1.7.7 ln .exe magic

2010-09-15 Thread Rolf Campbell

test case---
From bash, in an empty directory:
$ ln /bin/ls t
$ ls
t.exe

Why does the resulting hard link have a '.exe' suffix on it?  I thought 
that cygwin .exe magic was only appending when listing a file?

If the original file ends in .exe, then cp tries hard to make the target 
also end in .exe.  The .exe magic for invoking 'ls' (instead of ls.exe) 
will therefore let you also invoke 't' (instead of t.exe), while still 
letting you run .\t from cmd (where the lack of a .exe suffix would 
break that attempt).  So the .exe magic is more than just when listing a 
file.

Greetings, Rolf Campbell!

It's quite expected.
If source has .exe, the target will, too, for transparent compatibility.
