how I can merge the data from file1(data per line) to the end of line of file2. So what I mean is, I want to add every line from file1 to the end of the corresponding line of file2.
View 2 RepliesI 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.

The goal is to auto-update a webpage that contains links to network devices. These devices are all set to DHCP, and their hostnames are not guaranteed to stay the same, so static IPs or accessing via hostname is NOT an option.
Process: Run a script every hour or so to query devices on the local network to generate a list of responding devices by MAC address and what their current IP is (results.lst). Using a "static" MAC address list file "printers.db" as the database search "results.lst" to find specific MAC addresses. When a match is found, grab the IP from "results.lst" and update "index.html" with the new IP address. No comparison needs to be done between "results.lst" IP and "index.html" IP as I just want to overwrite whatever is there.
Here is what I have so far (using dummy data): PRINTERS.DBProduct Mac Address Printer1 00:00:00:00:00:11 Printer2 00:00:00:00:11:11 Printer3 00:00:00:11:11:11 Printer4 00:00:11:11:11:11 Printer5 00:11:11:11:11:11 Printer6 11:11:11:11:11:11 TEST.SH

I'm working on some code where I have two files. I know I can use cat file1 >> file2 to append file1 to the end of file2. What I was wondering is how I could append the first line of file 1 to the end of the first line of file2, then the second line, and so forth.
So if file1 was :
cat
dog
mouse
file2:
orange
red
blue
I want file2 to be:
orange cat
red dog
blue mouse
Also I need it to remove any duplicates from the same horizontal line.
I'm learning Bash and can't find how to say "if file1 exists and file2 exits then...".I thought this may work:
Code:
file1="/root/file1"
file2="/root/file2"

I wish to add information to one of my files based on matching IDs,
Here is an example
(the id is the 3 colunm)
(the ID is the 2 colunm)
And the output i wish to be
OUTPUT:
So as you can see the ones that do not match are still present, and the ones that do match just have the extra information from file2.txt added to them.
I thought about using join but that only seems to join the ones that match displays thoes only. i would like all the information in the output file.
I'm a bit new to Python programming and hoped that someone might be able to help with a problem I'm having. What I essentially want to do is to combine two text files line for line. I know how to do this in a bash script so to give you a better idea here's the code for that:
Code:
This is basically for adding on values to the end of a CSV file that uses ';' as the delimiter. So say file1 said:
And file2 said:
Then running this command would create merged_file1_and_file2 which would be:
The code I'm using at the moment is:
Code:
As I'm sure any experienced python programmer will see, this prints out the first line of the file "csvraw" and then all of the lines of "stamps" and then the remainder of "csvraw".
What I'd like to do is something like: (pseudo code, I know it's not python ;-))
Code:
Is this possible? I've tried googling and my Python Pocket Reference hasn't been much help. I've looked at pickling but that doesn't seem appropriate.
I have a script generating some containing multiple lines. But I want to merge all lines using comma separated.
View 6 Replies View RelatedI am using ffmpeg for merge wav files to a mov video. My doing is below
1. First extract audio (wav file) from video
2. Create wav file from mp3 track 1
3. Create wav file from mp3 track 2
4 Merge extract audio from video with track 1 and track2.
Now finally create a new video with original video's video stream and merged audio stream.
Process is working. However final video is 3-4 times greater than original one. I want that final video should be near about size of original video. As I understand, all three wav files (created from ) make video larger.
Example commands i using is as below:
i got the slackware folder with my builds of my favorites packages, in /tmp i create the new versions of that packages. theres is a way in bash to replace the new ones in /tmp with the old ones in /home/user/slackware??

Two files contain:
file1:

How do you change the case of the letters in file1.txt to uppercase and compare with file2 all in one command?
Searching Google on how to join/merge many mp3 files, it suggests that I should just cat them together.That might "work", but clearly it is not the correct way to do it, as each header and set of IDv3 tags will also be concatenated.Does a Linux program exist that can be scripted to join/merge many mp3?Can mplayer/mencoder/ffmpeg do it?

View 2 Replies View RelatedI have a linux hard drive with three areas:
/dev/hda1 - ext3 boot partition (20 MB)

unpartitioned space - 12 GB
I would like to merge the unpartitioned space into the lvm2 partition known as /dev/hda2. I tried using GParted, but it does not support lvm2. What commands or utilities could I use to add the unpartitioned space to hda2 without losing my existing data?

What I want to know is if I can, without losing data, add the disks to RAID and then merge the partitions? All the partitions are of the same type. Or would it easier/better/possible to do this with LVM? Even if I'd have to shrink partitions and copy data to a new LVM one to get it set up properly, would it be better than RAID 0?

1. Is there an easy way to combine pdf files not only one "after" the other, but also one "next to" the other? For example, If I have one-page files called a1.pdf, a2.pdf, a3.pdf, a4.pdf, b1.pdf, b2.pdf, b3.pdf, b4.pdf, c1.pdf, c2.pdf, c3.pdf, c4.pdf, I want to combined them so that I can scroll down from a to c and scroll right from 1 to 4. That is, I want to merge them in "matrix form". If I zoom out the final file should look like:
a1 a2 a3 a4
b1 b2 b3 b4
c1 c2 c3 c4
(TWELVE pages in total)
Is this possible? I tried Google but found no information.
2. Also, is it possible to just put all of them together in a single page. If I zoom out the page should look like:
a1a2a3a4
b1b2b3b4
c1c2c3c4
(ONE page in total)
Note: I would like to do this for many one-page files

Any idea which tool should I use on a Linux system?
I have a folder with hundreds of .txt files (logs of some java application) that I have to merge in to one single .txt file. This application produces a new log file everyday:
day1: logFriday10September2010.txt
day2: logSaturday11September2010.txt
...
day8: logFriday17September2010.txt
...
and so on...
I could merge the files easily with "cat" and ">>" however, the problem is that I have to do it by taking into account the date (creation or modification) of the file.
If I simple use the cat command the output file will receive for example, all Fridays in a row, then all Saturdays, etc. and in that way I'm not considering the date.
I've searched for the options of the find command, since the files after creation are not modified...I try to use this for example:
$ find . -newer <some old file>
but that lists me all files after that <old file> and not by correct date.
My question is probably better explained by example; I have two files that look like this:
Code:
$ cat file1.txt
mercury
venus
earth
mars
[Code]....
The general stipulations are as you'd expect; both files are of an arbitrary length, generally file1 will be larger than file2 but this is not guaranteed, the common lines (if any) will always be contiguous and only occur at the end of file1 and the start of file2.
I recently finished installing Fedora 9 on a Prolient ML 330 G6 Server, but i configured the SATA hard drives to be viewed as four seperate hard drives. I was asked to merge the drives to be seen as one 800GB hard drive, my biggest fear is that we had set up Samba to share folders between fedora 9 giving specific users access to specific files saved on the Prolient server, will those settings be lost.And could you call that a File Server or do you have to enter any more settings And also if anyone could point me to a tutorial on Logical Volume Management and Raid specifically for fedora 9
