I think the postinstall scripts are executed under the user's shell,
though. And we've used this construction a lot in those scripts.
Also, I believe that Tiger's tcsh mimics the POSIX behavior but
Tiger's bash does not. So even if we relied on scripts being
executed by bash, we would have trouble if the current bash is not
POSIX-compliant.

The \c was introduced by the Sys3 (later Sys-V) cretins. Unfortunately, SysV was adopted as POSIX, more or less. It's sad that we're losing the legacy means. :( -- Randal L.

There is a /usr/bin/printf for shells where it is not available as a builtin, so in tcsh printf works too, but it uses /usr/bin/printf. printf(1) behaves in a very similar way to the printf(3) function. You can, for example do: % printf "The current user is %s\n" $USER The current user is peter So, of course: % printf "foo" foo autoconf just switched to using printf instead of echo because its behavior is similar on all platforms where it is available, echo's behavior varies on different platforms (or in our case, on different versions of the same platform :-p).

You're completely right !
But {Compile,Install,etc...}Script's are always executed under (ba)
sh, no ?
(unless the maintainer specifies differently, knowing what he is
doing...)
similar issue with pogma's :

the doc cited is a bit painful to read through...
and 'man printf' doesn't show at all 9at first sight at least)
why the above construct should work... (as it does !).
But printf is a builtin, and `man bash` documents the construct
perfectly.

Re: [Fink-devel] echo -n now deprecated
The reason for the /bin has to do with behaviors of different shells in Tiger. Without writing /bin/echo, the 'echo' command is processed as a shell built-in, and the results are different for bash and tcsh. -- Dave On Dec 16, 2006, at 5:00 PM, Jean-François Mertens wrote: > I see coreutils is at version 6.7, vs 5.96 in fink. > If the maintainer were willing to update, I would hope the need for > the "/bin/" > to disappear ... ; there should be a way to write things > 'portably' (at least > across current versions of GNU and of Darwin...). > It is a bit of a shock to see coreutils behind darwin... > > JF Mertens > > On 17 Dec 2006, at 00:49, David R.Morrison wrote: > >> As mentioned on the new "preparing for 10.5" page on the fink wiki, >> echo -n is now deprecated in fink.

Re: [Fink-devel] echo -n now deprecated
I see coreutils is at version 6.7, vs 5.96 in fink. If the maintainer were willing to update, I would hope the need for the "/bin/" to disappear ... ; there should be a way to write things 'portably' (at least across current versions of GNU and of Darwin...). It is a bit of a shock to see coreutils behind darwin...

[Fink-devel] echo -n now deprecated
As mentioned on the new "preparing for 10.5" page on the fink wiki, echo -n is now deprecated in fink. I have edited the vast majority of packages where this occurs to conform to the new version. Instead of echo -n "string" one should now write /bin/echo "string\c" (See "man echo".) This makes our use of echo POSIX compliant, and is also compatible with current 10.4 usage. -- Dave - Take Surveys. Earn Cash.
