Lines that start or end with 'ta'?

Question

bash

Hello.
Need to find lines in the file that start or end with 'ta'.
Separately, I can do this:
1) starts: grep "^ta" file.txt
2) ends: grep "ta$" file.txt
But how to put it in one expression?
Thanks in advance.

Answer 1

grep -P "(^ta|ta$)" test.txt
