Wants to execute top for only 5 seconds

Narayandutt · 11-27-2006, 07:21 AM

hi friends,
As you all know when we give top commands it shows us top processes according to cpu usage. but the process is continuosly on untill we abort the top process by pressing 'control+c'. I wants this process
to automatically killed after 5 seconds. and I should come back to bash prompt. can anyone let Me know the script for it

Thanks

Why would you want to display top for 5 seconds then quit? If it's the load average or top processes you want, you should get this info from uptime or the ps command.

And the proper way to exit out of top is the letter q for quit.

You can specify update delay time and number of iterations using the -d and -n options. e.g.

Code:

top -d 5 -n 1

which would delay 5 seconds between iterations, and quit after 1. You could also get a "five second run" also using the opposite:

Code:

top -d 1 -n 5

...which would update once every second and terminate after 5 seconds.

All this is documented in more detail in the manual page. To read the manual page, you use the command:

Code:

man top
