Eh??? Standard cmd.exe, or even the older command.com, should be well able handle such a pipe, provided the programs can be found in the PATH. Clarke mentioned that he was using Cygwin, which most *definitely* can, as can the MSYS shell which I use. Of course, `cat' isn't a standard Windows command, (although both Cygwin and MSYS provide it); however, you can just as well say: jpegtopnm < foo.jpeg | pnmtops > foo.eps > I'm quite sure that there are precompiled binaries of netpbm for > your favourite platform available in the internet. Since netpbm > tools are working on the command line, no GUI issues can arise. There may well be a Cygwin specific build available -- I don't know. I use the GnuWin32 distribution from: http://sourceforge.net/project/showfiles.php?group_id=23617&package_id=16357 This is a *native* Win32 port, which should work from *any* shell running on Win32.
