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 the file. The checksum values compute a cyclic redundancy check (CRC) for each named file. Use this command to verify that the files 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 2569913991 switch# show file bootflash://sup-1/ultimate_file.tar md5sum 52479aae2dce1fd849b6f4916d750392 Listing the Files in a Directory The dir command displays the contents of the current directory or the specified directory. The syntax for this command is dir directory or dir filename. This example shows how to list the files on the default volatile: file system. switch# dir Usage for volatile: filesystem 0 bytes total used 20971520 bytes free 20971520 bytes available Creating a Directory The mkdir command creates a directory at the current directory level or at a specified directory level. The syntax for this command is mkdir directory name. This example creates a directory called test in the slot0 directory: switch# mkdir slot0:test This example creates a directory called test at the current directory level: switch# mkdir test If the current directory is slot0:mydir, this command creates a directory called slot0:mydir/test. Deleting an Existing Directory The rmdir command deletes an existing directory at the current directory level or at a specified directory level. The directory must be empty to be deleted. The syntax for this command is rmdir directory name. This example deletes the directory called test in the slot0 directory: OL-18084-01, Cisco MDS NX-OS Release 4.x Cisco MDS 9000 Family CLI Configuration Guide 2-29
