Follwing is the simple shell script to auto modify your httpd.conf. Modify path in script accordingly


#for adding a line, append the line in httpd.conf
echo "ServerName XXXXX" >> httpd.conf
#for replacing, use sed or grep command, using grep
grep -v "DocumentRoot" httpd.conf >httpd.conf.tmp
echo "DocumentRoot your_document_root_path" >>httpd.conf.tmp
mv httpd.conf.tmp httpd.conf

Use Vi editor:

find . -type f -exec sed -i -e 's/DocumentRoot/ServerName XXXXX/g' {} \;
