[Bug 58507] New: Cygwin in Wine cmd "find . -iname '*.exe'" breaks but "find Downloads -iname '*.exe'" works
http://bugs.winehq.org/show_bug.cgi?id=58507
Bug ID: 58507 Summary: Cygwin in Wine cmd "find . -iname '*.exe'" breaks but "find Downloads -iname '*.exe'" works Product: Wine Version: 10.11 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: wineryyyyy@gmail.com Distribution: ---
Running Cygwin's find inside wine cmd using ./ or ../ doesn't work but specifying a directory name does work:
z:\home\any\Downloads>find . -iname *.exe
find: paths must precede expression: `bogus_test_0.exe' find: possible unquoted pattern after predicate `-iname'?
z:\home\any\Downloads>find ../Downloads -iname *.exe
find: paths must precede expression: `bogus_test_0.exe' find: possible unquoted pattern after predicate `-iname'?
z:\home\any>find Downloads -iname *.exe

Steps to reproduce: 1. Download and install cygwin via wine explorer 2. SET CYGWIN_HOME=c:\cygwin64 3. SET PATH=%CYGWIN_HOME%\bin;%PATH% 4. find . -iname *.exe 5. find Downloads -iname *.exe
Emacs depends on cygwin's find working to support the most basic vital operations for finding file names and grepping patterns within files in order to be supported on Windows thus Wine.

--- Comment #1 from Stian Low wineryyyyy@gmail.com --- Previous efforts involving Cygwin were mixed between: 1. Getting Wine to work in Cygwin 2. Getting Cygwin to work in Wine
This issue is about 2. Getting Cygwin to work in Wine. https://gitlab.winehq.org/wine/wine/-/wikis/Cygwin-and-More#cygwin-in-wine
The primary reason to get Cygwin working in Wine is to get Emacs running in Wine as well as it does in Windows which works about as well as Linux allowing for it to be used almost exclusively between both systems in a very consistent manner.
Wine dev efforts may benefit from having Emacs hacking environment available for additional debugging capabilities.

--- Comment #2 from Alexandre Julliard julliard@winehq.org --- It sounds like *.exe was expanded by the shell because you have an exe in that directory. You'd need to quote the pattern, as find helpfully suggested.

Thanks Julliard. You are correct. Somehow I missed that it does indeed work for wine cmd by quoting "*.exe"
It doesn't work for emacs eshell however but that is not unusual for eshell since it does an extra layer of expansion.
I'll consider the wide side of the issue resolved and fix the remaining issues on emacs side.

--- Comment #5 from Stian Low wineryyyyy@gmail.com --- As final wrap-up with a solution to the emacs side bugs:
This form of find works for Emacs eshell: find . ( -iname *.exe ) -exec ls -ld {} ;
It is supported by: SET CYGWIN_HOME=c:\cygwin64 SET PATH=%CYGWIN_HOME%\bin;%PATH%
c:/cygwin64 [255] $ which find c:/cygwin64/bin/find.exe
Cygwin's find supports Emacs M-x find-name-dired which provides path list buffer used to conveniently navigate a file system.
For future reference here's some results of eshell find:
c:/cygwin64 $ find . ( -iname *.exe ) -exec ls -ld {} ; Cygwin WARNING: Couldn't compute FAST_CWD pointer. This typically occurs if you're using an older Cygwin version on a newer Windows.

Luckily the FAST_CWD doesn't break Emacs M-x find-name-dired either. Here's the buffer produced by Emacs M-x find-name-dired which supports actions per item consistent with Linux and Windows.

So far FAST_CWD seems largely be ignorable as a red herring of Cygwin integration problems.

--- Comment #6 from Stian Low wineryyyyy@gmail.com --- This key piece was missing from the last message which is required for Emacs M-x find-name-dired to work:
(setq shell-file-name "c:/cygwin64/bin/bash.exe")
Write it to ~/.emacs so that future Emacs sessions are automatically mapped to Cygwin environment.
Here's a a more complete list of relevant parts in my ~/.emacs that support mapping Cygwin and MinGW environments:
(setq shell-file-name "c:/cygwin64/bin/bash.exe") (setenv "CYGWIN_HOME" "c:/cygwin64/") (setenv "PATH" (concat "c:/cygwin64/bin;" (getenv "PATH"))) (setq exec-path (append '("c:/cygwin64/bin") exec-path )) (setenv "PATH" (concat "c:/x86_64-15.1.0-release-win32-seh-msvcrt-rt_v12-rev0/mingw64/bin;" (getenv "PATH"))) (setq exec-path (append '("c:/x86_64-15.1.0-release-win32-seh-msvcrt-rt_v12-rev0/mingw64/bin") exec-path ))
