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 samplefile—a 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
"Initial Configuration,"
"Software Images,"

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

switch# gzip volatile:Samplefile

The gunzip command uncompresses (unzips) LZ77 coded files.
This example unzips the file that was compressed in the previous example:
switch# gunzip samplefile
