Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?

View 4 Replies View RelatedI am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.

But if i do copy with -p option then it shows right time stamp. Both machines are running with slight(minutes) different in time. Does this could be cause for this problem? The problem is happening while i do FTP from some other machines too.
We have a script that FTP files 3 times a day, once ant 02:30, 04:00 and 13:00. Once the process runs it puts a copy of the file sent in the processed folder. What I'm trying to do is check to see if the files are there and if not send an alert /email. The file names are IVF_20100806_*.150, PLAZ_ 20100806_*.151, TRAN_20100806_*.152 and TRAN_20100806_*.151

I'm rather new to linux, and I have a dedi server. I know how to browse, install, remove etc, all the basics needed to use it. I've installed flvtool2, memcoder and ffmpeg, and at the moment im converting avi files in to flv. Im then passing metadata using yamdi.
However, this process is very timely as im converting loads of avi files at a time.Im looking for a script, or a way where I can execute one command/script and which will convert all files in the directory I specify, then run those converted files through yamdi.Im guessing it would be some sort of loop, and then changing for each file?
when we do enter on a folder it take some time for loading the folder depending on the no of entries in the folder . If the folder has more entries it take more time to load and if less no of entries then correspondingly less time . the delay in loading the folder varies due to reading of the folder entries in advance . SO what i want to know is that what is the MAX no of entries read in advance while opening a folder in linux and also how can we calculate this
View 4 Replies View RelatedI'm trying to make a shell script that will list the 50 newest files in a directory with several subdirectories in. I've been trying with the find-command with no luck and now I've figured I should probably use ls. The problem is when I do "ls -lRt | head -50" it will do 1 directory at the time. It will not first make the full list and then sort it. This will display all items in first directory, sorted, then the newest directory will be sorted and displayed. So I figured I have to sort the whole process of ls before I limit the head. So this is where I am at now: ls -lRt | sort <something clever here> | head -50
Only doing a "|sort|" will sort it by name if I understand it right and I don't know how to solve it. Here's also my first attempt if that is of any interrest or help, this was limited by the change status time of files (so some lists got very large). These lists dit not get sorted by time and I could not find any way to do so.find $ftpDir -ctime $time -type f -print > $ftpFileLsAny help on this would be appreciated since I'm sort of stuck now. After reading manuals for all the options I can think of and still there's just a big blur in my head..

I have created some text executable files and put them on my desktop. In the way of background I created them in gedit. Then used chmod ugo+x (filename) to make them executable. One of them is a ping test to see if a printer is on. Text in file = ping 192.168.1.5. Others are to turn my laptop touchpad on and off. text in file = sudo modprobe -i psmouse.
I have 2 questions about executable text files:
- When I click on an executable text file it present a window with 4 options (Run in terminal, display, cancel, run). Can I set a parameter or do something else so it just runs in terminal? I know I can set an option in Nautilus to run them but when I select run nothing seems to happen. In addition I would want to set this option on a case by case basis not globally in Nautilus. If there is an option or flag where it would run this file in terminal I would use it on my printer ping test.
- When I click on these executable text files to turn my touchpad on and off, the text within the file uses the sudo command so that requires that I input my password. After I click on either of these files a window appears with the 4 options (Run in terminal, display, cancel, run). I select run in terminal, a terminal window opens and requests my password. Subsequent to inputting my password the file executes fine.
Is there a way to set a parameter or do something else so I don't need to not only select the run in terminal option from (run in terminal, display, cancel, run) but also not to enter my password?

I'd like to change a files modification date "only" without changing the time. I'm aware of the 'touch' command but is seems like it only allows changing both the date and time, and not one of them. Any ideas on an easy way to change a file's modification date without also changing its time? (I have a long list of files and thus would like to run one to command to change them all)Example: Change a file's (month) timestamp from "2010-09-23 11:59:23" to "2010-10-23 11:59:23"Background: I accidentally set the wrong month on my camera and ended up with all photos having a modification timestamp with the wrong month.
