- z # Compression or decompression via gzip
- c # Create a new jar package
- v # Displays the tar command execution process
- f # Specify the file compression name
- t View the contents of the compressed package without decompressing it __________
- p # Keep the original attributes robust
- P
Exclude files or directories that do not need to be processed when packaging
- h # Packing Soft Connection File Pointing to
- j bzip2 command compression or decompression
- x # pressurized tar package
- C # Unzip to the specified directory
hard-derefrence # Packing Hard Link Files

. gzip
The gzip command can't compress directories directly, so it needs to pack a file with tar first, then tar calls gzip to compress.
- d # Add compressed files
- v Display the process of instruction execution
- l # List the content messages of the compressed file
- c
- r # Recursively compress all files in the directory
- t # test to check whether the compressed file is complete

. unzip
unzip commands can decompress zip-formatted files compressed by zip commands or other compression software
. scp
Copy files between different hosts, Using ssh protocol to ensure the security of replication, scp commands are replicated in full every time, inefficient
scp [options] [[user@]host1:]file1 ... [[user@]host2:]file2
- C
- l # Specifies the bandwidth occupied by the transmission
- P port # specified port number transmission
- p Retain the original properties of the file after transmission
- q) does not display the transmission progress bar
- r # Reproduce the entire directory recursively

. rsync
Excellent tools for full and incremental synchronous backup of local or remote data mirrors, suitable for multiple operating system platforms
It is a C/S mode service, managed by xinetd port.
rsync has three common modes:
1) Local mode Data transmission is similar to cp life, and av parameters are commonly used.
rsync [OPTION...] SRC... [DEST]
Source file, target file
2) daemon model#
Pull: rsync [OPTION...] [USER@]HOST::SRC... [DEST]
User@Host:: Source File, Object File
Push: rsync [OPTION...] SRC... [USER@]HOST::DEST
Source file User @Host:: Target file
3) Remote shell mode access # is similar to the scp command, except that user and host names need to be established.
Pull: rsync [OPTION...] [USER@]HOST:SRC... [DEST]
User@Host: Source File Object File
Push: rsync [OPTION...] SRC... [USER@]HOST:DEST
Source File User@Host: Target File
- v # Detailed Mode Output Progress Information
- z Compression during transmission to improve transmission efficiency
- a # Transfer files recursively and keep all file attributes
- r Transfer to subdirectories in recursive mode
- l # Retain Soft Connections
- n # Test Options, Simulated Execution
exclude=PATTERN # Specifies excluding file mode that does not need to be transferred
-- exclude-from=file # Reads the list of files to be excluded from the text file
- bwlimit=KBPS Restrict transmission speed
deldete Keep the contents of the target directory consistent with the source directory and delete different files
