I wish to suppress the general information for the top command
using a top parameter.
By general information I mean the below stuff :
top - 09:35:05 up 3:26, 2 users, load average: 0.29, 0.22, 0.21
Tasks: 1 total, 0 running, 1 sleeping, 0 stopped, 0 zombie
Cpu(s): 2.3%us, 0.7%sy, 0.0%ni, 96.3%id, 0.8%wa, 0.0%hi, 0.0%si, 0.0%st
Mem: 3840932k total, 2687880k used, 1153052k free, 88380k buffers
Swap: 3998716k total, 0k used, 3998716k free, 987076k cached
What I do not wish to do is :
top -u user | grep process_name
or
top -bp $(pgrep process_name) | do_something
How can I achieve this?
Note: I am on Ubuntu 12.04 and top version is 3.2.8.
It's known as the "Summary Area" and i don't think there is a way at top initialization to disable those.
But while top is running, you can disable those by pressing l, t, m.
From man top:
Summary-Area-defaults
'l' - Load Avg/Uptime On (thus program name)
't' - Task/Cpu states On (1+1 lines, see '1')
'm' - Mem/Swap usage On (2 lines worth)
'1' - Single Cpu On (thus 1 line if smp)
