I just attempted to use md5sum.exe under windows…

In a putty session on a Linux box I ran md5sum and then copied and pasted the output to a text file under windows…

[thejayster@abigbox thejayster]$ md5sum live-bak-200909250216AM.tar.gz
f7f3d5ac5cd898dbceaf1939c2228c15  live-bak-200909250216AM.tar.gz

# copy the output to windows

C:\backup>md5sum -c MD5SUM.txt

C:\backup>md5sum -c MD5SUM.txt

; this is after converting the MD5SUM.txt file to unix format using notepad++
