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 :: Is It Safe To Comment Out Old Entries In GRUB?
Aug 8, 2011I recently installed F15 on my laptop. Earlier today I updated a little bit more than 500 different things, and then rebooted. Upon seeing the GRUB menu, I saw that one of the updates added a newer menu entry for Fedora- the newer one's version was a fraction higher than the older menu entry.Anyways, is it safe for me to comment out the old entry in /boot/grub/menu.lst?

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.

General :: Comment On Partitioning Strategy?
Mar 7, 2011I'm planning to partition a new hard drive to dual-boot Mint+Mepis. I've read partitioning tutorials and posts, and want to check my understanding--I'd appreciate input from an experienced person.For 500GB hard drive, dual-boot Mint+Mepis:
--Mint: / root partition for OS; /home partition for ease of upgrading
--Mepis: same as Mint
= four partitions
And:
/swap partition to be shared between Mint+Mepis
/shared partition for shared data
= two partitions
Total = six partitions
Since four primary partitions are allowed, I should use three primary partitions and one extended partition containing three logical partitions.Is that correct?If so, what should go where? I assume there's an optimal strategy--Should each /root of Mint+Mepis go in a primary? What should go in the other primary, and in the three logicals? Or maybe I don't need three primaries?--use two primaries and four logicals?

Sep 15, 2010Have spend I while searching the net for at PDF annotator for Linux, but can't seem to find any. Most of the forum and blog post I found on the subject suggested different programs, Common for these though, is that they don't do annotations in the pdf, but rather import the pdf as a background for writing on top and then saving your notes separately. This have to problems:
1. You can't comment a pdf and mail it to your co worker.
2. You can't switch between programs freely...
As far as I know the pdf format has capabilities for annotations/comments. So anybody know how to take advantage of this, for note taking? My use for this would mostly be notes on slides during lectures etc.
General :: Find Pattern And Comment Out 2 Lines After It?
Oct 14, 2010How do yo find a pattern with sed or awk and then:
- add a # at the beginning of the line containing it
- and add a # at the beginning of the following 2 lines, too?
Say, I want to comment out the line containing "which 0launch" and the two lines following it:
if [ -x "`which 0launch`" ]; then
exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
fi
Expected result:
#if [ -x "`which 0launch`" ]; then
# exec 0launch http://rox.sourceforge.net/2005/interfaces/ROX-Filer -S
#fi
I need this because I do not want to comment out every line containing "fi", just the "fi" of this specific if statement.
