Hi

I would like to scan the syslog file continously and page me the new line as and when a new line is added to the syslog file.Does anybody have a perl script for doing this ?

regards
Hrishy

You could use File::Tail (Perl extension for reading from continously updated files) for the tail -f.

Whithout any modul you can do the following:

open(LF, "tail -f $LOGFILE |") || die "no logfile !";
while () {
.
.
}

So you open the $LOGFILE with "tail -f", and
the "|" send it into a pipe.
Inside the "while" you can get the new lines
and work with them.
