-t : displays or lists files in archived file
-u : archives and adds to an existing archive file
-v : Displays Verbose Information
-A : Concatenates the archive files
-z : zip, tells tar command that creates tar file using gzip
-j : filter archive tar file using tbzip
-W : Verify a archive file
-r : update or add file or directory in already existed .tar file
Usage
Creating an uncompressed tar Archive using option -cvf
This command creates a tar file called file.tar which is the Archive of all .c files in current directory.
tar -cvf <file-name>.tar *.c
Output:
os2.c
os3.c
os4.c
Extracting files from Archive using option -xvf
This command extracts files from Archives.
tar -xvf <file-name>.tar
Output:
os2.c
os3.c
os4.c
gzip compression on the tar Archive, using option -z
This command creates a tar file called file.tar.gz which is the Archive of .c files.
tar -cvzf <file-name>.tar.gz *.c
Extracting a gzip tar Archive *.tar.gz using option -xvzf
This command extracts files from tar archived file.tar.gz files.
tar -xvzf <file-name>.tar.gz
Creating compressed tar archive file in Linux using option -j
This command compresses and creates archive file less than the size of the gzip. Both compress and decompress takes more time then gzip.
tar -cvfj <file-name>.tar.tbz example.cpp
Output
$ tar -cvfj <file-name>.tar.tbz example.cpp
example.cpp
$ tar -tvf <file-name>.tar.tbz
-rwxrwxrwx root/root 94 2017-09-17 02:47 example.cpp
Untar single tar file or specified directory in Linux
This command will Untar a file in current directory or in a specified directory using -C option.
$ tar -xvfj file.tar
or
$ tar -xvfj file.tar -C <path-of-file-in-dir>
Untar multiple .tar, .tar.gz, .tar.tbz file in Linux
This command will extract or untar multiple files from the tar, tar.gz and tar.bz2 archive file. For example the above command will extract “fileA” “fileB” from the archive files.
$ tar -xvf <file-name>.tar "fileA" "fileB"
or
$ tar -zxvf <file-name>.tar.gz "fileA" "fileB"
or
$ tar -jxvf <file-name>.tar.tbz "fileA" "fileB"
Check size of existing tar, tar.gz, tar.tbz file in Linux
The above command will display the size of archive file in Kilobytes(KB).
$ tar -czf <file-name>.tar | wc -c
or
$ tar -czf <file-name1>.tar.gz | wc -c
or
$ tar -czf <file-name2>.tar.tbz | wc -c
Update existing tar file in Linux
tar -rvf <file-name>.tar *.c
Output:
os1.c
List the contents and specify the tarfile using option -tf
This command will list the entire list of archived file. We can also list for specific content in a tarfile
tar -tf <file-name>.tar
Output:
example.cpp
Applying pipe to through ‘grep command’ to find what we are looking for
This command will list only for the mentioned text or image in grep from archived file.
$ tar -tvf <file-name>.tar | grep "text to find"
or
$ tar -tvf <file-name>.tar | grep "filename.file extension"
We can pass a file name as an argument to search a tarfile
This command views the archived files along with their details.
Alternatively referred to as a ‘wild character’ or ‘wildcard character’, a wildcard is a symbol used to replace or represent one or more characters. Wildcards are typically either an asterisk (*), which represents one or more characters or question mark (?),which represents a single character.
To search for an image in .png format
This will extract only files with the extension .png from the archive file.tar. The –wildcards option tells tar to interpret wildcards in the name of the files to be extracted; the filename (.png) is enclosed in single-quotes to protect the wildcard () from being expanded incorrectly by the shell.
