Regex to remove the specific word from URL

In Dynatrace, there are the URLs which are containing the a word which is dynamic. Want to remove that dynamic word from the URL using regex

Below are the different urls

Expected output

I'm able to manage this regex

You could use the 2 capturing groups and match the underscore part after matching a forward slash

^(\S+/)[^\s_]+_[^\s_/?]+(.*)
  • ^ Start of string
  • (\S+/) Capture group 1, match 1+ times a non whitespace char followed by /
  • [^\s_]+ Match 1+ times any char except a whitespace char or _
  • _ Match literally
  • [^\s_/?]+ Match 1+ times any char except a whitespace char, _, / or ?
  • (.*) Capture group 2 Match 0+ times any char except a newline

Regex demo

In the replacement use the 2 capturing groups, for example $1$2

If you want to match country codes and you know that they for example consist of chars a-zA-Z you could make the character class more specific

^(\S+/)[A-Za-z]+_[A-Za-z]+(.*)

It seems that the first portion is fixed, and you're trimming everything after a '/' or '?'. Given that, perhaps you want something like:

s/(\/asd\/fdsadx\/sadsa\/)[^/?]+(.*)/\1\2/

This will capture the head in \1, ignore a group of characters that are not either '\' or '?', and capture the tail in \2.
