I imagine you could do something similar with bash (store the output to a variable, I guess) but I
wouldn't have the first clue how to do that. Or heck, the program would probably be simple enough
to write in C and then not worry (so much) about portability at all.
By the way, I wrote that last suggestion right after I'd woken up and I realize now that buffering
the data is unnescesary and maybe problematic. There's no reason I can see not to just read a
line, write a line, repeat. TI'm also thinking that there's also really no need to get anything
fancy from CPAN if you've already got tools that will dump out the nescesary data. Try this and
see if it works:
-----------------------------------------
#!/usr/bin/perl
$filename = $ARGV[0] ? $ARGV[0] : "log.txt";
$timestamp = localtime(time());
open(OUTFILE, ">>$filename") or die("Could not open file: $filename -- $!\n");
open(PDATA, "tail -f /dev/tty1a |tee |") or die ("Could not run command! -- $!\n");
print (OUTFILE "\n$timestamp\n---------------------------------------------\n");
while (<PDATA>)
{
print(OUTFILE "$_\n");
}
close(OUTFILE);
-----------------------------------------
Good luck! =:)
