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 can handle this easily....

string="ata-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);worker-bin-4.5.1;worker-conf-4.4.1-c(kuh)-win2"

echo $string | sed "s/^.*divider-bin-\([0-9.]*\).*/\1/"
1.4.4

There are a few other things you can do to tighten it up... such as stop grabbing the version number when you reach the ";"

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