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
Building Configuration ...
switch# dir
1525859 Jul 04 00:51:03 2003 Samplefile
Usage for volatile://
1527808 bytes used
19443712 bytes free
20971520 bytes total
switch# gzip volatile:Samplefile
switch# dir
266069 Jul 04 00:51:03 2003 Samplefile.gz
Usage for volatile://
266240 bytes used
20705280 bytes free
20971520 bytes total
The gunzip command uncompresses (unzips) LZ77 coded files.
This example unzips the file that was compressed in the previous example:
switch# gunzip Samplefile
switch# dir
1525859 Jul 04 00:51:03 2003 Samplefile
Usage for volatile://
1527808 bytes used
19443712 bytes free
20971520 bytes total
