When I try to find a specific byte with grep not using pipe I get some output:$ grep -aboP \\x55 bigfile510:U1049086:U1049598:UBut when a pattern is supplied via pipe then there is a memory exhausted error:$ echo \\\\x55 | grep -aboPf - bigfilegrep: memory exhaustedWhy does it happen and how to make it work?
grep: memory exhausted on big file when using pipe
