This set of commands will rip a dvd title using a 2 pass mencoder xvid encode. It will provide a great quality rip. It will rip as close to 700MB as possible. (note the bitrate of -700000)
Enjoy!

The platform-agnostic version of https://www.commandlinefu.com/commands/view/25276/compute-newest-kernel-version-from-makefile-on-torvalds-git-repository because macOS doesn't have wget installed
You can use wildcard with rpm search but you have to do 2 things:
1. use "-a" switch (means "all") with query ("-q") switch - argument is a pattern to use while searching for package names of all installed packages
2. protect wildcards, so that shell could not eat them - escape it with backslash ("\") or enclose all pattern between apostrophes ("'"):
$ rpm -qa 'co*de'
As you can see above it is possible to insert wildcards into middle of the pattern.
If you want, you can add "-i" or another rpm query options, "-i" will print package information for all installed packages matching pattern.
makes more sense to customers XD
