I know there's no direct way to do this. But can someone please suggest how I'm able to check the last user that opened a file?eg; vi test.txtThe last user that accessed test.txtI know last access/mod/change time can be displayed.Also lsof won't do anything as the script I'll be writing won't necessarily be running when the user has already closed the file

View 1 Replies View RelatedA non techie friend has helped an even less techie friend by contacting me by email to discuss an ailing laptop. A few emails were exchanged, with more details, and it was not looking good because it seemed that suddenly the CD drive was not responding, nor any USB devices, the wireless icon was gone, but Ubuntu still seemed to work (for now), with wired ethernet also working. I was struggling to think of what could be done, with the favourite routes of Live CD and Live USB apparently gone.
After a few more hours - another email: 'It's now working! After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'I see there is 'Disk Utility', and this would presumably fit the bill, but how does it do checks and repair when the damaged file system is being run, and is currently *mounted*? I thought utilities like fsck(?) could only be run on unmounted file systems? Have I misunderstood the disk utility fs check repair function? And anyway, what might be a good answer to my (nontechie) friend's question 'After so many reboots it checked disc for errors and repaired itself! Is there some way of doing that when needed anyway?'
For the record: (quote) It is a toshiba EA60-155 Model number PSA67E-00300C8J. He put in extra ram to install ubuntu. He thinks he may have deleted something! There is a 'trash' file on his USB drive with loads of stuff in it and he doesn't know how or why but because it won't now read the drive on her laptop we cant replace it! (end quote)
Last weekend i have increased the open file size (ulimit -n) for the application user id i have update the limits.conf file with necessary inputs restarted the service and the server as well, when i check the ulimit value for the specific user by switching user from other user it shows the new value (10240) but if i login directly using the application id the ulimit value shows as 1024 which one is the default one.

View 3 Replies View RelatedNormally I use 'netstat -an' to determine if a daemon is listening on a specific port. The excerpt of this command below doesn't list things like vnc (5900) on ipv4. It does however show it on ipv6. My issue is I want to know how to determine if it is indeed listening on ipv4 as would normally be seen with 0.0.0.0:5900. It would appear that all ipv4 ports are internally being redirected to ipv6. Of course this does simplify things, but it also leaves me unable to reliably determine the ipv4 listening status. How I can tell at a glance if a specific ipv4 port is being listened on? Is there a way to force netstat to list the ipv4 listens specifically?
Code:
art@eee1:/proc/sys/net/ipv6$ netstat -an

Running Maverick on my desktop. Had a strange happening sometime last night. I generally leave the computer on all the time. When I got up this morning, I saw that my computer had rebooted and it said that it wanted to check for disc errors and that there was a problem with /home It checked until about 70%, at which point it stopped advancing for a half hour, so I did a hard reboot and choose "I"gnore when I got the message again.
The computer booted fine. The disc manager gui seemed to think my hard drive is fine, but I didn't do the full, slow check. My hard drive is about a month old. When I opened "open office" there as a document to recover, indicating that the thing did in fact crash sometime last night. The next odd thing- my "Opera" web browser doesn't open the browser. The command it is calling up is "/usr/bin/opera %U" Doesn't do anything, nothing shows up as running in the status monitor. Rebooting doesn't change anything with opera, and I still get the request to do a disc scan and to try to fix errors.
I uninstalled and reinstalled the latest version of opera. I uninstalled that and installed an earlier version of opera. Then, I reinstalled the latest version of opera. In terminal, typing "opera" gives me the message: Could not initialize Opera. Typing "sudo opera" opens Opera. Using the icon to open opera still points to the same place, and still doesn't work. So, here are my questions:
1- How do I get a logfile of the crash that happened last night?
2- How do I figure out if there is a problem with the /home folder or a problem otherwise with my hard disc? How do I fix that?
3- Where would I point the "opera" icon so it opens normally?
4- Is there any way to recover the information that I previously had in Opera, such as passwords? I used "my opera" to recover my latest bookmarks, but that doesn't save passwords. I'm thinking maybe those files are still around, even though I uninstalled and reinstalled opera.
I'm running Fedora 11 64bit on an Acer Aspire 3935, dual boot with Windows Vista. I installed three days ago and the system is supposedly fully updated. While doing some routine configuring I noticed that I am unable to access the Preference window of File Management.
I want to check the box for 'always open in browser windows', but therefore I need the Preference window. When I try to access through System > Preferences > File Management, it says starting for a few seconds and then nothing. When I try to access through Computer > Edit > Preferences, the window crashes and disappears. I suppose there are other ways to change that setting, but in any case I'd like to get the general problem solved, not only the setting changed.

For example the user entered: 192.168.0.1 so its true this is an ip address, if it doesn't look like an ip address then is false And second example, the user entered: 255.255.255.0 so the script returns true, and if its not a netmask the script returns false.
View 6 Replies View Relatedmy partitioning layout was as follows
Vista Recovery
Windows 7
GRUB
Extended
-->Fedora 12 (ext4)
so, I shrunk my recovery in Windows 7 successfully, and booted into my Fedora 12 live cd to run Gparted, and move the partitions so that the free space could go towards fedora, I did such, and then I couldn't expand the partition to my dismay. Next, I woke up this morning, tried to boot to fedora to run SSH, grub loaded, but when I tried to boot fedora, I got the "File system check failed" error, and when I tried 7, it just went to a blank screen with a single "_" in the top left-hand corner.
I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

echo "Please enter URL:"
read URL
cd testdir
wget $URL

One of the feature in my application involve changing of hardware setting. This require the user to be root or have administrative right.Before my application enable that feature, I want it to check whether the user is "root" or not, or whether user use "sudo" command to run the application or not, or whether the user has administrative rights or not.What are the codes or library that can do this?
