I'll have a look at the package, thanks for the tip. What I wanted overall was to have perl cause a system beep, repeatedly, until you came and hit a key after a hardcoded process related to the nohup file had exited.
My code follows, not sure if perl would allow me to ween from ps and awk or not. Im getting a ton of Spawned Process XXXXXX messages, which even if i can surpress those, it now feels as if its not the most efficient manner =) #! /usr/local/bin/perl use Term::ReadKey; use IO::Handle; my $key; my $nohupfile=$ARGV[0]; print "ptail v1.0\n\n"; die "\n***** usage: ptail <filename>\n\n" unless defined ($ARGV[0]); open (NOHUPFILE, $nohupfile) or die "\ncan't open $nohupfile: $!\n\n"; seek (NOHUPFILE,50,2); my $CMD= qq { ps -a | awk '{ if (\$4=="adpatch") print \$1 }' | tail -1 }; #hardcoded to look for any Oracle adpatch binary process. print "DEBUG: CMD: $CMD\n"; #exit; my $process=`$CMD`; if (length($process) == 0) { print "ERROR: Patching Process not found.\n"; exit; } print "DEBUG: Process: $process\n"; #exit; my $doneflag=0; while (!$key) { $key=ReadKey(-1); if ($key) { last; } while (<NOHUPFILE>) { print } if (!$key) { sleep 2; $CMD= 'ps -a | awk \'{ print $1 }\'' ; if ((grep /$process/, `$CMD`) < 1) { print "[[ Patching Complete ]]"; print ""; #insert ^V^G here sleep 2; } } else { last; } NOHUPFILE->clearerr(); } ----- Original Message ----- From: "Thomas, Mark - BLS CTR" <[EMAIL PROTECTED]> Date: Tuesday, February 22, 2005 9:43 am Subject: RE: tail a file [was: subscriber] > The default setting of File::Tail behaves the way you want. > Perhaps that is > an easier solution. > _______________________________________________ Perl-Unix-Users mailing list Perl-Unix-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
