Small script for primes (SOLVED) - Page 2

pepi37 · 2015-05-15, 15:18

Standard output looks like
92*10^542048-1 is not prime. RES64: DEADBEEFDEADBEEF. OLD64: EE08834052D0214E Time : 990.560 sec.

What I need to do when this output is copied to results.txt is automatically crop to
( OLD64: EE08834052D0214E Time : 990.560 sec. is automatically removed)

92*10^542048-1 is not prime. RES64: DEADBEEFDEADBEEF.

92*10^542048-1 is not prime. RES64: DEADBEEFDEADBEEF.

This command should match the pattern you want.

Code:

echo '92*10^542048-1 is not prime. RES64: DEADBEEFDEADBEEF. OLD64: EE08834052D0214E Time : 990.560 sec.' | grep -o -e '^[^.]* is not prime. RES64: [[:upper:]]\{16\}.'

If you want to know more about regex in grep, the GNU grep manual is great. If you need more text processing power, then perl is your Swiss-army chainsaw.
