I've had a very colorful morning learning the innerparts of Linux's sort command, and have come across yet another issue that I can't seem to find an answer for in the documentation. I'm currently using -t, to indicate that my fields are split by the comma character, but I'm finding that in some of my files, the comma is used (between double-quotes) within values:
Jonathan Sampson,,foo@bar.com,0987654321 "Foobar CEO,","CEO,",ceo@foobar.com,,
How can I use a comma to terminate my fields, but ignore the occurences of it within values? Is this fairly simple, or do I need to re-export all of my data using a more-foreign field-terminator? (Unfortunately, I do not have any control over declaring a different terminator with this particular project).
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?
I want to merge columns (selectively) from several files and create a new file with the merge output. I saw some suggestions to use pr/paste to join the columns and then awk to pick-up the columns.
Code: pr -m -t -s file1 file2 | gawk '{print $4,$5,$6,$1}' But I have hundreds of files and I cannot manually pick up columns using awk as given in
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:
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.
I 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.
I'm trying to display fields from flat files where the first 8 fields are always the same. Fields 9 - n are varied but will contain specific patterns I'm after. I'm using this so far because "mySearch" is on each line I want to examine.
Code:
How would you pattern match and include 2 additional fields above field $9 but change field position from line to line?
Iam aware of the way on how almost every file can be converted to .pdf within Ubuntu 10.04 using "Print to File" function. But is there a way to merge multiple files to create one .pdf? OR Is there a way to merge multiple .pdf files to create a single .pdf?
So I found PDftk which seems promising Im also looking at the commands which are also very powerful..but I think its kinda of laborious to type all my 50+ pdf files in the command prompt I have the front end of pdftk I was wondering is there a program (I have Pdf sam and Pdf Shuffler) that will allow me to import unlim. number of files and then just jam it into one big PDF file?
I have a movie split into 3 iso image files, say, movie-1.iso,movie-2.iso, and movie-3.iso I did the following:
[ewn]# cd /mnt [mnt]# mkdir disk1 disk2 disk3 [mnt]# mount -t iso9660 -o ro,loop=/dev/loop0 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-1.iso /mnt/disk1 [mnt]# mount -t iso9660 -o ro,loop=/dev/loop1 /media/Hitachi_SATA_2TB/iso_files/Movies/movie-2.iso /mnt/disk2
[Code]....
the files for disk2, disk3 are exactly the same except disk2 has 2 .vob files instead of 3. Can I make this work by changing the names of some of these files before merging them into one directory and then running the mkisofs command to create a new single iso image? If so, what names do I give so that the movie plays correctly? If not, just how do you do this?
I have several image files accumulated as a result of taking screenshots. I want to merge all of them into a single pdf file. How can I do that? I save webpages in .mht format using UnMHT addon in firefox. Is there any way to merge several mht files into a single pdf?
Is there any bash script to merge pdf files in a directory and sub-directory and rename it as the directory/sub-directory name?Like for example using GhostScript/PDFTK/PyPDF etc?I'm kinda new where it comes to bash scripting.I found this script on a blog that seems to do what I want, however, the bookmark functionality is not of importance to me (and requires jPDFBookmark - which I can't manage to install)
this is not the right place to ask this question, but I found no other.I have an AAC audio file and a video file. Is there any way to merge them? I tried Avidemux but it won't let me open my AAC file.
one is : /home/pt/t/pa1.flv the other is : /home/pt/t/pa2.flv 1 o merge with ffmpeg ffmpeg -i /home/pt/t/pa1.flv -i /home/pt/t/pa2.flv -vcodec copy -acodec copy /home/pt/t/dd.flv the problem is: the merged file ( /home/pt/t/dd.flv ) just contain one file--the first one /home/pt/t/pa1.flv,there is no the second file--/home/pt/t/pa2.flv in the /home/pt/t/dd.flv
I am creating a game with random variables. In the game I have created a dialogue exchange to players. I have set up a table with various returns and I inserted {$fields} to represent various random variables. When I call on the requested fields, I only see the field text and my field names. Am I supposed to parse something and call it back another way?
ie: myfield is: "You have won {$random1} silver! <br />{$wi['gender'] majesty rewards you well." the code I am using to call that field is:
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.
The input file consists of several fields. The first field is always five or more characters long. I want to keep the last five characters of the first field.
Example: If the input file record is FEDERAL PACIFIC ELECTRIC PRODUCTS then I want to keep DERAL I can do this in four steps by using C, REV, C, and REV again but that seems like doing an easy thing the hard way. Is there a straightforward way to achieve this result with C or some other command?
I am using a cluster of machines running on Ubuntu 10.04 LTS which are supposed to be homogeneous, but apparently they are not. In particular, I am configuring the X server on these machines.The problem is that the BusID of the graphic card is PCI:5:0:0 for some machines, and PCI:3:0:0 for others. Is there a way that the X server automatically detects the appropriate Device (based on the name for instance)?
I have a file containing text. I want to replicate a specific field.For example, I might want to append a copy of the second word of each line to the end of that line.Have: Once upon a midnight dreary, while I pondered weak and weary,Over many a quaint and curious volume of forgotten lore, Want: Once upon a midnight dreary, while I pondered weak and weary, upon Over many a quaint and curious volume of forgotten lore, many Is there a Linux command which will do this? I seek a basic command, not awk, not Perl, because I haven't learned those things yet.
