Hello everyone,
I have a question about how to translate the meaning of ".+?". Please
see the examples below:
SASI_Hs01_00205058 HUMAN NM_005762 857 MISSION® siRNA 2
140.00
I want to get number"857", I found the command below works:
perl -ne 'if (/(SASI\w+)(.+?)\s(\d+)\s/) { print "$3\n"; }'
but ".+" or ".*"doesn't work. I don't know why "?" is so important?
Thank you!
Xi
