Re: exe in path directory, "command not found"

I've added /cygdrive/c/program\ files/notepad++ to my path in .bash_profile,
double checking with echo to make sure that the directory is in the path. But
when I type "notepad++.exe" or "notepad++" I get "bash: notepad++: command
not found". I did restart the terminal before testing to make sure that
.bash_profile was loaded and path was updated. Is there something I'm doing
wrong here or is this a bug?

As per René & Eliot but anyone who uses Notepad++ a lot from Cygwin might be
interested in the attached script which can be put in /etc/profile.d/ or
sourced from your .bashrc. It creates a shell function 'npp' that parses the
command line and translates pathnames to Windows format before passing to
Notepad++. It adds a --wait argument to cause the caller to wait on Notepad++
instance exiting before returning.

The second script ('npp') provides a wrapper around the first for POSIX programs
looking for an executable e.g. git commit message editor etc.

I've done the same for kdiff3 if anyone wants them.
