sed search could not be complete

Hi All,

I have a parameter as below

make_target_dir_name="/buildanddeploy/BUILDS/build.22/db/Db-1.17.9/SQL"

Now after writting sed I want only the output should display SQL by ripping /buildanddeploy/BUILDS/build.22/db/Db-1.17.9/ out from the input make_target_dir_name

my sed is not working

echo $make_target_dir_name | sed "s_.*Db-*[0-9]\+__")

--> Not working showing me

.17.9/SQL

How can I achieve this? this should dynamically take all the numbers out and show me only folders after the number.

why sed ?

echo $make_target_dir_name | awk -F/ '{print $NF}'

give

SQL

thanks ...but I can't rely on this
because my make_target_dir_name can have multiple subfolders and file names underneath.
e.g.

/buildanddeploy/BUILDS/build.22/db/Db-1.17.9/SQL/v1.16/db.changelog-update-v1.16.xml

in this case I want only

SQL/v1.16/db.changelog-update-v1.16.xml

Hence I want to display the string after the Number, this number is not static after every release the number will change.

try:

echo $make_target_dir_name | sed -n s'/\(.*Db-[0-9]\.[0-9][0-9]\.[0-9]\/\)\(.*\)/\2/p;'

thanks
from this I made little dynamic way to serve my purpose

echo $make_target_dir_name | sed -n s"/\(.*Db-[0-9]\+\.[0-9]\+\.[0-9]\+\/\)\(.*\)/\2/p;"
