How to remove an unknown substring within strings, in a file?

Question

linux

Hello everyone,

there are different lines in the text file, including lines like:

SF:./var/src/routes/okta/logout.jsx
SF:./opt/src/routes/new/exit.jsx

you need to delete the text before src/ and before the colon to get

SF:.src/routes/okta/logout.jsx
SF:.src/routes/new/exit.jsx

Good luck,
Vadim
