General :: Run A File Check From Terminal In Ubuntu 10.10?
Dec 22, 2010
Occasionally Ubuntu runs a file check, and I assume repair if necessary, at start-up. what do I type into Terminal if I want to run a file check without waiting for the automatic file check to start? The reason I ask is that my system wouldn't boot last week and after several attempts to reboot, the automatic file check came into play and corrected whatever was wrong. This process of rebooting my system several times before Ubuntu fixed itself was very time consuming and frustrating. I dare say that there is a command line to trigger this file check.
i don't know if there is a way to check or see the list of commands available to each shell you decide to use, be it BASH,KSH, etc in your terminal. You know how its works in microsoft, in cmd-line or dos, you type HELP and its brings all the commands available for use.
I want to know that is there any command by which i can check which type of hardware devices are installed in my Linux box like SVGA,Sound Card,LAN Card.
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 have scenrio where i have to check first whether the files exists or not then count of records should not be equal to zero and file should be of current day not the previous day then only process my next task.There are three files totally.please let me know how to write script to achieve the same.
I've got a script to recursively create symlinks in my home directory to my settings directory, to keep the files under version control. I would like it to skip files which are already symlinked via a parent directory. That is, if I have these files/directories:
I am witing a file upload program in perl where i need to upload a wav or a gsm file and save it as a gsm file.How can i make sure that the uploaded file is a wav or a gsm sound file and not an executable malicious script or something.
I have a site that I login to to check updates. It does not have RSS because users need to authenticate themselves before getting access to the page. Is there a way to write a script that can login to the page and check whether the HTML has changed and then send me an email?
I have a small doubt regarding Assembly file compilation. I have two .s files. When I compile two .s files I am getting corresponding .o files. But when I compare the both .o files with diff command, it is resulting that two files are differing. How could/ what are commands we should use to understand the difference between two .o file's output.
create one tar.gz file that contains my /home, /etc, /root directory.
a) The process ended with a 88GB file size (which is ok) but with the following message.Code: tar: Exiting with failure status due to previous errors.I have searched a little but I could not find what went wrong.
b) What are the limitations of tar and gz for backups. Of course I fully understand that they can not be used for differential backups (if it is called like that)
c) Let's say that my backup will be a file of 100GB and I want to see the contents of the .tar.gz. In kde there is a program called ark. Can ark handle so big files? Does it use my hard disk (eg. /tmp) to uncompress the file so to show me its contents? It might be the case that might be the compressed file is much bigger than the left space on the hard disk?
d) How can I do an integrity check when my tar.gz file is created?
I have a text file with a long list of RPM's. I need to check if each RPM is installed. I'm sure I can cat out this file and run "rpm -qa" against it, but I'm having trouble with the syntax right now...
I have been using linux for a bit of time but would still class myself as a noobie. I dont know excatly what I am looking for but I can best describe it in a sanario. I have started creating bash scripts which are looped indefinetly which checks afor files to process. my problem is, is there any way to check if the file is complete, as if the file is large and is being coppied from a different volume the file may still be copying or if the file is being uploaded by a user over samba/nfs, and if the file is still copying the process will most likely fail.
i have problem during boot my F11 , the problem is :
Code:
checking file systems /dev/sda7 : superblock last time ( etc... ) /dev/sda7: Unexpected inconsistency ;run fsck manually (i.e,without -a or -p option) ***an error occured during the file system check ***dropping you to shell:
So I want to run command through ssh but also run a if check in bash to see ifa file exist. I know that to run ssh commands you do ssh user@server YOURCOMMANDbut if i need to run an if statements, how would this work??
How can I check what window manager (compiz/metacity) I am using in the terminal? I know how to change from one to the other or to just visually see what is currently running, but I need to know a way to check in the terminal for a script. How can I do this?
Is there a way to check your up/down speed using the terminal? My internet connection seems to be limited at about 1MB/s, judging from how one program works, after reinstalling OS.
i want to upload my iso collection to adrive(.)comi have a slow upload and i want to split each iso file in chunks of 100 MB so they upload while every browsing session of mine.i figured i should use split and cat commands to do that.but i cant afford to upload some corrupt archives, so how may i go about checking the small chunks to the original file before uploading
I have a few questions to ask, so please pardon me
1) How to check for https in commands config file for Nagios? I only know how to check for http, not sure for https.
2) The log file in Nagios, is it possible to extend Nagios's plugins (or are there already have plugins existed) so that we could actually make use of the log file to check for status of each and every services in different hosts, instead of looking through the log file manually which can be very time-consuming if the list is very long.
So, what I am asking is, is there a way to ignore/over-ride compiz's texture size check, a different way to query xrandr, or is there a completely different method I can go about checking if an external monitor is connected?
When I try to ping with the terminal to check a website's availability, it always just keeps going on and on and on... How do I get it to stop after a set amount of pings? Is there some type of command?
i have been using ubuntu for just over 3 months now and i completely love it. but heres where the problem starts (and please let me know if i am in the right topic) i recently installed ubuntu 10.10 on my roommates computer, the reason being is that the IT department here on college "fixed it" for him, now it wont connect to the internet. it will however connect if we use an ethernet cable from the other laptop to his. his had originally windows xp then got upgraded to vista. i was wondering if there was a way to completely reset the networking wifi card if that might be the problem.
my roommates computer is a DakTech PlaidBook, however i do not know on how to check the system information in the terminal to tell you what wifi card he has and such, all i want is to have internet back on his computer again.
After moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however.
The setup is a bit complex, as follows:
I have Ubuntu 10.4 as development machine, trying to mimic the server as much as possible We use Eclipse + SVN and I create all projects in a local folder under my user account In /var/www-vhosts I create folders for each vhost, like this one: test.localhost test.local/index.php: includes the index file of the project test.local/.htaccess is a dynamic link to the htaccess file in a project subfolder
I get the following error in the apache error log:
The problem seems to be the .htaccess file, or the link to it. When I empty the htaccess, nothing changes When I remove the link, the index-include produces some output (in the apache error log) When I remove the link and replace it with the actual file, I get another error:
I have two linux servers, they are backup together.
1. Server 1 have 3 files with name: file1, file2, file3 in the path: /etc/sysconfig/network-script/.
2. Server 2 have 3 files with name and path are the same as server 1.
- How to make a script to copy 3 files at server1 to overwrite on server2. But before overwrite, this script will check and compare the last modified date of these 3 files(on server1 and server2). if the modified date of file1, file2 or file3 on server1 is newer than 3 files on server2 then overwrite process will do, if not, will do nothing.
- see my script as below: it works find now but just overwrite. not check last modified date.
Tried upgrading from 8.04 lts to 10.04 and it wouldn't work b/c of too many mods to my 8.04 system? So I tried a fresh install per usb stick. System kept locking up during install, as well as when I run it from the usb, I've since learned. graphics card? I can't log into windows either per the grub loading please wait error 15. I've googled & searched the forums & everything I've tried doesn't work, there were some possible solutions that I don't understand how to do. can't get to a terminal to check or modify anything. Hitting "e" at the boot menu does nothing. I don't know how to do anything from here! Compaq Presario SR5350, 2GB RAM, Dual Core Proc 2150MHz. Dual boot w/Vista, HDD is partitioned separately with Root, Home & swap. Also, sda5 or / has been formatted to ext4, still using grub 1.5.
