How can I delete all lines after a specific string from a number of files

Question

I have n files, like:

file1:

Hannah
Lars

Test 123
1aaa
2eee

file2:

Mike
Charly
Stephanie
Earl

Test 123
3ccc
4ddd
5eee

I want to remove all rows after "Test 123" from all n files. The number of rows to delete varies between files.

There's a very similar question How can I delete all lines before a specific string from a number of files in which sed -i.bak '1,/Test 123/d' file* works perfectly, but how can I do it for all lines after a specific string?

Thanks!

Despite the comments and closed question, nothing in other threads worked. Figured out a solution:

for FILENAME in * ; do sed -i.bak '/Test 123/q' $FILENAME ; done

I suggest to use only `sed -i.bak '/Test 123/q' *`. – Cyrus Aug 07 '22 at 16:59
Or even `xargs`! https://stackoverflow.com/questions/13939038/how-do-you-run-a-command-eg-chmod-for-each-line-of-a-file – F. Hauri - Give Up GitHub Aug 08 '22 at 11:35
