I have a WordPress site and want to change first line of all php files recursively using bash. How should I do? I am not very familiar with bash.
Thanks!

What have you tried? Loop through files (stackoverflow.com/questions/14823830/…) and make your change...?ɴᴀᴛᴇ ᴅᴇᴠ– ɴᴀᴛᴇ ᴅᴇᴠ2014-02-20 10:12:49 +00:00Commented Feb 20, 2014 at 10:12

Change first line to some other line:
sed -i '1s/.*/changed line/' *.php
Adding a line before first line:
sed -i '1s/^/changed line\n/' *.php

While it worked, it also modified all the line endings in my files. In vim I see ^M at the end.
In order to modify the first line of the file, you can use this :
awk 'NR==1 {$0="what you want"} 1' *.php
You'll find more info here : bash: replace an entire line in a text file
Then to do it recursively, you can use a find first and then execute the awk command on every found file.
find . -name "*.php" -exec awk 'NR==1 {$0="what you want"} 1'
More info about the find command here : https://www.gnu.org/software/findutils/manual/html_mono/find.html#Scope
I used both above answers and executed the following:
find . -name "*.php" -exec sed -i '1 s/.*/<?php/' '{}' \;
So thanks both of you Theox and anishsane for your help
