Using Switch File Systems Chapter 2 Before You Begin Send documentation comments to [email protected] switch# delete dns_config.cfg This example shows how to delete a file from an external CompactFlash (slot0): switch# delete slot0:dns_config.cfg This example deletes the entire my-dir directory and all its contents: switch# delete bootflash:my-dir Caution If you specify a directory, the delete command deletes the entire directory and all its contents. Displaying File Contents The show file command displays the contents of a specified file in the file system. The syntax for this command is show file filename. This example displays the contents of the test file that resides in the slot0 directory: switch# show file slot0:test config t Int fc1/1 no shut end show int fc1/1 This example displays the contents of a file residing in the current directory: switch# show file myfile Saving Command Output to a File You can force all screen output to go to a file by appending > filename to any command. For example, enter show interface > samplefile at the EXEC mode switch prompt to save the interface configuration to a samplefile file created at the same directory level. At the EXEC mode switch prompt, issue a dir command to view all files in this directory, including the recently saved samplefile. See Chapter 5, "Initial Configuration," for information on saving and copying configuration files, and Chapter 8, "Software Images," for information on saving and copying software images. Note As of MDS NX-OS Release 4.1(1a), redirection is allowed regardless of the current directory. In the earlier releases, redirection is allowed only if the current directory is on the volatile: (default) or slot0: file systems, and redirection is not allowed if the current directory is on the bootflash: file system. The current directory can be viewed using the pwd command and changed using the cd command. Compressing and Uncompressing Files The gzip command compresses (zips) the specified file using LZ77 coding. This example directs the output of the show tech-support command to a file (Samplefile) and then zips the file and displays the difference in the space used up in the volatile: directory: switch# show tech-support > Samplefile 2-32 Cisco MDS 9000 Family CLI Configuration Guide OL-18084-01, Cisco MDS NX-OS Release 4.x
