I have many files with .abc extension and want to change them to .edefg I have a root folder with many sub-folders, so the solution should work -r recursively. find /the/path -depth -name "*.abc" -exec sh -c 'mv "$1" "${1%.abc}.edefg"' _ {} \;
I fixed it with the following commands: sudo dpkg –add-architecture i386 sudo apt-get update Then I could install ia32-libs just fine! https://bugs.launchpad.net/ubuntu/+source/ia32-libs/+bug/1016294/comments/27
