Subject: printf and POSIX compliance
Date: Tue, 4 Feb 2003 16:44:25 +0100 [thread overview]
Message-ID: <20030204164425.A192@pcchazelas.free.fr> (raw)
Hello all, and thank you for the very good job
I read at
http://www.opengroup.org/onlinepubs/007904975/utilities/printf.html
that, according to POSIX:
3- In addition to the escape sequences shown in the Base
Definitions volume of IEEE Std 1003.1-2001, Chapter 5, File
Format Notation ( '\\' , '\a' , '\b' , '\f' , '\n' , '\r' ,
'\t' , '\v' ), "\ddd" , where ddd is a one, two, or
three-digit octal number, shall be written as a byte with the
numeric value specified by the octal number.
So
printf '\377\0377' | od -c
should return:
0000000 377 037 7
0000003
zsh printf gives:
0000000 \ 3 7 7 377
0000005
zsh man pages says that sames sequences as for echo are
recognized. That's not what POSIX requires.
Note that neither bash nor GNU printf behave better.
The "printf '%b' '\0ooo'" is OK though.
