Software :: Join 2 Text Files Based On First Number Present In Every Line Of The 2 Text Files?

Jan 22, 2010

I have 2 text files : file1.txt and file2.txt

cat file1.txt

15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces

cat file2.txt

2 this is sentence1file2
6 this is sentence2file2
54 this is sentence3file2

I would like to join these 2 files. The result should look as follows :

cat joinedfile.txt

2 this is sentence1file2
6 this is sentence2file2
15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces
54 this is sentence3file2

==> so the joined file must be sorted on the first number. Any ideas how this can be achieved ?

Programming :: Using Python To Merge Two Text Files Line For Line

Jul 6, 2010

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.

Ubuntu :: Command Line To Copy Files From One Location To Another / Retain Source Files Group / User?

Feb 20, 2011

Is there a method at the command line to copy files from one location to another and retain the source files group and user?I'm migrating some MySQL files from one machine to another.I want to back-up the original files in the directory presently. They have owner:group of mysql, some have owner:group root:mysql and so on. To copy them under cli or Nautilus everything changes to root for I execute sudo cp or gksudo nautilus and copy via gui.

Since it is MySQL data I could simply do a dump of the database and restore it on the other machine. But there's about 20 db's and I want to do this via a copy for it will be faster - at least that is what I think.

Ubuntu :: Command Line - Find And Replace Text Within Multiple Files?

Aug 28, 2010

I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.

Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier.
If I was searching for a single word, I can see ways to do this.
If I paste the code I'm searching for into a text file, is there a way to:
find (contents of oldstring.txt) and replace with (contents of newstring.txt)?

Programming :: Copy And Replacing Specific Line From File1 To File2 Line By Line

Mar 22, 2011

I 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.

Programming :: Copy An Entire Line And Add That Copy At The End Of The Same Line?

how do you copy an entire line and add that copy at the end of the same line?

For example, sometimes I rename a collection of files with a command like:

"mv oldfilename newfilename;"

I am able to add "mv" at the beginning, the semicolon at the end and sometimes replace a word in the middle, but... how to change a line "oldfilename" into "oldfilename oldfilename"... that is already long time a mystery to me...
