Hi,

Looking for some tips on how to build a find and replace shell script I can use to mass modify my named.conf file. I need to change out an ip address in over a hundred places in the file.

Okay I start like this: for fl in named.conf but then what?

On the fly here ~ so use caution - example current ip is 72.96.52.127 and your named.conf file resides in the etc directory.

Code:

#!/bin/sh
# you must be root to run this script

# Lets store some user input to variables
echo ""
cd /etc
echo "Enter your new ip address" 
read var1
echo "I've logged your ip addy $var1"

for fl in named.conf; do
mv $fl $fl.old
sed "s/72.96.52.127/$var1/g" $fl.old > $fl
rm -f $fl.old
done

echo " ***************************************************************"
echo " .... Your file updates are complete"
echo " ***************************************************************"

exit
