How does top name the command that is being executed I mean the last field of the command.

How does it name the command (like eclipse,java etc.) , are there any other commands which show the same not like ps command which shows the complete process command( last field of ps /bin/shared/eclipse ).

I have already gone through this question but it didn't explain it though.

  • No, it depends on the option you use with `ps`. Anyway, what you're looking for highly depends on the OS... There is no generic technic to extract processes info. On some Unixes there is a special procfs that uniformize the parsing of the process table... – Jean-Baptiste Yunès Feb 05 '15 at 20:53
  • Thanks Jean.. So you mean to say that top gets some if its info from process table and some from /proc ? – user2081934 Feb 05 '15 at 23:55
  • Exactly there is no other way if you want to have some precise info about processes. – Jean-Baptiste Yunès Feb 06 '15 at 06:58
