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();
}
