exit value of system versus back quotes

[shrajan]

Hi,
I have a script where I am running a command using system and then
using back quotes and I getting different exit status in both cases.
This only happens on linux Redhat 4.0 EL.

`opcmon OSSPI-syslogproc_2=0`;
print "value1 = $?\n";
system("opcmon OSSPIlogproc_2=0");
print "value2 = $?\n";

value1 is -1 and value2 is printed as 0.
Thanks,
Shiju,

No you're not.

Which is not surprising when you run two different commands.

This only happens on linux Redhat 4.0 EL.

`opcmon OSSPI-syslogproc_2=0`;
"OSSPI-syslogproc"

print "value1 = $?\n";
system("opcmon OSSPIlogproc_2=0");
"OSSPllogproc"

print "value2 = $?\n";

value1 is -1 and value2 is printed as 0.

Why are you expecting anything different?
