I am trying grep only the numbers from the end of the string until any other char, so from example: "Version 1.2.34" Will give me '34' to variable $minor and 'Version 1.2.' to variable $type

I manage to

minor=$(grep -Eo '[0-9]{1,24}')

but this gives me ALL numbers.

CodePudding user response：

Using pure bash:

s="Version 1.2.34"

minor="${s##*[!0-9]}"
type="${s%$minor}"

declare -p type minor
declare -- type="Version 1.2."
declare -- minor="34"
