Bash Scripting: I want to open a set of .php files, and add line before html tag

I have a set of .php files in a folder, I want to add text just before these lines:

<!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" xml:lang="en" lang="en" >

What i want is to insert just before these lines in the html file. So just want to prepend that file before each docType declaration. However the DOCTYPE declaration is never on line 1, as there is loads of php lines before.

I have this current script (where FE is the folder containing all the scripts i want to edit):

for file in ${fe}*; do
      echo "$file"
done

Thanks,

Solution 
  • #!/bin/bash
shopt -s nullglob
text2add="my text to add"
for file in *.php
do
  if [ -f "$file" ];then
     sed -i.bak "/<\!DOCTYPE/ i $text2add" $file
  fi
done

    Or just simply 

    text2add="my text to add"
sed -i.bak "/<\!DOCTYPE/ i $text2add" *.php

    If you want to do it recursively

    find . -iname "*.php" -exec  sed -i.bak "/<\!DOCTYPE/ i $text" "{}" +;
