Compression is a technique to reduce the size of bunch of files stacked together. Archiving is a method to make single file of multiple files and folders.

It has 2 steps, Archiving & compression:

1. Archiving files in Linux:

An Archive is made using "tar"(Tape Archive Command).

Above command makes as an archive "example.tar" & puts all the files in current directory in it.

To list out the archived and compressed content without extracting as below,

2. Compressing files in Linux:

There are various tools to compress the file. They are follows:

Compress & Uncompress Tool:

[root@selva ~]# compress example.tar

Above command makes a compressed file  example.tar.Z in the current directory.

To uncompress the file use the following,

[root@selva ~]# uncompress example.tar.Z

Shortcut command to do compressing is,(Archiving + Compression)

[root@selva ~]# tar -Zcvf example.tar.Z

Shortcut Command to do the uncompressing is (Archiving + Uncompressing)

[root@selva ~]# tar -Zxvf example.tar.Z

GZIP & GUNZIP commands in Linux

[root@selva ~]# gzip example.tar

Above Command makes a compressed file example.tar.z in the current directory.

To Uncompress the file Gunzip tool is used..

[root@selva ~]# gunzip example.tar.z

Shortcut command to do the compressing is (Archiving + Compression )

[root@selva ~]# tar -zcvf example.tar.z

Shortcut command to do Uncomressing ( Archiving + Uncompression )

[root@selva ~]# tar -zxvf example.tar.z

BZIP2 & BUNZIP2 commands in Linux

To compress the file using bzip tool,

[root@selva ~]# bzip2 example.tar

Above command makes a compressed file example.tar.bz2 in the current directory.

To Uncompress the file bunzip2 tool is used,

[root@selva ~]# bunzip2 example.tar.bz2

Shortcut command to do the compressing ( Archiving + Compression )
