Date: Sat, 24 Aug 2002 21:02:10 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Aha. I figured it out, and it looks like Cygwin's ash might not be posix compliant. Tilde expansion is required by Posix; see http://www.opengroup.org/onlinepubs/007904975/utilities/xcu_chap02.html#tag_ 02_06_01 Looking at the source for the ash used in Cygwin, it looks like tilde expansion is disabled! The Makefile.am in http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/rele ase/ash/ash-20020731-1-src.tar.bz2 defines SMALL by default, which shuts off tilde expansion. That would explain my result (though not why tilde works from the ash commandline; curious). Am I correct? It's a little suprising to find Cygwin doesn't use a Posix-compliant shell... - Dan -----Original Message----- From: Dan Kegel To: 'Michael A Chase '; Dan Kegel; ''cygwin@cygwin.com' ' Sent: 24.08.2002 20:20 Subject: RE: faq: why doesn't tilde expansion work in shell scripts in cygwin? Say, it says in http://www.opengroup.org/onlinepubs/007904975/utilities/xcu_chap02.html# tag_02_06_01 and http://www.opengroup.org/onlinepubs/007908799/xcu/chap2.html#tag_001_006 _001 that tilde expansion is required. Yet ash claims it is posix compliant. Hrm. Somebody's wrong somewhere... maybe ash is only compliant to an outdated posix version? - Dan -----Original Message----- From: Michael A Chase To: Dan Kegel; 'cygwin@cygwin.com' Sent: 24.08.2002 19:49 Subject: Re: faq: why doesn't tilde expansion work in shell scripts in cygwin?

If it is /bin/sh, ash doesn't do tilde expansion. -- Mac :}) ** I normally forward private questions to the appropriate mail list. ** Ask Smarter: http://www.tuxedo.org/~esr/faqs/smart-questions.html Give a hobbit a fish and he eats fish for a day.
