[9fans] Frogs?

[Kare Nuorteva]

Hello,

I've bumped into frogs a few times while lurking on this list, but cannot make much sense out of it. Could someone please explain what is a frog in a filename?

Cheers,
Kare

chars that, by convention, convey information in-band when dealing with
files (e.g. '/'); they require quoting when used in file names.

It's many decades old, and not restricted to file names. It originally
referred to an unexpected non-ASCII character in a text file:
"There's a frog in my file!" It was sometimes put there by a buggy editor
or corrupt file system. By extension it's a
character, still usually unprintable (before Unicode fonts), that doesn't
belong in its context. It's a bit of a stretch to call "/" a frog,
but that's just the name of the array.

although this is all true, in the context of my comment needsquote() in libfmt is more relevant.

the rc shell has a well defined quoting convention, but this is not shared by awk or sed. Thus to    split the fields in du's output you need something that understands this convention, like the shell itself.

As an historical note the space character was once a frog. Rob told me that
he removed it from isfrog just to see if this broke anything. It didn't.
