Extract version number from a string

Question

I have a string with components and version numbers:

data-c(kuh-small1);divider-bin-1.4.4;divider-conf-1.3.3-w(1,16);storage-bin-1.5.4;storage-conf-1.5.0-w(1);

Answer 1

sed -n "s/.*;divider-bin-\([0-9][^;]*\);.*/\1/p"

infos is between ;divider-bin- and next ; and start with a digit. This is to ensur that no Other-divider-bin- or divider-bin-and-hex- will interfere with your request. Also, return empty string if not find. to be exhaustif (assuming version is only digit and dot)

sed -n "s/.*;divider-bin-\([0-9.]\{1,\}\)\([^0-9.;][^;]*\)*;.*/\1/p"
