I don't know that there are single commands ("a command") to do exactly what you need.
So it might be that you need to find the command that gets generally what you're looking for, and then use other commands, like awk, sed, cut and grep, etc. to extract the exact information you need.
Which version of what Linux are you using, and what shell?
Additionally, I am sure you must have used the ps command? With the right options, that can also show the date when a process starteed. Here's a link to the man page: ps(1).
There's PERL, which is a "practical extraction and reporting language". It can be a bit overwhelming for newbies, so if you need to "extract" anything from ps or any of the network commands, I would suggest using awk!
1 : Finding the first process: once youve mastered a bit ps command it should not be too difficult to find the requested... it must be PID 0 or 1 or...
You are to look at the man pages for ps syntax differ between OS (e.g ps ax v.s. ps -ef...)
Here is a tip: you can find a man page by entering
but this assumes that you know which command you look for. You can also search the man database for keywords by using the "-k" switch.
will display a list of all articles involving "foo". You can then start to read these articles one by one. Also useful: at the end of each man page there is usually a paragraph labeled "SEE ALSO". I suggest you do exactly this.
For instance:
Quote:
5. And a command showing the IP/MAC mappings of each of the LAN connected computers
You sure know the network protocol which maps layer-2 (MAC) addresses to layer-3 (IP) addresses, don't you? Now, enter this as a keyword in a "man" search and you might find some useful references.
