Perl Library For Mac System Calls
I am trying to run a Perl script that reads in filenames from stdin and calls du using a system command. When I run the du command on the commandline it works fine but when du is called in the perl script using system I get 'No such file or directory.' Perl system function spawns a child process and goes to the sleep mode, while the command is being executed. $^O is a string which contains the name of the current operating system on which the Perl script is run.

Port - sets the TCP or UDP port to connect to. Defaults to the first standard syslog port available on the system. The available mechanisms are: 'native' - use the native C functions from your syslog(3) library (added in Sys::Syslog 0.15).
