Example :
./script >> log.txt
log.txt content :
1 - 2 - 3 _ 4/ 8
a - b , c - d/ 9
Before appending to file, I would like to extract the last number and then log it to the file.
log.txt new content should have :
8
9

`./script | awk '{print $NF}' >> log.txt`. – oguz ismail Jun 09 '21 at 11:27

@fashuai : _extract the last number_ : So if the input line is `AB C 25 DX` it means that the logfile should contain `25`, right? – user1934428 Jun 09 '21 at 11:28
