Answer 4

+1 A:

#!/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" "{}" +;

Answer 5

A:

Here is my proposition. It assumes that your text to insert is in a file named mytextfile.

for file in ${fe}*; do
    awk '/!DOCTYPE/{printf"%s\n",text;}{print}' text="`cat mytextfile`" $file \
        > /tmp/out
    mv /tmp/out $file
done
