To access gzipped files, you'll need to unzip them. You do so using gunzip, as Code Listing 13.11 shows.
To unzip a gzip file with gunzip:
1. | |
2. | gunzip zipadeedoodah.tar Enter gunzip and the name of the file to unzip. gunzip will uncompress the file(s) and return you to the shell prompt. |
Tip
When you're unzipping files with gunzip, you're not required to enter the file extension. gunzip zipadeedoodah would work just as well as gunzip zipadeedoo dah.tar.
Tip
Some systems don't recognize the gunzip command, so you might need to use gzip -d to uncompress the files.
Tip
If you have a compressed file that you know is text— oldfunnysayingsfromthenet.gz, for example—you can uncompress it (without deleting the original file) and view it with a single command: zcat oldfunnysayingsfromthenet | more.
Tip
gunzip understands how to uncompress most (compressed) files, including those compressed with compress or zip files from DOS/Windows systems.
