Not sure if this is relevant, but while going over old bugs I noticed this: Bug in 'ls -FQ': incorrectly quoted characters http://bugs.gnu.org/29832 Which reports incorrect quoting of "@" as "\@" and also mentions "ls -b", and had a pending patch which was never committed. regards, -assaf

That's right, we need another way to escape classifier characters with -bF,
since the current method is clearly wrong.
Let's use ""= instead, as it's valid ISO C. In other words, where we currently
do this:
$ python -c "import socket as s; sock = s.socket(s.AF_UNIX); sock.bind('b')"
$ touch b= b=x
$ ls -bF
b= b\= b\=x
the last command should output this instead:
b= b""= b=x
This works because in ISO C "b""=" is equivalent to "b=". We should do this only
with characters at the end, because it's not needed elsewhere and the "" is
annoying.

Actually it seems that the meaning of "metacharacter" is ambiguous.
In bash, & is regarded as a metacharacter:
metacharacter
A character that, when unquoted, separates words. One of the
following:
| & ; ( ) < > space tab newline
> '=' is a shell metacharacter after 'set -k' in Bash.
It's a special character, but not a metacharacter (see above).
But then I agree on the need for quoting, if particular shells
are taking into account.

Not with "ls -bF": the quoting in a\=b&c is inconsistent.
Just like =, & should be quoted. Or = shouldn't be quoted
(see below).
> -b means to quote for C strings, not for the shell.
Hmm, yes... The issue here is that -b was actually changing the
quoting style, hence my confusion on this point. That's a bug in
the ls man page, which does not say so:
-b, --escape
print C-style escapes for nongraphic characters
The info manual is OK:
‘-b’
‘--escape’
‘--quoting-style=escape’
Quote nongraphic characters in file names using alphabetic and
octal backslash sequences like those used in C.
> If you want to quote for the shell, try

That's already the default. Actually, the confusion comes from the
ls man page.
On the behavior, there's still the issue concerning = and &.

Moreover, while & is not a metacharacter, it is a special character that should be quoted for practical reasons. In particular, this inconsistency with -bF makes a\=3Db&c unusable by copy-paste, as a\=3Db&c can't be used directly in a shell command, and 'a\=3Db&c' is not OK either. Note: Such filenames with =3D and & can be produced by "wget -r". --=20 Vincent Lef=E8vre <vincent@HIDDEN> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
