So reading as text is the default where it doesn't matters? This leave us with the bad thing that a ' ' md5sum calculated on POSIX systems makes the Windows user think he should validate the file using --text which would fail. Or in other words you can never validate a ' ' md5sum unless you know about the platform which calculated it. BTW Hm, even I've tried on Windows cmd, mingw, cygwin ... I could not find any case where the calculated md5sum differs when using --text or --binary. It's always --binary like. Is that mingw/cygwin magic? See for example this text file with and without CRLF line feed, on Posix system: rudi@plutos:~/tmp> md5sum < text_lf 3290ec3c19a8a39362f7d70043f15627 - rudi@plutos:~/tmp> md5sum < text_crlf e452464ee760e85acf275f207a520147 - rudi@plutos:~/tmp> tr -d '\r' < text_crlf |md5sum 3290ec3c19a8a39362f7d70043f15627 - mingw binary used in Windows cmd: C:\MinGW\msys\1.0\bin>md5sum.exe Y:rudi\tmp\text_crlf \e452464ee760e85acf275f207a520147 *Y:rudi\\tmp\\text_crlf C:\MinGW\msys\1.0\bin>md5sum.exe --text Y:rudi\tmp\text_crlf \e452464ee760e85acf275f207a520147 Y:rudi\\tmp\\text_crlf C:\MinGW\msys\1.0\bin>md5sum.exe --binary Y:rudi\tmp\text_crlf \e452464ee760e85acf275f207a520147 *Y:rudi\\tmp\\text_crlf C:\MinGW\msys\1.0\bin>md5sum.exe Y:rudi\tmp\text_lf \3290ec3c19a8a39362f7d70043f15627 *Y:rudi\\tmp\\text_lf C:\MinGW\msys\1.0\bin>md5sum.exe --text Y:rudi\tmp\text_lf \3290ec3c19a8a39362f7d70043f15627 Y:rudi\\tmp\\text_lf C:\MinGW\msys\1.0\bin>md5sum.exe --binary Y:rudi\tmp\text_lf \3290ec3c19a8a39362f7d70043f15627 *Y:rudi\\tmp\\text_lf cu, Rudi
