[Chicago-talk] return value of failed system call

[Andy_Bach at wiwb.uscourts.gov]

my $result = system("yum -y install NotA_real_package.hah-ha");

> and $result comes back as "0" just as it does when I successfully 
install a package. I am using CentOS. 

Because yum is saying - "I didn't find that, but everything worked as 
expected otherwise"
# yum -y install NotA_real_package.hah-ha
Loaded plugins: downloadonly, rhnplugin, security
Setting up Install Process
No package NotA_real_package.hah-ha available.
Nothing to do
# echo $?
0

"info" though ...
# yum info NotA_real_package.hah-ha
Loaded plugins: downloadonly, rhnplugin, security
Error: No matching Packages to list
# echo $?
1
