Commandline: Which programs are using network connection

Posted on 29. August 2017 Comments

lsof -P -i -n | cut -f 1 -d " " | uniq

lsof – list open files
-P list port numbers instead of service names
-i list all network files
-n IP addresses instead of host names

cut – cut output
-f specifies fields, separated in the input by the field delimiter character (-d)
-d delimiter

uniq – filters out repeated lines

Flattr this!
