Solved: How do I Compress a Whole Linux or UNIX Directory?

How can I compress a whole directory under a Linux / UNIX using a shell prompt?

It is very easy to compress a Whole Linux/UNIX directory. It is useful to backup files, email all files, or even to send software you have created to friends. Technically, it is called as a compressed archive. GNU tar command is best for this work. It can be use on remote Linux or UNIX server. It does two things for you:

=> Create the archive

=> Compress the archive

You need to use the tar command as follows (syntax of tar command): tar -zcvf archive-name.tar.gz directory-name

Where,

-z : Compress archive using gzip program
-c: Create archive
-v: Verbose i.e display progress while creating archive
-f: Archive File name

For example, say you have a directory called /home/jerry/prog and you would like to compress this directory then you can type tar command as follows: $ tar -zcvf prog-1-jan-2005.tar.gz /home/jerry/prog

Above command will create an archive file called prog-1-jan-2005.tar.gz in current directory. If you wish to restore your archive then you need to use the following command (it will extract all files in current directory): $ tar -zxvf prog-1-jan-2005.tar.gz

Where,

-x: Extract files

If you wish to extract files in particular directory, for example in /tmp then you need to use the following command: $ tar -zxvf prog-1-jan-2005.tar.gz -C /tmp $ cd /tmp $ ls - A note about non gnu/tar command

The above syntax use GNU tar command for compressing and uncompressing tar files. If your system does not use GNU tar, you can still create a compressed tar file, via the following syntax: tar -cvf - file1 file2 dir3 | gzip > archive.tar.gz See also:
