On my box,
Code:
ps -e | grep oracle Code:
0123456789012345678901234567890 8827 ? 0:00 oracle 6849 ? 0:00 oracle 25473 ? 0:12 oracle So I guess you could do something like... Code:
#!/usr/bin/perl
foreach (`ps -e | grep oracle | cut -c 17-21`) {
# strip the colon
s/://;
$sum = $_ + $sum;
}
print $sum;
