Using the latest (as of 2001/06/05) update of Cygwin, running 'md5sum -c md5.sum' produces mostly failed checksums when checking against binary files. However, when running 'md5sum *', the checksums produced are identical to those in the md5.sum file except that each file has an asterisk '*' prepended to it. When the md5.sum file is editted to add an asterisk before each filename, 'md5sum -c md5.sum' produces all 'OK' results. This looks to be an error when md5sum is checking (-c option) binary files. This occurs irregardless of whether or not the CYGWIN environment variable is set in cygwin.bat to binmode. Note: the '-b' option cannot be used with the '-c' option. My specific test case was with the Cygwin-XFree86 files for download. There is an md5.sum file there which works fine when I run a Perl based MD5 checker. And like I said, you can add an '*' before each file in that md5.sum and then the cygwin 'md5sum -c md5.sum' command works fine. ftp://ftp.sunsite.utk.edu/pub/cygwin/xfree/xc-4-binaries/4.1.0/ -- Mike Arms [EMAIL PROTECTED] -- Want to unsubscribe from this list?
