There are no duplicate *.exe commands. All Cygwin executables contain
the exe extension as Windows prefers. Cygwin tries to make things
easier by mapping "cat" to "cat.exe", for example, which is why it may
look to you like there are both in the Cygwin environment. But look at
'c:\cygwin\bin' in the Explorer and you'll see all the commands have the
.exe extension. If you get rid of one, you get rid of the other since
they are the same. Now, to anticipate your next question,
'/usr/bin/cat.exe' and '/bin/cat.exe' are not duplicates either. See
the results of typing 'mount'.
=======================
i'm not talking about deleting any files, just deleting duplicate *.exe
commands from my command hash, so they don't auto-complete when i press
<TAB>. the *.exe commands would be there (and be available if called), i
just wouldn't have to look at them when i tab-complete.
ls -ilh `which cat cat.exe`
that tells me that the two commands are hard-linked; they share the same
inode. it seems the same way for all of the commands that appear in my
PATH with and without a ".exe" suffix.
so the question remains: is it "safe" to delete all *.exe files from my
command hash? or should i first check for the same command, in the same
place, without the ".exe" suffix?
