Tar command format [-zjxcvfpP] filename tar

- z: Represents simultaneous gzip compression.

- j: Represents the simultaneous compression with bzip2.

- J: Represents the simultaneous compression with xz.

- x: Represents unpacking or decompression.

- t: To view the files in the tar package.

- c: Represents the creation of a tar package or a compressed file package.

- v: Representation visualization.

- f: Following the filename (that is - f filename), the compressed file is called filename, or the decompressed file is filename. In the case of multiple parameter combinations, please write the - f parameter to the end.)

- P: Represents properties that use the original file. (Not often used)

- p: Indicates that absolute paths can be used. (Not often used)

exclude filename: This means that when packaging or compressing, do not include filename files. (Not often used)

tar packaged file

[root@localhost test]# rm -f test111.tar
[root@localhost test]# tar -cf test.tar test111 1.txt
[root@localhost test]# ls

Packing and unpacking the original file will not be deleted

[root@localhost test]# rm -rf test111
[root@localhost test]# ls
1.txt  test.tar
[root@localhost test]# tar -xvf test.tar
test111/

1.txt

- exclude option: You can exclude files or delete files.

[root@localhost test]# tar -cvf test111.tar --exclude 1.txt test111
test111/
test111/2.txt

[root@localhost test]# mkdir test111/test222
[root@localhost test]# tar -cvf test111.tar --exclude test222  test111
test111/
test111/2.txt
test111/1.txt

zip command

zip commands compress directories and files, compress directories, need to specify the directory files.

[root@localhost test]# zip 1.txt.zip 1.txt
  adding: 1.txt (deflated 64%)
[root@localhost test]# zip test111.zip test111/*
  adding: test111/1.txt (deflated 64%)
  adding: test111/2.txt (stored 0%)
  adding: test111/test222/ (stored 0%)

Zip is followed by the target file name, the compressed custom compressed package name, and then by the file or directory to be compressed. Install zip directory command: Yum install-y zip

Zip-r: Compress files in the secondary directory together.

[root@localhost test]# zip -r test111.zip test111/
updating: test111/1.txt (deflated 64%)
updating: test111/2.txt (stored 0%)
updating: test111/test222/ (stored 0%)
  adding: test111/ (stored 0%)

Unzip: Unzip command. Install the unzip command: Yum install-y unzip.

[root@localhost test]# unzip 1.txt.zip
Archive:  1.txt.zip
replace 1.txt? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
  inflating: 1.txt                   
[root@localhost test]# yum install -y unzip

Packing and Compression

The tar command supports gzip compression, bzip2 compression, and xz compression.

Compressed into gzip format file

[root@localhost test]# tar -czvf test111.tar.gz test111
test111/
test111/2.txt
test111/1.txt
test111/test222/

With the - tf option, you can view a list of files for packages or compressed packages.

[root@localhost test]# tar -tf test111.tar.gz
test111/
test111/2.txt
test111/1.txt
test111/test222/
[root@localhost test]# tar -tf test.tar
test111/
test111/2.txt
test111/1.txt
1.txt

Using the - zxvf option, you can decompress the tar.gz format compression package.

[root@localhost test]# rm -rf test111
[root@localhost test]# ls
1.txt  1.txt.zip  test111.tar  test111.tar.gz  test111.zip  test.tar
[root@localhost test]# tar -zxvf test111.tar.gz
test111/
test111/2.txt
test111/1.txt
test111/test222/
[root@localhost test]# ls
1.txt  1.txt.zip  test111  test111.tar  test111.tar.gz  test111.zip  test.tar

Using bzip2 compression while packaging

Use the - cjvf option to compress:

[root@localhost test]# tar -cjvf test111.tar.bz2 test111
test111/
test111/2.txt
test111/1.txt
test111/test222/

Use the - tf option to view the list of compressed packages:

[root@localhost test]# tar -tf test111.tar.bz2
test111/
test111/2.txt
test111/1.txt
test111/test222/

Use - jxvf t:

[root@localhost test]# tar -jxvf test111.tar.bz2
test111/
test111/2.txt
test111/1.txt
test111/test222/
