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

Answer 2

This works for me...

<\?php | \?>

If you need to use in in a sublime-settings file or something like that which doesn't like forward slashes, you might have to add an extra slash for each of them like so...

<\\?php | \\?>

Hope that helps!

Answer 3

Using notepad++ you can replace easily all documents at the same time, drap and drop that folder of files and press CTRL + R, also you can use Regex

Answer 4

The problem here is normal grep doesn't match multiple lines. So, I would install pcregrep and try the following command:

pcregrep -rMl '\?>[\s\n]+\z' *

This will match all files in the folder and subfolders (the -r part) using PCRE multiline match (the -M part), and only list their filenames (the -l part).

As for the pattern, well that matches ?> followed by 1 or more whitespace or newline characters, followed by the end of the file \z. I found though, when I ran this on my folder, many of the PHP files do in fact end with a single newline. So you can update that regex to be '\?>[\s\n]+\n\z' to match files with whitespace over and above the single \n character terminator.

Lastly, you can always use od -c filename to print unambiguous representation of the file if you need to check its exact character sequence ending.

Answer 5

grep '?> ' *.php? Of course, it may not be a space and could be a linebreak or a tab, so you may want to try other characters.

Answer 6

This worked for me to find white spaces before php files

find -name '*.php' | xargs grep -Pz '\?>[\s]+$' -l
