Find extra space / new line after a closing ?> (php tag)

Question

So I have a space/new line after a closing ?> (php tag) that is breaking my application.

How can I find it easily I have 1000 of files and 100000 lin

Answer 1

use perl;

perl -0777 -i -pe 's/\s*$//s' *.php

• -0777 will slurp he whole file (-0 will be ok too)
• -i - inplace editing, so the file will be replaces with the result
• -p print lines
• -e perl expression

s/\s*$//s - treat all lines as a single line and substitute any space at the end to nothing
