How to decompress files in linux

1. zip format

zip may be the most commonly used document compression format. Its biggest advantage is that it can be used on different operating system platforms. The disadvantage is that the compression rate supported is not very high, and tar.gz and tar.bz2 do a very good job in terms of compression rate.

We can use the following command to compress a file:

zip -r archive_name.zip filename    （-r是压缩文件）

The following is how to decompress a zip file:

unzip archive_name.zip              （解压文件在当前文件下）
unzip archive_name.zip -d new_dir   （解压文件可以将文件解压缩至一个你指定的的目录，使用-d参数）

2. tar format

tar is a document packaging format that is widely used in Linux. Its advantage is that it only consumes very little CPU and time to package files. It is just a packaging tool and is not responsible for compression. Here's how to package a directory:

tar -cvf archive_name.tar directory_to_compress

-c parameter is to create a new archive

-v parameter displays the processed files in detail

-f parameter specifies the archive or device

How to unpack after packaging:

tar -xvf archive_name.tar

The above unpacking command will unpack the document in the current directory. Of course, you can also use the following command to unpack to the specified path:

tar -xvf archive_name.tar -C new_dir

The unpacking parameter is -C, not lowercase c

3. tar .gz format

This format is the compression format I use most. It does not take up too much CPU when compressing, and can get a very ideal compression rate.

Compression method:

tar -zcvf archive_name.tar.gz filename

Decompression method:

tar -zxvf archive_name.tar.gz

The above unpacking command will unpack the document in the current directory. Of course, you can also use the following command to specify the unpacking path:

tar -zxvf archive_name.tar.gz -C new_dir

4. tar.bz2 format

This compression format is The best compression of all the methods we mentioned. Of course, this means that it takes up more CPU and time than the previous method.

Compression method:

tar -jcvf archive_name.tar.bz2 filename

Decompression method:

tar -jxvf archive_name.tar.bz2

The above unpacking command will unpack the document in the current directory. Of course, you can also use the following command to specify the unpacking path:

tar -jxvf archive_name.tar.bz2 -C new_dir
