Hi,

Need a quick shell script or sed command that will change the ip address from one ip to another in every zone file in the dir /etc/named.d

Also need a script that will change the ip address from one ip to another in my apache conf file.

I was able to find and replace the ip address in the apache conf file with sed but could not figure out how to make it write the whole file with changes to a new file or save it to the existing file.

If you have a suggestion, please be very specific. I am still fairly new at linux.

Thanks for your help.

Here's how you would change the ip for one file:

sed -e "s/192.168.1.1/192.168.5.1/" originalfile > tempfile
mv -f tempfile originalfile

Adding a loop to do every zone file isn't that much harder.

Thanks Mik,

The code works perfect!

Are you up for helping me with the loop code that will look in every file of one dir for ip address changes. I have a lot of zone files and would hate to do it with vi.

Thanks again.

#!/bin/ksh
#Make sure you run this script from the dir where the files to change are.
#Pass the origional IP as the first argument and the new IP as the second.
if [ "$1" = "" -o "$2" = "" ]; then
echo "Usage: $(basename $0) <Origional IP> <New IP>"
exit
fi
echo "Origional IP = $1"
echo "New IP = $2"
for FILE in $(find . -type f); do
if $(grep -q "$1" $FILE); then
echo "Changing file: $FILE"
sed -e "s/$1/$2/g" $FILE > /tmp/newfile.tmp
if [ $? -eq 0 ]; then
#Make a copy of the origional file in case something goes wrong.
cp -f $FILE $FILE.bak
mv -f /tmp/newfile.tmp $FILE
fi
fi
done
echo "Done... check results then delete files with .bak extension"
