Hi,
At reaching a certain point in my perl program, I need to run a process
( say XYZ ) using SYSTEM command. The result file that this process
would produce will be result.<process_id>. I will have to wait until
this result file is produced & then proceed extracting certain things
from this file.
I am implementing this as :
foreach $check (@run) {
$pid=fork;
if($pid == 0) {
exec("XYZ -a $check");
}else{
$pid1=wait;
}
if ( -e "result.$pid1") {
## perform operations on the file result.$pid1##
}
system("rm result.$pid1");
}
This seems to be performing inconsistently. I am seeing this working
properly sometimes & not working properly sometimes. This works on
certain workstations & doesn't work on certain workstations.
Why is this inconsistency ??
I would be satisfied if I am given a clean/consistent/straight forward
implementation methodology for my purpose.
Thanks,
Ravi
