Please do not malign a perfectly good tool just because you may be using it
incorrectly, be that dos2unix, perl, regex, or anything else.
Or demonstrate how you yourself use it so that others can file a bug report
or issue a Pull Request.
Misinformation about any tool is not helpful to the OP or anyone else.
For what it's worth, dos2unix seems to work just fine on RHEL 8:
{ cat <<'eof'
grep PRETTY /etc/os-release
{ yum -y update && yum -y install dos2unix ; } >& /dev/null
echo -en 'hello world\r\n' | cat -vetn
echo -en 'hello world\r\n' | dos2unix | cat -vetn
eof
} |
docker container run -i --rm redhat/ubi8 /bin/bash
PRETTY_NAME="Red Hat Enterprise Linux 8.10 (Ootpa)"
1 hello world^M$
1 hello world$
Wishing you the best of health.
Regards,
- Robert
