Programming :: Copy And Replacing Specific Line From File1 To File2 Line By Line
Mar 22, 2011I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.

Fedora Hardware :: Screen Too Bright (kernel 2.6.32.9-70 Onwards)
Apr 6, 2010I'm running Fedora 12 x86_64 Gnome and my video card is an ATI Radeon HD 3650. I'm using the open source video driver.After updating the kernel to version 2.6.32.9-70, my LCD display has started being too bright, which makes it barely readable.The problem is still there after upgrading to kernel 2.6.32.10-90. I've even tried to boot a live USB of Fedora 13 Alpha (desktop-x86_64-20100404.17.iso - downloaded from here - which ships with kernel 2.6.33.1-19)

Jun 5, 2010Fedora-13 will not play sound. It's definitely a kernel issue and I am not the only one from what I read elsewhere. Prior to kernel 2.6.28 audio works on this Samsung Q1 Tablet PC. Any kernels from 2.6.28 onwards will not recognize my sound card and therefore won't play sound no matter what. I've proved it running different livecds (Suse, Mandriva, PCLOS, etc.) with kernels 2.6.25, 2.6.27, etc., all with audio. How can I use/import a suitable kernel for Fedora-13 so that it will recognize my sound card (driver snd-hda-intel) on this Q1?

Ubuntu :: BBCi Streaming Jaunty Onwards
Feb 20, 2011I have an ongoing problem in trying to get Audio and video streaming to work with any version of Ubuntu.
Definition of problem: Playing any of the past library of BBC programs either Audio or Video will lock Firefox. Clicking o play a live stream from radio or TV would lock Firefox.
Only resolution was to force quit: Often re-booting Ubuntu would enable the player to work. SOmetimes this needed 4 or 5 re-boots before it would play. Then for no apparent reason it would stop and the cycle would repeat.
I have chased down dozens of threads and tried countless solutuions none of which has worked.
I upgraded to Karmic with similar results. I use the iPlayer a lot, not for downloading just for online streaming and this is causing me untold frustration.
My last upgrade was to Lucid and finally I thought it was cracked as everything seemed to run fine. I run a very trim system with very few installed programs, but within the past few weeks the iPlayer has stopped working pretty much altogether. It will play live stream audio, so fine for listening to the radio as I work, but trying to play any library programs whether audio or video and I'm back to a locked Firefox. I really am at a total loss on where to go with this and I find myself booting more and more into Windows 7 just to be able to function the way I want.

View 4 Replies View RelatedProgramming :: Print Images From Command Line At A Specific Size
Jan 7, 2010I have a requirement to print images (two to be precise) from the command line of a given size and without losing too much quality.
So, I may have two images, a.jpg and b.jpg which may be 4x4" and 6x4" respectively (the sizes may vary). I need to be able to print both these on a single sheet of paper (one under the other) at a given size for each - so a may be 2x2" and b may be 3x2" - the aspect ratio will always be maintained (or as near as possible!)
I am currently doing this a very messy way (because I don't know any other way!!) - basically I am converting the picture to a given size using a set density using convert and then concatenating the two using montage.
Here is part of my script:
Code:
Don't worry too much about the case statement at the end - that is just to be able to select to print either A, B or A and B.
The issue with this is that is doesn't work great if the aspect ratio is not maintained perfectly and also, it loses quite a lot of quality on the print.
I have a very old windows app which I wrote years back in VB (o dear! ) which does the same thing and the quality is fine (I am running it through wine). I want it to be command line though because I want to run it as part of other scripts etc.

General :: Removing A Line From File Which Is Having Specific Pattern Using Shell Script?
Mar 20, 2011I'm new to the shell scripting. can any one help in creating shell script for matching the content of the specific variable with file. it should remove that line from the file if line is containing same value as variable and keep the other content as it is.i used grep -v for accomplishing the same. But grep will remove the pattern which is similar.For eg. Assume file "test" contain datas :aaffif i used grep -v command for the pattern "a" to this file this will remove content "aa" from the file. I want the pattern only "a" should remove from the file, if it is existing. otherwise it should throw alert content not exists.

Ubuntu :: Allow A Specific User To Mount Or Remount A Specific Partition?
Jun 9, 2010my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)

Server :: Sendmail: Block Specific Sender To Specific Recipient?
Oct 1, 2009I'm trying to configure our mail server to block email from a specific sender reaching a specific recipient. In other words, if one of our employees is getting harassed by a 'stalker', how would one go about blocking, at the MTA (Sendmail) level, a specific sender email address from reaching a particular users inbox? We do not want to capture the email - simply block it before it consumes server resources.The Sendmail server (MTA) is a front end to our Exchange server so no user accounts exist on the Linux server. We simply use it as a SPAM and Virus scanner then forward clean email to the Exchange server.
