pathing issues script failure

[Randall R Schulz]

Scott,

You're re-inventing the wheel, here.

Learn about "cygpath", for starters.

Also, a new package called "cyg-wrapper.sh" was recently released. It's an 
attempt at a generic bridging script between Cygwin command interpreters 
and Windows-native programs. I have yet to evaluate it, so I can't tell you 
more than that it exists.

I've done similar things (in more specific form) to make access to the Java 
SDK tools accessible from Cygwin scripts in such a way that the same 
scripts would be useful on a Unix / Linux / POSIX system.


Here are some hints:

- Quote your variables extensively. Spaces in file name are far more common 
under Windows and latent lack-of-quoting bugs in scripts that originate on 
Unix systems will often become manifest on Windows (including under Cygwin).

- Don't put your class files at the root of a file system volume unless 
perhaps you have a file system volume dedicated to that purpose.

- Don't assume that all your top-level packages are "com." There are 
third-party tools that reside in other top-level package: "edu," "org," 
"gnu" etc.

- Chmod has a recursive option, "-R", that obviates the use of things like 
"find ... |xargs chmod ..."

- Windows is just as happy with forward slashes even in its native format, 
so save yourself the grief of using backslashes and stick to forward 
slashes throughout. Cygpath has a "mixed-mode" option "-m" or "--mixed" 
that converts to Windows format but uses forward slashes.

Good luck.
