====== Manipulate File based on list ======
<code bash>
#!/bin/bash

File_line = list
Edit_file = httpd.conf

for i in $File_line; do

sed "s#DocumentRoot $i#DocumentRoot $i \\
php_admin_value open_basedir \"$i:/tmp\"#" $Edit_file

#sed -i.bak "s#DocumentRoot $i#DocumentRoot $i \\
#php_admin_value disable_functions \"exec,system,passthru,readfile,shell_exec,escapeshellarg,escapeshellcmd,proc_close,proc_open,ini_alter,dl,popen,parse_ini_file,show_source\"#" httpd.conf

==== sed to insert line after string match ====

  * -i will allow you to write to file and create backup
  * -e will allow for bash expression such as '\t' to be completed (tab insertion)

  * usage: '/pattern to find/a the text you want to add'

<code bash | quickinsert.sh>

sed -i.bak  -e '/type slave/a \\t masters { 71.167.42.205; } ;' named.conf
