@status issues

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I have a problem I cannot seem to find the answer for...

In the snippet below, this is what is returned with the system command:

sql: started
http: started
eventd: started
monitor: started
scheduler: started
server: started
watchdog: started
[download]

and if I print out @status, that is exactly what shows up. However, when I try to split the string after the system command, I am getting nothing but zeros... Any ideas?

:
:
$command = "dfm service list";
@status = system($command);
for ($x=0; $x<@status;$x++)
{
@sql_status = split /\s/, $status[$x];
}

system returns the exit status of the command it ran, not it's output. You want backticks (see `qx//` in perlop).	[reply] [d/l]

System returns the exit code from `$command`; it doesn't trap the command's output. To do that, you would use backticks or qx. emc Any New York City or Connecticut area jobs?

I've use something like `open($file, $file_to_execute." \|"); @text = <$file>; close $file;` [download] to catch the output of a system command. Well... I'm not sure this is the best way to acheive it, but it worked. - The_Hawk_1	[reply] [d/l]

I agree with the diagnoses, but I tend to use IPC::Open3 or IPC::Run3 to write to and read back from spawned processes. Actually I only use Open3 because it's core; otherwise where that isn't an issue I'd just use IPC::Run3 more often instead. __________________________________________________________________________________ ^M Free your mind!
