11.G.ii. GUNZIP the Compressed Data from the Web Site
Any data with a .gz extension must be uncompressed with GUNZIP. The command syntax may be one of these:
gunzip inputfilename gzip -d inputfilename
This will uncompress the data, remove the .gz file extension, and delete the compressed .gz file. Note that you must have enough hard disk space to uncompress a file. Compressed and uncompressed file sizes are given in Table 3 (Section 11.C). lf you are not familiar with GUNZIP, go to http://www.gzip.org.
