Get all CPU usage using TOP command

Im trying to get cpu/mem usage from one of processes running on my machine. I'm using command:

top -b -p <PID> > some_file.txt

but it's giving me only the current utilization of one CPU. I know that in interactive mode I can use 1 to display all of my cpu's, but is there a way to achieve that in batch mode?

If you do "$man top" you can see " t option" for 4 way toggle. Use the option.

Steps to display cpu usage bar. 1. run top command 2. press 1 to list the cpu usage. 3. press "t" twice to display cpu usage bar.

Ok, this was kind of fast :) This issue can be resolved in following steps:

start top in interactive mode (form me, as I wanted to get the correct process to be shown - top -p <PID>
press 1 to display all cpu's utilization
press W to save the configuration

Now, as I found, top in batch mode uses file .toprc as a configuration file. When You save your configuration in interactive mode, You can use this file later on. So now, when it is saved, You can use top -b -p <PID> > some_file.txt and it will gather information about both cpu's utilization.
