Command for processes

[tifoz]

I need a command for listing:
- number of current started processes,
- percentage CPU usage and
- cpu usage.

And save all that to some file. I found ps -u, but it has all kind of info that i dont need. Is it posibble to list only some info?
Thx.

% top > outputfile will work just fine too.
If you only need selected parts of the output, you can pipe it to awk(1), filter it with grep(1), edit it with sed(1), etc.

[cmd=]ps -ax | wc -l[/cmd]
and
[cmd=]vmstat[/cmd]

[cmd=]ps -ax | wc -l[/cmd]

minus head -1.

Also look at the -o options in ps(1), e.g.

ps -e -o pcpu,cpu,nice,state,cputime,args

or go all out with

ps -ajguxww -o pcpu,cpu,nice,state,cputime,args

Pick, choose, cut and sort at will.
