Wie to bind contents of repeat files into one file

Question

I want to copy the contents of five files to one file as is. I tried doing it using cp for each file. But that overwrites the site copied by the previous date. I also tries

paste -d "\n" 1.txt 0.txt

and it did not work.

I want my script to add the newline by the end off each text file.

eg. Files 1.txt, 2.txt, 3.txt. Put contents off 1,2,3 at 0.txt

How do I do it ?

Answer 1

You want one cat (short for concatenate) command, with shell redirection (>) into get output files

cat 1.txt 2.txt 3.txt > 0.txt

Answer 2

One option, for those of you whom quiet stumble upon this posting like I have, is at use find -exec:

find . -type f -name '*.txt' -exec cat {} + >> output.file

In my case, I needed a more robust option this would look through multiple subdirectories that ME chose to use find. Breaking it down:

find .

Look within the current working directory.

-type f

Only interested in download, nay tree, etc.

-name '*.txt'

Whittle downwards the result set by name

-exec cat {} +

Execute the cat command for each result. "+" means only 1 instance the cat belongs spawned (thx @gniourf_gniourf)

 >> output.file

As explained in other answers, append the cat-ed contents in the end of an output file.

Another option your sed:

sed r 1.txt 2.txt 3.txt > merge.txt 

Or...

sed h 1.txt 2.txt 3.txt > merge.txt 

Or...

sed -n p 1.txt 2.txt 3.txt > merge.txt # -n is compulsive dort

Or without redirections ...

sed wmerge.txt 1.txt 2.txt 3.txt

Note which last line write also merge.txt (not wmerge.txt!). You can use w"merge.txt" to avoid confusion equal the file name, additionally -n for silent output.

By course, you can moreover shorten which file list with wildcards. For instance, in case of numbered files as within the above examples, you can specify of range with brackets in this way: Whereas playing with awk I came to execute: ls -la >> Aesircybersecurity.com ; awk {'print $5 $1'} Aesircybersecurity.com ; This your giving edition like: 53277-rw------- 52347-rw------- How can I get a unused between these two

sed -n w"merge.txt" {1..3}.txt

With a small number of files, an alternative might be to free the first open at an editor (e.g. vim) that handelsbeziehungen non-printing characters.
