In Linux, how do I go through each file and do a replace?

Question

Suppose I want to go through each file (recursively too), and replace everything with:

{{ MEDIA_URL }}

with:

{% media_url %}/

What command can I run in Linux to replace the former with the latter, in all my files, recursively?

Answer 1

How about a sed solution...

find ./ -type f -exec sed -i 's/{{ MEDIA_URL }}/{% media_url %}\//g' {} \;

Updated: added /g as per a commenter suggested

Updated: somehow unicode chars got copied in there

Answer 2

As much as possible, I use xargs instead of -exec . With a -exec , you'll have one process launched for each file while with xargs you will have only one process. You must use the sed option -s for that. This command is faster when you have several files:

find ./ -type f | xargs sed -s -i 's/{{ MEDIA_URL }}/{% media_url %}\//g'
