General :: How To Determine What File Tripped Up Tar Process
Feb 8, 2010
I am writing, well actually enhancing, a script to do a daily backup of important data on my PC to a second hard drive.I wish to tar my home directory to a single file - and will probably use gzip as well.So I decided to work out the correct tar syntax in a terminal first - here is what happened.I opened a terminal window.I cd to a directory not part of my home directory.I issued the command..Quote: tar -cvf mytar.tar /home/ken tar processed a bunch of files, the last being .netrc.I examined the tar file and it contains .netrc.The contents of .netrc are correct.I scrolled back through the list of files in the terminal window and do not see any error messages.I guess the question is... how do I determine what file tripped up the tar process?
I'd like to determine what process has ownership of a lock-file. The lock-files are simply a file with a specific name that has been created.So, how can I determine what process has a particular file open in Linux? Preferably a one-liner type or a particular Linux tool solution would be optimal.
I have Fedora Linux 13 64bit system. I use System Monitor to check which process is taking how much memory and cpu. Normally I have dozens of Chrome and Firefox windows open. The Processes tab shows which process is taking how much cpu/ram resources but I unfortunately there is no option like right click and make the window active that matches the PID (the one process that I have currently highlighted). Usually there is a chrome process taking up 30 or 40 percent of CPU while dozens other chrome processes taking much less cpu. I must determine which chrome window ( or any application which has multiple instances running) is taking that much CPU time.
I'm writing a C++ application and need to work with process substitution in the Bash shell. I'm trying to find a way to validate the paths passed as arguments to my program, some of which point to FIFO files created by process substitution.
Is there a shell (or C++) way that I can check if the system creates these files in /dev/fd or if they are created somewhere else?
Multiple dirs full of mp3s All strictly encoded with exactly the same parameters (CBR 128kbps, Joint-Stereo, etc) Is it possible to determine the total playing time (to within ~98% accuracy) by some formula based on the total file size? I say ~98% accurate since ID3 tags do consume a small amount of space.

In Linux, I'd like to know how to find the file(s) if any which as using a particular sector on the hard drive (ext2/3). There is a similar question here regarding Windows, however I need a Linux command line solution (this is a headless system).
if there's a tab-delimited file under /usr/desktop, how can I determine the number of rows and columns of the file in shell?And, if told the the 3rd column of the file contains only numerical values and all values in the 5th column are unique, how can I verify these in shell?
I had only Arch on an HDD.sda2 was "/".Now it's with Windows XP and sda2 is not a root any more but a container partition wich has sda{5,6,7} in it. I configured the dual boot and it works. It finds Arch and boots it, but not completely. Stops after some time and says: unable to determine the file system type of /dev/sda2. FSTAB is configured, sda{5,6,7} are on their places. So I can't boot Arch. XP boots correctly. What do I do with this error?Also it says: try adding rootfstype=your_filesystem_type to kernel command line.
I am writting a script to allow uploading of certain files. I want to limit the files by their filename and mime type, and by making sure the two match up.The first thing I need to do is make sure I've got all the mime types I need added. I have never done this before, but I understand that 'file' (which is what PHP's mime-type finding is based off of) uses magic databases that tell at which point in the file should have signatures of the filetype.
My trouble started when I was unable to determine the filetype of any of my video files. Currently, I have some .MOV and .MP4 files that I am using to test.
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process
I'm using CentOS 5.3. After booting up, where can I find the log file that contains if all services where successfully loaded or not? For example when computer boots you get a list of start services and they can be OK or FAILED. Is there a log file where this information is kept? I had a look in the following directory /var/log/ but not sure which one will contain the informaiton that I need.
Means I want to execute two executables one by one at the same time as shown below:execute1 execute2these are two executables. but the second one is executed after 1st one is closed is there any way two execute both.One way isgnome-terminal -e execute1execute2but here i want to hide the terminal window..........
I am running an Ubuntu(10.04) box and I am attempting to understand an error in a program.I don't have access to the source of this program, but I know it isn't working properly because it cannot find a particular file. I was wondering if it would be possible to monitor what file are accessed(more specifically denied access) by a process. My first idea was to breakpoint on fopen, but I didn't have any success.
If I forget to close a file, a socket or any other resource in a Linux process, and the the process terminates, will those resources be freed? Is there a difference if the process terminates normally or is killed?
Is there a bash command that I can use to determine the last file access time? I know about -atime option for the find command, but I want to doublecheck to make sure that I'm doing this correctly (the output when I use find -atime isn't what I expect).
I have the following which works but think there must be a easier one-liner way of doing this which involves not writing to a file but have failed to find something that works This is what I have:
As the title says, I'm looking for a program that will go through all images in a directory tree and determine if they're valid, if they've been corrupted, and (wishful thinking) if they have the wrong extension. Does anything like that exist?
