Is there any command in linux to figure out , given a process, which processor the process is running? I am interested in figuring out the CPU busy and CPU idle time of that processor.

I have 10.04 installed on my Laptop (Dell Latitude D630 with the Nvidia video upgrade). This was a clean install to a hard drive that I let it totally erase and use as it saw fit. I am using the Nvidia driver marked as "current" in the hardware driver settings.
When my laptop screen dims due to inactivity, such as not used for 5 mins or so, it will prompt me for a password to log back in. No big deal. However, when it resumes from this state it is SLOW!! I go to system monitor and see that the process "Compiz" is burning up both of my cores at about 70% or HIGHER. It's not using a significant amount of memory which is strange.From what I have been able to gather Compiz has some responsibilty for the GUI and killing the process to attempt to restart it is a "bad idea".
I have just created a usb boot disk so that I can install Fedora 14.I used the following which was successfully. However, I am left wondering what does the bs parameter actually does. I know it mean bytes and copies these at a time. But how do I know what to set it to?dd if=F14-Live-i686.iso of=/dev/sdb bs=8MIn the above example it is set to 8MB. However could I set this to any value that I want?

anyway i need to take the average of all rows with the same 1st number(key). i.e.
1, 3, 4.66, 5.66, 5
2, 3.5, 4.5, 5, 3.5
I know this is something awk/sed would be great for, i just dont have enough experience with them to accomplish it, Also, what about averaging those columns together? so, after I output this to a file, id like to get another like:
1, 4.58
1, 4.125
The number of colums to add might not always be 4 either. EDIT: this might be easier to do in gnuplot, so I mainly just need an answer to the first part.
I'm constantly going 'cd ../../../../'. Is there a command/alias that could let me go 'cmd 4' and I'd be taken back 4 directories?

I need to organise an external HDD such that there is no more than 500 folders on it.
Ubuntu's "Properties" pane shows only the file count, not the folder count.
Is there a simple CLI line that will tell me the number of subdirectories?

View 9 Replies View RelatedI use the system command route from a process (using the system() call). For security reasons the process does not have root privilege and for some reason I cannot use ioctl() either. I tried to set the capabilities of the process to NET_ADMIN and SYS_ADMIN but the route command still failed due to insufficient permissions.
What are the capabilities that I need to set for route to be successful?

View 1 Replies View RelatedI have a script that calls other scripts/commands which may or may not spawn other process. From my understanding, when I do a ps -ef, the highest numbered process ID is supposed to be the parent ID of all the other related child processes, is this correct? In most or all circumstances, I do a ps -ef | grep <processid> of my script and anything that spawns off that process IDs I assumed are the child processes of my script. If I want to terminate my script and all other child processes, then I kill the parent ID which is the highest numbered PID and this will subsequently kill all other child process IDs, is this correct?
Now, my question is whether there is any quick way of showing what are the child processes of a parent ID instead of what am currently doing now which is visually checking which one is the parent ID and "assuming" that the highest numbered PID is the parent ID of all the other processes. Below is a sample output of running ps -ef | grep exp | grep -v grep. I assume from the output below that the parent process/ID is PID 11322, is that correct?
