The Misadventures of Penoi

Find and replace string recursively

find /home/penoycentral/whichfolder -type f -print0| xargs -0 sed -i 's/oldstring/newstring/g'

If you want to make sure that you are changing which, use the old grep first

find /home/penoycentral/whichfolder -type f -print0| xargs -0 grep -i oldstring

Example Problem: Change /etc/bind to /var/named/master in named.conf

Just print what will be changed

 sed -n 's/\/etc\/bind/\/var\/named\/master/p' named.conf 

to change:

 sed -i 's/\/etc\/bind/\/var\/named\/masterr/g' named.conf 

Change double qoute to single qoute

sed -i "s/[\"]/\'/g" some-file.pp
