Answer 1

To get the latest tag only on the current branch/tag name that prefixes with current branch, I had to execute the following

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags --abbrev=0 $BRANCH^ | grep $BRANCH

Branch master:

git checkout master

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

master-1448

Branch custom:

git checkout 9.4

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags 
--abbrev=0 $BRANCH^ | grep $BRANCH

9.4-6

And my final need to increment and get the tag +1 for next tagging.

BRANCH=`git rev-parse --abbrev-ref HEAD` && git describe --tags  --abbrev=0 $BRANCH^ | grep $BRANCH | awk -F- '{print $NF}'
