I am using hostname -I to list all of the IP addresses for a host. I then processes this list under the assumption that it is space delimited. Is this assumption valid in general? I see that the man page says that you shouldn't make assumptions about order, but can I assume that

  • This command and option is available on all major distributions of linux
  • The output produced by this command is always space delimited

Thanks!

No, you can't, at least not until you sufficiently limit "all major distributions of linux". Older versions don't have this option at all and e.g. the BSD/MacOS version is completely different.
