Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : script to do this?

[BiggyMike]

is there a script that allows me to grep and replace IPS in the named/BIND DNS files and the httpd.conf file all at the same time?

You might have to write a small shell script to do it... If you can provide some of the paths and file names I could probably whip something up in a few minutes.

well httpd.conf is /usr/local/apache/conf/httpd.conf

named files are kept as /var/named/domain.tld.db

Here you go. This is untested! Make sure you try it out on some dummy files first. If it doesn't work, let me know.

HTTPDCONF="/usr/local/apache/conf/httpd.conf"

GREPIP=${1}
REPLIP=${2}

if [[ -z "${GREPIP}" ]]
    then
    echo "Usage:  ip.sh <grepped IP> (replacement IP)"
    echo "Replacement IP is optional.  If specified, it is the replacement pattern for <grepped IP>"
    exit 1
fi

echo "Testing httpd.conf for ${GREPIP}..."
grep -q "${1}" ${HTTPDCONF} 

if [[ ${?} -ne 0 ]]
    then
        echo "Nothing found in ${HTTPDCONF}."
    else
	echo "${GREPIP} was found in ${HTTPDCONF}"       
        if [[ -n ${REPLIP} ]]
        then
            echo "Replacing ${GREPIP} with ${REPLIP} in ${HTTPDCONF}"
            sed -ie "s/${1}/${2}/g" ${HTTPDCONF}
        fi

echo ""
echo "Testing domain.tld.db for ${GREPIP}..."
grep -q "${1}" ${BINDCONF} 

if [[ ${?} -ne 0 ]]
    then

I realized I made a very minor boo-boo by hard-coding the file names in the echo statements. Went to fix it, but apparently WHT bans edits after 15 mins.

I did test it this time and works like a charm. Enjoy!

Wow thanks a lot!
