Replace text recursively

I’m in the process of moving from my gogs instance on git.icod.de to my gitea instance on code.icod.de In this process I’m migrating countless packages manually. It’s quite a lot of work. Often I need to replace “git.icod.de’ with ‘code.icod.de’ To do this on a Linux machine I use the following 1-liner:

grep 'git\.icod\.de/dalu/blogs' * -rl | xargs sed -i 's/git\.icod\.de\/dalu\/blogs/code.icod.de\/dalu\/blogs/g'

1	grep 'git\.icod\.de/dalu/blogs' * -rl \| xargs sed -i 's/git\.icod\.de\/dalu\/blogs/code.icod.de\/dalu\/blogs/g'

nginx: [emerg] unknown “tls1_3_early_data” variable

By Darko Luketic 19. October 2022 1 min read 1 Comment

If you’re getting this error message doing nginx -t or otherwise, for instance if you’re copy/pasting Mattermost’s nginx configuration, know that the line is

add_header X-Early-Data $ssl_early_data;

1	add_header X-Early-Data $ssl_early_data;
