Java Parameter Expansion with regular expression

Hello experts,

I am exploring parameter expansion, and trying to cut the fields in a URL.

Following is the requirement:

I have

// abc.nnt /dir1/dir2/dir3/dir4/somefile.java

What i need to get is the path after dir3, and dir3 will be passed.
output that i need is dir4/somefile.java.

I am trying to use like
path="https://abc.com/dir1/dir2/dir3/dir4/somefile.java"
showseason=${path#https://abc.com/}
am getting /dir1/dir2/dir3/dir4/somefile.java as the output.
Please let me know how will the required output.


Thanks in advance.
