Usage: trim filename x y

  If filename's length exceeds x bytes, then as many as
  y lines are removed from the start of the text file. Exit codes:

0=OK, 1=can't open file, 2=can't create temp, 3=can't write to file,
255=syntax. Information messages are sent to stdout (1). Error messages
to stderr (2).

--------------

I wrote Trim because I needed a way to monitor and control the sizes
of logfiles. You can put Trim in a script so that it automatically
does this, for example:

trim access_log 1000000 100

This command will examine access_log to see if its length is greater
than 1000000 bytes. If the file's length exceeds the limit, then Trim
will remove 100 lines from the start of the text file. If the file
has less than 100 lines in it, then the file will cleared.

If you are running Trim in a script, you may want to suppress normal
output but keep an eye out for errors. You can accomplish this with:

trim filename x y 1>null

This redirects stdout (1) to null, leaving stderr active. You can also
redirect errors to a file:

trim filename x y 2>error.log

These stdout/stderr redirections work with Windows NT but may not work
with Win95/98/2000.
