Description (partial)

Currently when performing a checksum on the NX-OS cli the output is not in a standard format and does not include the filename. This is problematic when performing a checksum on multiple files at once or using the output of the command as input for Unix or GNU/Linux `md5sum(1)` tools:
SWITCH(config)# show file n7700-s2-dk9.7.3.3.D1.1.bin md5sum

tac@desktop:$ md5sum n7700-s2-dk9.7.3.3.D1.1.bin
f90c20c1e27e7be052d332f5909c5f6f  n7700-s2-dk9.7.3.3.D1.1.bin
This is problematic when a wildcard is used on a list of files:
N77-C7706-1(config)# show file *.bin md5sum

All NX-OS based switches exhibit this behavior.
