How to add one block of text to the end of a file in multiple files?

Question

vim

There is a multilingual project in which it is necessary to add or change some text over time. Localization is tied to the English text, so when the English text changes, you have to change this block in all localization files.
Is it possible in vim to append text to the end of a file in multiple files at the same time?

Answer 1

For example:
* bufdo - for all open buffers (you can use argdo, tabdo, windo)
* execute - execute the command
* normal - "normal" mode commands
* G - go to the end
* p - paste the text from the buffer (copied by the y command)

Answer 2

echo "your text here" | tee -a *.txt
