Bash: extracting first or last N octets, paths, or domain from string with fixed separator
When parsing a string that is divided by a separator char, getting the first N values OR last N values is a common scenario when dealing with: IP address separated by periods, e.g. “10.11.12.13” File path separated by forward slash “/tmp/myfolder/subpath1/subpath2/subpath3” Fully qualified domain separated by periods “sub1.sub2.my.domain.com”
