Im trying to list the cpu usage of all process that have a cpu usage of 10% or more. Im not interested in the lower usages. Im using the top command and can get a list of all the cpu usage for all the process but cant only get the processes with 10% or more. I'd want these processes sent to a new file. Would I be able to cat the cpu usages and PID into a file?

I would like to recursively list the contents of these 20 sub-directories. How do I do that ? I would like to do this in Solaris 10 and Linux(RHEL 5.x).

Code:

View 2 Replies View RelatedI have a problem that I'm not sure how best to debug. About every other time when I boot my system, I get a condition where listing the files in /root locks up that xterm session.This can be cleared by opening another xterm window and killing the listing command. This happens on "ls -a", "find", "tar" and I think "stat" also. The locked up xterm echo's chararcters but does not respond to any control sequences. This is new with FC11.This has only been seen to happen for root. And once a system is booted with this problem it seems to persist until you get it booted without the problem.

View 1 Replies View RelatedI regularly use 'df -h' to check usage on each of my primary directories and mount points.
I'm currently somewhat confused by disk usage within my filesystem, so I'd like to do the following:
Display directory size of all, or say, the 10 largest, subdirectories to a specified directory. So, if I passed the root (/) directory, output would list the subdirectory of / with the largest disk usage first and its associated disk usage listed in human readable format (either M or G suffix as appropriate), followed by the subdirectory and usage for the second largest directory and so on.
Can anyone suggest a command or series of commands to do this?
When at the console, what is the command (if there is one) to determine memory usage (used/free) on the hard drive that is being used for one's OS?

Changing the file extension is easy since there are lot of examples for this.
But now I want to rename my files like this:
'somePrefix_blablabla.ext' --> '0_blablabla.ext'
'somePrefix_blablablablabla.ext' --> '0_blablablablabla.ext'
I DON'T want an incrementation, just the leading prefix '0_'
correct perl expression syntax for this?
I presume that if this is possible it would need to be done as root (or as a user who shares root's UID of 0).How can a process be launched so that it does not show up in a ps aux or ps ef or top listing if the command is run by non-root?Is this even possible?The distributions I typically run are RHEL/CentOS and Ubuntu - so if there is a distro-specific answer, that's ok, too.
View 1 Replies View RelatedIs it possible for a non-root user to hide themselves from the output of who/w, so that they can be logged in without other users seeing it? I think that the file /var/run/utmp might have something to do with this, but it's not writeable by non-root users (permission 644). I'm fairly certain that this can be done by a non-privileged user (because someone told me that they were able to do so), but I don't know how they did it and can't ask them right now.
View 1 Replies View RelatedI can't seem to find a way to do this, so maybe it's not actually possible, but I was wondering if there was a way to list all files that link to a file.
For example.
touch a
ln a b
ln a c
I want to find out what files link to a (not symlinks, mind you), assuming that this is more complicated (they are spread around to different directories).
I kind of understand about the filesystem storing links in one area and data in another, so I understand it probably takes more work to find a link from a file location than the other way around.
