In linux, what is tar

 In linux; tar  (Tape ARchive) is file format and name of a program used to simply combine a few files into a single file, for easy storage and distribution. (.zip and .rar in window)
              In computing tar (derived from tape archive) is both a file format and the name of a program used to handle such files.
  • *.tar
  • *.tgz is equivalent to *.tar.gz (gzip)
  • *.tbz and *.tb2 are equivalent to* .tar.bz2 (bzip)
  • *.taz is equivalent to *.tar.Z
  • *.tlz is equivalent to *.tar.lz
  • *.txz is equivalent to *.tar.xz
A tar file or compressed tar file is commonly referred to as a tarball
Note: A ".tar" file is not a compressed files, it is a collection of files within a single file uncompressed. If the file is a .tar.gz ("tarball") or ".tgz" file it is a collection of files that is compressed. If you are looking to compress a file you would create the tar file then gzip the file.

1. Creating an archive using tar command :
1.1    Creating a tar file:
             $ tar cvf archive_name.tar dirname/
  • The letter c means "create archive".
  • The letter v means "verbose", which tells tar to print all the filenames as they are added to the archive.
  • The letter f tells tar that the name of the archive appears next (right after these options).
1.2    Creating a tarred file that is compressed with gzip
            $ tar cjzf archive_name.tgz dirname/
                 'z' means "compress this archive with gzip

1.3    Creating a tarred file that is compressed with bzip
            $ tar cvjf archive_name.tbz dirname/
                   'j' means "compress this archive with bzip


2. Extracting (untar) an archive using tar command
2.1    Extract a *.tar archieve
            $ tar xvf archieve_name.tar
                   x – extract files from archive

2.2    Extract a gzipped tar archive ( *.tgz )
           $ tar xvzf archieve_name.tgz

2.3    Extracting a bzipped tar archive ( *.tbz ) 

           $ tar xvjf archieve_name.tbz


3. Listing an archive using tar command
3.1   View the tar archive file
$ tar tvf archive_name.tar

 

3.2   Extract a gzipped tar archive ( *.tgz )

          $ tar tvzf archieve_name.tgz

3.3   Extracting a bzipped tar archive ( *.tbz )

          $ tar tvjf archieve_name.tbz

Philosophy of programmer


Just remember that this is your journey, not theirs. Being different is not a crime, and people who tell you it is are just jealous that you have picked up a skill they never in their wildest dreams could acquire.

You can code. They cannot. That is pretty damn cool.
It seems stupidly obvious, but, if you have a problem typing, you will have a problem learning to code Remember that anything worth doing is difficult at first...
Maybe you never learned self-discipline so you can't do anything that's "boring".

Crypt4Free
                Crypt4Free is a small package that allows easy encryption and schredding (secure deletion) of
files on your Windows system. It also compresses encrypted files to reduce size while sending. Get it from click here


MyPadlock
                 MyPadlock locks down all your passwords using 128-bit AES encryption — all you need to remember is one master password in order to access all the passwords you have stored inside. Data is stored locally. Get it from click here


Zero Footprint Crypt
                  Equally suited to both beginners and experts, Zero Footprint Crypt works just like a file explorer
(with the same tree-style/hierarchy structure). After encryption, you can also use it to securely wipe the original file from the drive.
