looking for a space at the beginning of file contents

vonshavingcream · 11-21-2011, 10:00 PM

so i'm working a php site. about 3 days ago some image display scripts stopped working.

I discovered today that it is because a space is being output at front of every page.

I have a lot of php files since I am working in an MVC framework.

How can I check every file in the root directory and see if the first char is a space?

Code:

 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

it might be hard to see above but just before the <!DOCTYPE there is space.

I have hunted for the thing for 3 hours.

any suggestions on how to find it?

Thanks,
C

You can grep for it:

Code:

grep ^\ \<\!DOCTYPE *.html

or in multiple subdirs:

Code:

find "*.html" -exec grep -H ^\ \<\!DOCTYPE *.html \;

Same to find and replace:

Code:

find -name "*.html" -exec sed -i s/^\ \<\!DOCTYPE/\<\!DOCTYPE/ {} \;

Use with extreme care, sed edits the files in place. One typo and you can recreate a zillion files!
