--- Begin Message --- Subject: 23.1; dired cannot find gunzip with Z; Windows Date: Wed, 4 Nov 2009 08:56:09 -0800 when using emacs on Windows, when in dired, when i press Z on a file that's gzip compressed, emacs tells me:
'gunzip' is not recognized as an internal or external command,

the problem is apparently that emacs won't recognize the gunzip shell script without the exe suffix. (the gunzip is in the same dir as gzip.exe) But if i rename gunzip to gunzip.exe, but Windows complain that the file is not a exe format.

extra detail:

when i do
(executable-find "gzip")
emacs says
"c:/cygwin/bin/gzip.exe"

and
(executable-find "gunzip")
says
nil.

the gunzip exists at
c:/cygwin/bin/gunzip
which is a shell script that calls gzip -d.

Same problem when starting emacs with -Q.

GNU Emacs 23.1.1 (i386-mingw-nt6.0.6002) of 2009-07-29 on SOFT-MJASON

I'm reporting this as a bug, but tips on solving this on my machine also would be appreciated. Thank you.

I'm thinking, shouldn't emacs's dired simply look for gzip and call it with gzip -d, instead of looking for the gunzip program? That seems to me simpler and more reliable.

No, this error message comes from the OS, not from Emacs.  Windows
does not support invocation of Unixy shell scripts, and thus Emacs,
being a native Windows program that uses Windows APIs, cannot run
them.

To make this work, create a Windows batch file unzip.bat which invokes
gzip.exe with the -d switch.  Then Emacs will find it and do what you
want.

I'm closing this bug.
