Using Geektool I want to output some of the stats that top spits out on my desktop, but not all of them. Rather than calling top | grep "Line_I_want_to_spit_out" for each different line I want it to show(resulting in 5-6 separate calls to top), is it possible to just call top once and select the lines I want it to show? (ex. show Processes, CPU usage, PhysMem, and the top 10 processes ordered by cpu)

If you're not averse to using grep, you can do something like top | grep -E "Line1|Line2|etc"

That definitely works for the information on top. Do you know if it's possible to also have it show the top 10 processes ordered by cpu usage (top -n10 -o-CPU -stats cpu,command)? Or would that have to be a second call to top? – flapjacks – 2013-02-13T21:18:29.740

Use:
ps -arcwwwxo "command %cpu %mem" | grep -v grep | head -9

1While this might answer the question it might be good to break out and explain the separate parts to educate as well as answer the question. – Mokubai – 2016-12-13T07:22:07.247
Which lines do you want to display? – Dennis – 2013-02-13T20:55:55.123
Processes, CPU usage, PhysMem, Networks and 10 processes ordered by cpu usage – flapjacks – 2013-02-13T21:15:59.740
On the command line,
top | grep PATTERNkeeps refreshing, rather than just producing a single static output. Is this what you want? (I'm not familiar with Geektool.) – Dennis – 2013-02-13T21:22:13.080
