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

I have 2 very long files which are quite similar:
file1.csv:

file2.csv:

I need this output:

explanation:
If the fields 3 (serie) and 4 (modello) are identical, the lines of the 2 files should be "added":
Code:
If the fields 3 (serie) and 4 (modello) are different, just print the line of both files:
Code:
Is there a way to do this without reading the (huge) files with a "while read line" loop?
I'd like to extract a single column from 5 different files and put them gether in an output file. I saw a similar question for 2 input files, and the line of code workd very well, the code is:awk 'NR==FNR{a[NR]=$2; next} {print a[FNR], $2}' file1 file2I added the file3, file4 and file5 at the end, but it doesn't work. Does anyone know what do I have to do?

I am having a souce file (say SOURCEFILE) as below with 5 columns and many rows.
pol name status loan address
123 aaa 21 100 RJY
234 bbb 31 200 RMY
345 ccc 21 300 SJY
456 ddd 41 400 pqr
i want to compare the file (say COMPAREFILE ) which is below :
123
345
I need the following output file (sayOUTPUTFILE) as below :
( ie for file COMPAREFILE i need column 2, column 4 ie name and loan from source file )
ie output file required is to be like below :
123 aaa 100
345 ccc 400
Till now iam using the following method.
1. cutting column 2nd column
2. again cutting 4th column
3. in third, step merging the 2nd and 4 th column.
method of writting single line command or any awk programme to do this in one step.
I need output file (say OUTPUTFILE) as below
I've searched everywhere and I can't come up with a good solution. For each line I need to find the average, min, and max. I've seen plenty of solutions where the number of columns is fixed, unfortunately for me these lines can get pretty large. My thought was to read each line individually into an array, loop through the array and find the avg, min, and max that way but i haven't had much luck. I can read each line using a while loop but I'm having trouble with the array part, or perhaps that's not the best solution?

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?

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
I was trying to do a school assignment in LaTeX. The assignment involves having the page split into three columns: the first column is for the quote, the second is for a reaction, and the third is for questions. These columns must be able to break in the middle of a row. I was trying to accomplish this using LaTeX.
First, I tried the longtable environment, but that would not allow me to pagebreak in the middle of a row. Then, I tried parcolumns, but for some reason, the second "row" had a huge space between the first two words. Does anyone know of an environment suitable for this kind of work?
I have a folder with only 24 files named <number>.dat (i.e. 4.dat, 6.dat and so on) where <number> is between 0 and 256. Each file has just two columns of data and nothing else.
I'm trying to combine all the second columns ($2) together. I've been fiddling around with getline and so far have
awk '{ getline ln < "6.dat" ; print ln" "$2 }' 4.dat
which takes file 4.dat and adds $2 from 6.dat, but I want a single command to take each $2 from every file and add them to (for example) 4.dat (having $1 from 4.dat is no problem). A command that takes every file in the folder and grabs $2 and places them in a common file would be ideal. Frankly I can work around if you combine both columns from every file.
How can I join the two parts of a stereoscopic movie to get a side-by-side one?
I can expand the left file, that way all I'll need is to paste the second one on top of it, with something like this:
mencoder left-file.mkv -o side-by-side.avi -oac copy -ovc lavc -of avi -vf scale=1280:720,expand=-1280:0:0:0 -sws 3 -lavcopts vbitrate=16000
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.
Each line of the file I am sorting is in the following format:
<url> <month> <day>
For example:
[URL]
I wrote the following to sort:
Code:
#!/usr/bin/perl
$in = shift;
chomp($in);

The script worked fine for my small testing files, but failed in my input file. The input file is 18MB and containing more than 300,000 lines. The output will contains some lines like that:
url_one 10 1
url_two 10 1
url_three 10 3
url_four 10 1
Is that because my file is too big for perl to handle ?

I've been looking though different editors for one that has good printing support. Ideally it should be able to print C++ code with line numbers, syntax highlighting, multiple columns per page, customizable fonts and sizes and a print preview feature so that I can make sure it looks right before sending it to the printer. It appears that notepad++ had at least some of these features, but it is not available on linux. The best I could do so far is to copy/paste the output of 'cat -n foo.cpp' into oowriter and format it into two colums. I don't get synax highlighting though and I have to manually replace tabs with a few spaces as well as some excessive leading spaces before the line numbering.
