@ -5,6 +5,11 @@ Usage:
Specify --netstat as the first argument if the piped input is coming from netstat
Caveats:
- Use of multiple 'l' options is not supported on OSX (e.g. 'netstat -rlll')
- Use of the 'A' option is not supported on OSX when using the 'r' option (e.g. netstat -rA)
Compatibility:
'linux', 'darwin'
