初探Linux gz压缩命令（gz压缩命令linux）

GNU’s gzip is a file compression tool used in the Linux operating system. It is a data compression algorithm that is used for compressing a set of files into a single file, often referred to as an archive. A .gz extension is used to indicate a file that is compressed with gzip. This extension is typically appended to the name of the original input file to give it a new name.

To begin working with gz files on Linux, it is important to understand how to use the command line tools available to compress and decompress files. For that, we will use the gzip utility.

The gzip utility is used to read, write, compress and decompress files. It can also be used to list the contents of a compressed file and check the size of a file before and after compression.

To compress a file using the gzip utility, you can use the following command:

gzip -c >

Here is the file you want to compress and is the name of the resulting compressed file.

Similarly, to decompress a gz file, you can use the following command:

gunzip

Here filename.gz is the name of the gz file you want to decompress.

You can also use the tar command to compress multiple files into a tar.gz archive. To compress multiple files and directories into a tar.gz archive, you can use the following command:

tar -zcvf

Here archive-name.tar.gz is the name of the resulting tar.gz archive, and files-directory is the name of the directory containing the files you want to compress.

In addition to compressing and decompressing files, the gzip utility allows you to set the compression level. To set the compression level, you can use the -l option with the gzip command.

For example, to set the compression level to the highest level (level 9), you can use the following command:

gzip -c -9 >

Finally, you can use the -t option with the gzip command to test a .gz file for correctness. To test a .gz file, you can use the following command:

gunzip -t

Here filename.gz is the name of the gz file you want to test.

The command line gzip tool is a handy and powerful tool that can be used to compress and decompress files in the Linux operating system. It can also be used to set the compression level, list the contents of a compressed file and check the file size before and after compression.
