General :: Find Description Of Mpstat Output?
Feb 19, 2010
I'm wondering where I can find description of mpstat output?.. I'm talking about the output of all available counters presented by mpstat. For instance:
Code:
$ mpstat -Au
Linux 2.6.31-19-generic (lenovo-S102) 02/19/10 _i686_(2 CPU)
17:32:15 CPU %usr %nice %sys %iowait %irq %soft %steal %guest %idle
17:32:15 all 36.00 0.18 10.39 0.73 0.08 0.03 0.00 0.00 52.60
17:32:15 0 36.81 0.15 11.58 1.14 0.16 0.04 0.00 0.00 50.11
17:32:15 1 35.26 0.22 9.31 0.34 0.00 0.02 0.00 0.00 54.86

I've got a system that is maxing out CPU. Running "mpstat -P ALL 3 5" shows the following.
Quote:
08:30:21 PM CPU %user %nice %sys %iowait %irq %soft %steal %idle intr/s
08:30:24 PM all 100.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 1001.00
08:30:24 PM 0 100.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 1001.00
[code]....
All 5 groups show the same. My first question is why would CPU0 be the only one with intr/s and the others do not? Info.The OS is RHEL 5.4 running as a VM on ESXi 4.1. Memory doesn't appear to be an issue, the system has 8 GB and its only using about 1.5 GB. Second question, I'm positive the process that is the problem is the tomcat process. Does anyone know a good way to see whats happening with a specific process?

I need to know what, for example, 'ttable' means and what is its syntax. This seems to be a state secret.

I am trying to automate an svnadmin dump command for a backup script, and I want to do something like this:
find /var/svn/* ( ! -name dir -prune ) -type d -exec svnadmin dump {} > {}.svn ;
This seems to work, in that it looks through each svn repository in /var/svn, and runs svnadmin dump on it.
However, the second {} in the exec command doesn't get substituted for the name of the directory being processed. It basically just results a single file named {}.svn.
I suspect that this is because the shell interprets > to end the find command, and it tries redirecting stdout from that command to the file named {}.svn.

I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one
Code:
And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.

I'm still trying to find out if my coby mp3 player will actually play mtv video files as is advertised.
ffmpeg -formats does list mtv but the only command I really ever used was one to convert a vid to an mp3 so I tried Code: ffmpeg -i test.mp4 -acodec copy output.mtv it returns Code: Unable to find a suitable output format for 'output.mtv' I can't find any mtv files online for purchase or free for that matter, so I know this is all pretty obscure but shouldn't there be a way to convert them since ffmpeg lists mtv format?

I am assigning "find" operation output to a variable. I also need to have error info / stderr if nothing is found in the same variable itself.
e.g.
a=`find . -name "hello.txt" -type f`
I do not want any temp files to be in between infact, redirection.

I'm testing some multi-plat java code and I'm getting a bit frustrated with the Linux tests. I need to run the command:
Code:
$ java -jar /home/developer/TCO/TabletComicOptimizer.jar <file> <args[]>
against all the files that match a specific criteria. I've tried various find syntax and I can't seem to get it right.
Normally I would just create a bash script and populate the results of find into an array and then just enumerate the collection but in this specific case I want to demonstrate this operation at the bash terminal.
I've tried things like:
Code:
~/TCO $ find . -type f -iname "*.cb[rz]" | xargs java -jar TabletComicOptimizer.jar {} 1200x1800 ;
Thinking that the {} is the substitution for each file returned by find but it's not working. How do I execute my java program against each result in the find operation?

I'm trying to copy all my photos from a windows drive to my Linux partition. So i created this small one-liner:
[code]...
the output from find has no space esc-character, i.e. /path/sub folder should be /path/sub folder.

I'm fairly new to writing bash scripts and haven't been able to find a an example of effectively using a the find command in a bash script.
I want to run some git commands on any sub directory that has a .git project in it. Getting to the directory is not my problem, its how to find them
What i want to do is execute
Code:
find -name .git
Then act on each response line that is printed out. E.G Navigate to the directory and run git status.
How do i use the output of the find command in the bash script?

Where can I find document re "how to read anova output"? Google found many of them. But seemingly non of them can explain to me following output:-
> tabA = c(5.67, 5.67, 5.55, 5.57)
> tabB = c(5.75, 5.47, 5.43, 5.45)
> tabC = c(4.74, 4.45, 4.65, 4.94)
> tabs = data.frame(tabA, tabB, tabC)
> tablets = stack(tabs)
> anova(lm(values ~ ind, data = tablets))
Code:

I want to find out my IP and I test this code from beej tutorial:
Code:
char hostname[128];
int i;
struct hostent *he;
struct in_addr **addr_list;
struct in_addr addr;
gethostname(hostname, sizeof hostname);
printf("My hostname: %s
", hostname);
he = gethostbyname(hostname);
if (he == NULL) { // do some error checking
herror("gethostbyname"); // herror(), NOT perror()
return 1;
} // print information about this host:
printf("Official name is: %s
", he->h_name);
printf("IP address: %s
", inet_ntoa(*(struct in_addr*)he->h_addr));
printf("All addresses: ");
addr_list = (struct in_addr **)he->h_addr_list;
for(i = 0; addr_list[i] != NULL; i++) {
printf("%s ", inet_ntoa(*addr_list[i]));
}
printf("
");
return 0;
But my output is this:
Code:
My hostname: vBx
gethostbyname: Unknown host
I heard that it works in windows, why isn't working in linux?

I want to scan a particular directory recursively and run a particular command with each file as input. For this I am using "find /dir/path". I dont want to write any long script containing loop on the output of "find". I want a single command which will allow me to run a command on each file of the "find" command output.

Back in the days of slow machines, displaying the package description during an install provided for some reading to break up the boredom (if one was inspired to sit there and watch it do the install). Now days, the descriptions just fly by, several a second most of the time (unless doing things manually). Do we really need this anymore? It's unreadable.
I'd rather see a list of packages being installed scroll by, one package name per line (with size info). Even that might get hard to read during the buzz of small packages being installed causing rapid scrolls.

What the right place to report errors in package descriptions ? There are more than two dozens categories mentioned on the openSUSE "reporting a bug" web page but none of them seem to fit. The packager of the concerned rpm is bugs.opensuse.org, no email printed out when launching rpm -qpi <package name>.

I have a personal webserver and webpage that makes my mp3 collection available to me on the network. It's more of a learning experience than anything else. Anyway there are two issues that I have found some information on, but I haven't been able to make sense of what I've found.
1. I would like directories to appear first and individual files to appear afterwards.
2. I would like for the name column width to match the longest name appearing in that column.
I am attaching a screenshot of the page for clarification.
