Subject: multi-digit file descriptors
Date: Wed, 11 Feb 2015 17:26:37 +0100 [thread overview]
Message-ID: <20150211162637.GA9083@xvii.vinc17.org> (raw)
Contrary to bash and mksh, zsh doesn't support file descriptors with
multiple digits. Considered the following file "redir".
----------------------------------------
( echo foo >&9; ) 9>my_file
cat my_file
( echo bar >&10; ) 10>my_file
cat my_file
----------------------------------------
xvii% bash redir
foo
bar
xvii% mksh redir
foo
bar
xvii% zsh redir
foo
redir:4: parse error near `10'
The behavior of dash and ksh93 is similar to zsh. But is there any
reason?
BTW, POSIX doesn't seem to restrict file descriptors to 1 digit.
