Question

I’m trying to make a server manager, but I need to grab the process IDs and Commands of some processes.

For example:

 ps ax | grep ./skulltag
 4760 pts/2    Tl     0:02 ./skulltag-server
 4793 pts/2    Tl     0:01 ./skulltag-server
 4956 pts/2    Tl     0:01 ./skulltag-server -port 13000
 4958 pts/2    Tl     0:26 ./skulltag-server -port 13001

How would I get it to only return the process, only return the command (./skulltag-server) or both? Thanks.

Answer 1

You can pipe to awk to select which field to output

E.g. ps ax | grep ./skulltag | awk '{ print $1 }' will print the first column (pid)

Note that you may also want to look into using the -o option to ps to modify its output
