[SOLVED] How to insert Text from one file to multiple files

timmo · 2022-01-04 11:45:53

Hey best community on the internet,

I think the solution is pretty simple and probably I can't find the right search terms.

I used obsidian.md for an RPG Campaign I'm planning and made a lot of pages. Then I decided that a dokuwiki suits my needs better. So I bulk renamed the .md files to .txt. I used sed to remove all unnecessary markup and prepare internal links for the dokuwiki namespaces.

Now I have 274 content.txt files, each with a unique name that I want to keep.
And I have one template.txt with template code for the wiki pages . There is a specific line in the template where I want the content to be.

I thought there must be an elegant solution for this.
I thought about something like:

1. Splitting the template.txt at the point where I want the content to be. I'd get template_part1.txt and template_part2.txt
2. Then prepending template_part1.txt at the beginning of each content.txt
3. Then appending template_part2.text at the end of each content.txt

4. Win! Finally I can upload all files to my dokuwiki without having to copy&paste for several days.

Please help me finding a solution or the proper search terms.
Thanks in Advance

Solution

Always make a backup of your files!

1. I splitted template.txt in part1.txt and part2.txt . They are located in the parent directory

2. I opened a terminal in the folder with all the content.txt files.

I used:

sed -i '1r ../part1.txt' *.txt

to insert part1.txt at the beginning of each file and

sed -i '$r ../part2.txt' *.txt

to insert part2.txt at the end of each file.

3. Win

To append to multiple files:

tee -a copy1 < src | tee -a copy2 | tee -a copy3 | ...

Sorry that's not quite what I'm looking for as it only appends the text and I have 274 Files. But thank you.

Here are examples of the template, content and what I want.

my template.txt:

...code code code...
<WRAP noprint>
<button type="danger" collapse="gmn">GM Notiz: !Nicht lesen! </button>
<collapse id="gmn" collapsed="true"><well>

======> Insert content.txt here!

</well></collapse>
</WRAP>

example content.txt:

  
...content content content...
**Primary Populated Planet**  
Atmosphere: Breathable mix  
Temperature: Warm, wet  
Biosphere: Human-miscible biosphere  
Population: Severals million inhabitants  
Tech Level: TL 4 Baseline postech  
World Tag #1: [[worldtag:Area 51]]  
World Tag #2: [[worldtag:Tyranny]]  
...content content content...

The content.txt I want:

...code code code...
<WRAP noprint>
<button type="danger" collapse="gmn">GM Notiz: !Nicht lesen! </button>
<collapse id="gmn" collapsed="true"><well>

...content content content...
**Primary Populated Planet**  
Atmosphere: Breathable mix  
Temperature: Warm, wet  
Biosphere: Human-miscible biosphere  
Population: Severals million inhabitants  
Tech Level: TL 4 Baseline postech  
World Tag #1: [[worldtag:Area 51]]  
World Tag #2: [[worldtag:Tyranny]]  
...content content content...

</well></collapse>
</WRAP>

In that case you might want to edit the thread title to say 'insert' instead of 'append'.

So I think I may be on to something.

I splitted the template in part1 and part2. They are located in the parent directory.

if I use:

find . -name "*.txt" -print | xargs sed -i '1r ../part1.txt'

it inserts part1.text at the beginning of the file.

find . -name "*.txt" -print | xargs sed -i '$r ../part2.txt'

It inserts part2.txt at the end of the file.

BUT it doesn't work with files that contain a space in the filename.

Edit: I found the solution that worked best for me. See the initial post for it.

i see you already figured it out while i was comming up with a solution, so here is my solution anyway:

a simple bash script:

#!/bin/bash
for f in content_files/*; do
	cat template1 "$f" template2 > content_fixed/"${f/content_files\//}"
done

so you need to have template1 and template2 in the same folder as the script, they are the before and after parts.
then you need to have 2 folders in the same folder as the script, "content_files" and "content_fixed", and you put a copy of all your existing content.txt files in the "content_files" folder and then run the script and the "content_fixed" folder should have what you want.

that was a terrible explanation but i think you get the point.
