As you can see, the first command gives numbers like C841-0655. But for the optical disks (iso9660) it gives them not. Neither does the second one. This number is known as 'Volume serial number' in MS-DOS, and is printed on console with the command 'dir' not only for the HDD partitions but for the optical disks too. how to get an optical disk Volume serial number? Notice that this number is inherent to the media (is a property of the media, under any O.S.).
anyway i need to take the average of all rows with the same 1st number(key). i.e.
1, 3, 4.66, 5.66, 5 2, 3.5, 4.5, 5, 3.5
I know this is something awk/sed would be great for, i just dont have enough experience with them to accomplish it, Also, what about averaging those columns together? so, after I output this to a file, id like to get another like:
1, 4.58 1, 4.125
The number of colums to add might not always be 4 either. EDIT: this might be easier to do in gnuplot, so I mainly just need an answer to the first part.
Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.
I am new to linux. I am trying to install suse 11.3 on my desktop which has following configuration:
Intel Pentium 4 processor 32 bit 512 mb RAM 80 gb Hard Disk
I made a 20gb partition on my hard disk and formatted it as fat32 for installing suselinux on it. I changed my boot priority and booted the system from the bootable dvd. The problems are:
1). Message is displayed telling to ensure that cd 1 is in the drive. I cannot make out what this means when the dvd is already in the drive. If I press ok same message keeps coming if I press back following occurs. 2). The installation starts and asks for language and keyboard type. Then it asks me to specify the hard disk and then a message is displayed that it cannot find repository.
How do I find files in opensuse 11.2 without using the command line. I see in dolphin "nepomuksearch", but it doesn't work. Even in the command line you cannot whereis a file like Monday, Monday.mp3. whereis also seems to be case sensitive.
i have installed ubuntu version 9 and i cant seem to find where hard disk partitions are,what do i do?also what do i do to install the webcam and to change from gnome to Kde enviroment!!i also installed virtualbox but i seem not to find the icon
On a small network i have 3 WinXP computers and i've just installed a two new ones with Win7 pre-installed. As server i'm running OpenSuSE 10.3 and Samba with only one share. As i mount it to WinXP computers all get same volume serial number:
V:>dir Volume in drive V is AppDrive Volume Serial Number is 8CD5-975C
...and all Win7 computers get a diffrent one:
V:>dir Volume in drive V is AppDrive Volume Serial Number is A0D3-975C
We use application witch somehow only works when one/same volume serial number on a mounted drive is used.
I need to find each line in a file which does NOT begin with a double quote (") and append that line to the previous line. I have been successful doing this using the following command: cat filname.csv | sed -e :a -e '$!Ns/ [^"]//;ta -e 'P;D' > newfilename.csv
My issue is the substitution. As you would expect after the line is appended to the previous line the first character is removed. I need it to not be removed. I tried: cat filname.csv | sed -e :a -e '$!Ns/ [^"]/&/;ta -e 'P;D' > newfilename.csv but it just hangs.
Goal: Input: "line 1" line 2 Output with existing sed command is: line 1ine2 I need it to be line1line2.
I'd like to measure network latency for SNMP GET request. There is a free command line tool time which can be used to find timing statistics for various commands. For example it can be used with snmpget in the following way:$ time snmpget -v 2c -c public 192.168.1.3 .126.96.36.199.188.8.131.52.1.10.2IF-MIB::ifInOctets.2 = Counter32: 112857973real 0m0.162suser 0m0.069ssys 0m0.005sAccording to the manual, statistics conists of:

I had a dual boot (windows 7 + debian), both of them installed in my internal hard disk, with the GRUB in it. I have recently installed a second linux distro (mint), but I put it in an external hard disk. Now the GRUB allows me to boot any of the three operating systems, but I need the external disk to do it. It seems that after the mint installation the GRUB is now working from the external disk (if the external disk is not connected, the machine does not boot.) �Is there a way to change the location of the GRUB, to the internal hard disk of my laptop?
after my upgrades i noticed one hard drive was acting funny i was gonna reformat the drive anyway to totally remove winblows from my system grub was installed on the boot sector of the drive that failed how can i get the next drive in line to boot if some one can get me to a howto or tell me what i need to do short there of reinstalling the operating system.
How do I check my hard disk Revolutions Per Minute (RPM) speed from a Linux shell prompt without opening my server case? any other third party utility please let me know.Ieferenced some other articles. they give only model number, serial number and disk space.
Ubuntu is getting stuck at the loading screen after an aborted attempt to upgrade to 11.04. It's my own fault - the install was running out of room on /, and I, like an idiot, decided to delete some package files under /var/something/archive, thinking they were "old"... I quickly realized they were in fact the new packages being installed... anyway after killing the thing and rebooting it is pretty damn broken (mostly because I can't get networking going so running in dpkg repair mode doesn't do much because, well, I deleted the packages).
I want to copy all the files off my /home and other meaningful partitions onto an external drive so I can just do a clean install. I can actually login to the command line under recovery mode, but I can't get the GUI started. I know it's possible to copy the contents of the partitions to an external
