grep non printable characters
Sometimes obvious things... are not so obvious. I always thought that it was possible to grep non printable characters but not with my GNU grep (5.2.1) version.
Code:
printf "Hello\tWorld" | grep -l '\t'
printf "Hello\tWorld" | grep -l '\x09'
printf "Hello\tWorld" | grep -l '\x{09}'
What am I doing wrong? |
