Linux box (\n = LF) and

Both should look at section 4.

There's really no need to be calling an external system command to get the
date. Perl has its own function, localtime(), and you can use the
POSIX::strftime() function to use date-like formatting instructions (the
%y and %m stuff).
