Most people use ps in its simpler form (ps -ef / ps aux) and use (e)grep to get the details they want.
ps has however a ton of options that can be used to influence what is shown and how this info is shown.
This, for example, is the ps ... | sed ....
shown above by only using ps:
ps -C vsftpd -o user,pid,%cpu,%mem,vsize,rss,tty,stat,start_time,time,cmd
The -c name
specifies the process that you want to see and the -o ...... line determines what you want to see about this process.
Have a look at the man page (STANDARD FORMAT SPECIFIERS
) to get a list of what it is you can specify to see.
