tar [-cxtzjvfpPN] files and directories....
parameter:
-c : parameter command to create a compressed file (meaning of create);
-x : Unpack the parameter command of a compressed file!
-t : View the files in the tarfile!
Special attention, in the parameter assignment, only one c/x/t can exist! cannot exist at the same time!
Because it is impossible to compress and decompress at the same time.
-z : Does it also have the gzip attribute? That is, does it need to be compressed with gzip?
-j : Does it also have the properties of bzip2? That is, does it need to be compressed with bzip2?
-v : Display files during compression! This is commonly used, but it is not recommended to be used in the background execution process!
-f : Use the file name, please pay attention to the file name immediately after f! Do not add parameters!
x is decompression
c is compression
z refers to gz files.
j refers to bz file
f specifies the file
================
Unzip: tar jxvf FileName.tar.bz2
Compression: tar jcvf FileName.tar.bz2
z is used to decompress .tar.gz files, and .tar.bz2 files have to be replaced with j, like this:
tar -xjvf linux-2.6.20.tar.bz2
Take a look at the parameter description:
x: decompress
j：bz2
f: specified file

describe
The tar program is used to store or expand tar archive files. Archive files can be placed on disk or stored as regular files. tar requires parameters. The optional parameters are A, c, d, r, t, u, x. When using tar, you must first specify at least one parameter for tar; then, you must specify the file or directory to be processed . If a directory is specified, all subdirectories under that directory will be added to the archive.
Application examples:
1) Expand abc.tar.gz Use the command: tar xvzf abc.tar.gz Expand abc.tar Use the command: tar xvf abc.tar
2) Save the man directory and its subdirectories in the current directory as an archive man.tar tar cf man.tar ./man
Parameter Description
When running tar, you must have at least one of the following parameters to run
-A, --catenate, --concatenate
Merge an archive with an existing archive
-c, --create
create new archive
-d, --diff, --compare
Compare the difference between the archive and the current file
--delete
delete from archive
-r, --append
Append to end of archive
-t, --list
List directories of files in archive
-u, --update
Append only newer files to the archive
-x, --extract, --get
Expand file from archive
Other parameters
--atime-preserve
Do not change the access time of the dump file
-b, --block-size N
Specify a block size of Nx512 bytes (N=20 by default)
-B, --read-full-blocks

-C, --directory DIR
Go to the specified directory
--checkpoint

-h, --dereference
Do not dump dynamic links, dump the files pointed to by dynamic links.
