1. gzip compression and decompression
Because they are all included in the system, we don't need to install them;
ls Look at the current files in the directory and create a touch 123.txt file;
gzip for compression, ("gzip 123.txt"), so the compression is complete;
The original file has disappeared, and the generated file is 123.txt.gz;
gzip to decompress, ("gzip -d 123.txt.gz"), so that the decompression is complete;
2. bzip2 compression and decompression
Because they are all included in the system, we don't need to install them;
bzip2 for compression, (" bzip2 -k 123.txt "), so that the compression is complete;
The original file is kept, and the generated file is 123.txt.bz2;
bzip2 to decompress, ("bzip2 -k -d 123.txt.bz2"), so the decompression is complete;
3. rar compression and decompression
First you need to install it, ("sudo apt install rar"), verify the password to install;
You also need to install the decompression tool, ("sudo apt intsall unrar");
rar for compression, ("rar a 123.rar"), so the compression is complete;
Unrar to decompress, ("unrar e 123.rar"), so that the decompression is complete;
tar archive compression and decompression package
The tar command can pack one or more files and folders into one file;
The file can be in tar format with a .tar extension: ("tar -cvf test.tar test1 test2 test3");
To extract a tar file, you can use the following command: ("tar -xvf test.tar");
tar compression format, with .tar.gz or .tgz extension: ("tar -cvf test.tar.gz test1 test2 test3");
To uncompress a tar.gz file, you can use the following command: ("tar -xvf test.tar.gz");
