Hi,

I can run tar commands just fine inside a cygwin terminal window, but my app needs to issue a cygwin command line tar and I can NOT make it work. I've tried all kinds of quoting and escaping, but I can't figure it out!

Even this one (works great in cygwin window):
tar -tvf dld.gz

...but fails when issued like this:
c:\cygwin\bin\bash.exe -c /usr/bin/tar -tvf dld.gz
/usr/bin/tar: You must specify one of the `-Acdtrux' or `--test-label' options
Try `/usr/bin/tar --help' or `/usr/bin/tar --usage' for more information.

If I add quotes the error becomes:
c:\cygwin\bin\bash.exe -c '/usr/bin/tar tvf dld.gz'
tar (child): gzip: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
/usr/bin/tar: Child returned status 2
/usr/bin/tar: Error is not recoverable: exiting now


ANY help would be VERY appreciated!!!

I've never used Cygwin, but it looks like you need to add your Cygwin programs to your system PATH. The Setup.exe program can install various Cygwin components, I'd recommend Googling it.
