This example changes the current directory to the mystorage directory that resides in the current

Displaying File Checksums
The show file file md5sum command provides the MD5 checksum of file. MD5 is an electronic
fingerprint for the file. MD5 is the latest implementation of the internet standards described in RFC 1321
and is useful for data security as well as integrity.
The show file file cksum command provides the checksum of file. The checksum values compute a
cyclic redundancy check (CRC) for each named file. Use this command to verify that are not
corrupted—compare the checksum output for the received file against the checksum output for the
original file.
This example provides the output of the show file command when a file is specified.
switch# show file bootflash://sup-1/ultimate_file.tar cksum
