bash - Terminal sed into .command file

I have this script to remove the first 4 lines of every file in a folder if their extension is .txt.

I want to be able to place a file.command with this script in the same folder so I can just double click on it and execute it.

So I made a file with this:

#!/bin/bash

find . -type f -name "*.txt" -exec sed -i.bak '1,4d' {} \;

If I run the file I have all of my Mac txt files 4 lines removed :(

I thought the find . was meant to stay in the same folder ...

How do I fix it in order to have the command run ONLY in the folder the file.command is?

This code:

find . -maxdepth 1 -type f -name "*.txt" -exec sed -i.bak '1,4d' {} \;

actually works, the issue were:

1. The created file with the command wasn't made executable for that do:

   
   
   

   chmod +x file.command
   




2. Then run the command from the terminal with:

   
   
   

   ./file.command
