How to remove a template from all files?

Question

linux

Good afternoon. There are about 1000 almost identical html files. I need to remove a specific piece containing text and tags from each. I cut it manually from one file and saved it as remove.txt. How can I use this file as a template and cut it out of the rest of the files?
An important point: the piece to be cut does not begin with a new line and does not end with the end of the line either.

Answer 1

Write a script that will cut out the code you need

Answer 2

The string variable will receive a string from the file (did not check for complex constructions (the test was a short phrase)), then the loop will go through all the files in the specified folder and with each iteration write the file name to the var variable, sed -n will mute the output to stdout , by pattern from string will remove the lines in the file and write a new file without those lines. It works on the test bench, the key point remains what string will receive.

#!/bin/bash
string=$(cat /путь_до_файлов/remove.txt)
for var in $(ls -1 /путь_до_файлов)
do
        sed -n "/$string/d" $var > /путь_до_новых_файлов/$var
done
