Usage: Usage:
Specify --netstat as the first argument if the piped input is coming from netstat Specify --netstat as the first argument if the piped input is coming from netstat
Limitations:
incorrect parsing can occur when there is a space in the program_name field when using the -p option in netstat
Examples: Examples:
$ sudo netstat -apWn | jc --netstat -p $ sudo netstat -apWn | jc --netstat -p
