Results from a system call
Is it possible to put the results from a system call into a variable? I tried:
$variable = system("fgrep date $file");
print "VARIABLE: $variable\n";
The results from the system call print to STDOUT, but when I print $variable, it prints:
VARIABLE: 0
I assume that the system call it returning 0 to mean that the command was successful, but is there a way to put the results from that system call into a variable?
Thank you in advance.
