I want to be able to read a text file every 10 minutes or so. Since
the file can get pretty large over time, I want to pick up where I
left off earlier. Is this possible using Perl ?

The tell() function can tell you the current position in a file and
the function seek will take you to a given position in a file. Then
you just need to store this offset somewhere.

If you have a long running perl process which reads to the end of
file, waits ten minutes and want to read further, you can use seek to
clear the end of file-state without reopening the file or without
using tell. $fh->clearerr() should do the same.

perldoc -f sleep
perldoc -q timeout

perldoc -f seek

You could also take a look at "perldoc -q tail"
