unix find command on cmder.exe in windows

Simplest solution is to create an alias to the find executable within the cmder installation folder:

λ which find
/c/WINDOWS/system32/find
λ find --help
FIND: FIND: Parameter format not correct
λ alias find=C:\Files\Programs\cmder\vendor\git-for-windows\usr\bin\find.exe $*
λ find --help
Usage: /usr/bin/find [-H] [-L] [-P] [-Olevel] [-D help|tree|search|stat|rates|opt|exec] [path...] [expression]

May I suggest you also try out Cygwin where, among other things, find works out of the box. That is what I used to ascertain the location of the cmder-supplied find.exe.

Kudos to @Bob and @AFH for their insightful comments, and to @Lưu Vĩnh Phúc for suggesting another dead-simple solution:

rename the *nix find to another name like fnd.exe

This might actually be preferrable over creating an alias, because cmder aliases don't work in Windows 10 unless Use legacy console is selected in cmd properties (see how to do it).

Cmder\vendor\git-for-windows\usr\bin is added to the PATH by Cmder\vendor\init.bat. Unfortunately, it's added at the end of the PATH, so Windows's find.exe is found first.

Fortunately, it's easy to fix. Just add this line inside Cmder\config\user-profile.cmd:

set "PATH=%GIT_INSTALL_ROOT%\usr\bin;%PATH%"
