linux unzip an Affymetrix annotation file

[jhan]

Hi,
I am new to this forum and new to bioinformatics. I am stuck in a simple question here.
I have this annotation file, .csv.zip downloaded from the Affymetrix website. In Linux, I used gunzip first followed by the filename. Error says wrong suffix. Then I changed .zip to .gz, it says the file contains more than one entry.
Anyone can help?

zip is not gzip.
unzip is not gunzip
Similar ideas but different programs using different algorithms.
Use unzip for zip files.
Use gzip for gz files.

It works. Thanks Richard for answering my first question in the forum.
