The system command executes a command and waits until that command completes.

      

# The basic syntax for the system function: $return_value = system(command);

# The $return_value will hold an integer. 
# You must divide this value by 256 to get the actual return value. By convention, a return value of 0 means OK.

#!/usr/bin/perl -w

$return_value = system("df");

print "System returned $return_value\n";
