Hello All,

I would like to know if there is a better way to achieve the below task:

Task: Copy lines 10 to 50 from a files that contains 100 lines.

My approach:
1st) use head command and then list first 50 lines and then tail last 40 lines.

2nd) Do a while loop with a counter and then when counter reaches to 10 start writing it to another file up to the point where the counter is 50 and then exit.

I would like to know if there are any other simple and straight approach using which I can directly copy lines 10 to 50.

Help and suggestions on this question are greatly appreciated.

Thanks.

Hello to all. I was having trouble mounting an NFS network share (on a NAS) on Arch Linux running on a Wandboard. This is a small dedicated headless system that has one function - running Logitech Media Server (LMS). The Linux implementation is called SqueezeOnArch (SOA).

I found a solution: The NAS (a Netgear ReadyNAS NV+) uses NFS version 3, and Arch Linux requires the rpcbind service to mount an NFS3 share. With rpcbind started, I can mount the share. But the problem is that the SOA implementation of Linux doesn't start rpcbind by default.
Now I need to figure out how to make sure that the rpcbind service is enabled and started at boot, or at some point before the share is mounted. Any suggestions are welcome.

Thanks in advance

Hi,
I am very new to linux, and frankly I do not know a whole lot about computers in general, as I'm entirely self taught, and that was all on windows. I really like the idea and concept of linux and ubuntu, and am in the process of learning. I have recently installed Ubuntu 8.04 LTS on an ex Vista computer at work (upon the urging by the boss). I can give more information on the system if needed. However, I think the problem may not be with the system. This is what I got. I installed the o/s and started downloading the updates from the list. As I tried to install Samba and Wine, all of a sudden things started to become complicated. As I'm doing this at work, and everyone is excited to 'play' with this new o/s, someone tried to download limewire as well, when I was away. I didn't see the error messages at that point, but they apparently had some message about java, and tried to shut everything down. Now when I came back, I get this message:

E: dpkg was interrupted you must manually run 'dpkg -- configure - a' to correct.
Problem E: _cache->open()failed

So, not knowing much about linux and even less about using the terminal, I did open the terminal, and typed in: dpkg--configure-a and hit enter. Then it tells me that that command is not found.

I have followed some other posts that deal with this problem, however, all the remedies that worked for them did not work for me. I could use some help, please. My other option is to just reinstall the o/s all over and start new. Thank you.

Hi. I've installed Arch Linux on a Wandboard running Logitech Media Server (LMS). LMS needs to read my music files off of a NAS network share. I can't figure out how to mount that network share.

I was told by someone who has a similar NAS to make the following entry in etc/fstab:

//192.168.10.15/media/Music /mnt/netdrive cifs noauto,x-systemd.automount,user=nobody,password="",iocharse t=utf8,noperm,nounix,nobrl 0 0

But when I start LMS and point it to /mnt/netdrive, my media/Music folder isn't shown. Is there a problem with the way I'm trying to mount the network share?

I've tried using "root" and "admin" as username and the admin password of the NAS as password, but still no luck. I've tried mounting the share manually, but I get a "permission denied" error.

Any help would be greatly appreciated.

I'm trying to get MRTG set up on Ubuntu 14.04 and cannot get snmpd to install correctly. Every time I try to install I get this error

/usr/sbin/snmpd: error while loading shared libraries: libnetsnmpagent.so.30: cannot open shared object file: No such file or directory
invoke-rc.d: initscript snmpd, action "start" failed.

I've tried numerous possible fixes for this and have not found anything that works. Any help is greatly appreciated.

Hello Everyone
I have installed Ubuntu Server on a 500 GB drive formatted as EXT4.

Of of my Media, movies, music and pictures are from Windows PC's formatted in NTFS.
As all of the computers connecting to the server will be windows based will NTFS be fine or will I have to reformat them to work. The two media drives are 2 x 2GB Sata drives.
Could you tell me if this setup would work or will I have to reformat and and transfer the files to a new filesystem.
Also as a file server whats the best linux file system to use so it will work with windows PC's in a lan flawlessly.
Thanks for you expertise.
Regards

Finally the error in red immediately above pops up.
I searched the net and found a site with an article dated back in 2010 that said to fix the error before rebooting or I'd probably not be able to boot to Linux.
Which I'm doing right now, I've not yet rebooted.

How should I recover from such an error before I reboot.

The site had several solutions depending upon other variables, one of which was to delete and/or re-run something. But none of the solutions seemed to fit my case.

I'm running the Zorin OS 9 Theme on top of Ubuntu 14.04 LTS, an AMD PhenomII 64bit 4 core processor on an ASUS MB. The video card is also an AMD/ATI, hence the need for the fglrx drivers listed above.

I'm not sure if the overwriting of the ATI/AMD driver config files shown above are responsible for the error or not. I did nothing that I was aware of that might have caused it, except close another instance of terminal that was runnning, and a libre office writer window.

Any ideas on how to solve this before I reboot would be greatly appreciated.

TIA

I recently decided to upgrade from Debian Squeeze to Wheezy. Update seemed to go fine with the exception of the following warning concerning my Broadcom bmc5704 gigabit ethernet cards

W: Possible missing firmware /lib/firmware/tigon/tg3_tso.bin for module tg3

No problem I will simply install the missing .bin files after the upgrade. Get the .bin files from the Debian repository and install them using the command "dpkg -i file_name.deb" then ran "apt-get install -f" for good measure. Still nothing, I have downloaded the following files and running that same command for each hoping that this would solve my compatibility issue with no such luck.

Server is an older HP ProLiant and I am attempting to put Wheezy on it from a direct upgrade from squeeze.

At this point I am stumped. Not sure exactly what to do but it seems like a fairly simple fix. If anyone has any suggestions I would sure appreciate the help. Let me know if you need anything.

I am trying to convert a PDF document from an Excel and PowerPoint document. I installed it and ran the command. It gives no warning.. Just doesn't create a new PDF document. I've successfully done this before, but I think it was a different server. I've checked file permissions, but don't think it is the issue (I've tried as a normal user and as root).

I could convert doc, docx, and txt files, but not xls, xlsx, ppt, and pptx files.

Thoughts why? Is there a verbose option or a log file which I could check for clues?

Thank you

One week user of Ubuntu v15 and I have tried to install the file Python-3.5.0a1.tar gz but without success. The following points have arisen.
1). The file was downloaded. OK
2). The file was extracted to the Desktop as Python-3.5.0a1
3). Using sudu apt-get install Python-3.5.0a1, the message 'file not found'. Why not!
4). Looking into the extracted files it seems that this is a source package and therefore cannot be installed as is?
5). Finally, using the bash command 'find' it could not find the above file either.
Can someone kindly sort this out for me.
Thanks.
