How to create a tar file in linux

create a tar file in linux systems

create a tar for all available file in directories
tar -cvf out_test.tar.z *

create a tar for specific file extension
tar -cvf out1_test.tar.z *.log

create a tar for multiple directory
tar -cvf out1_tar.z /home/oradev/out1 /home/oradev/out2

create compress tar file .gz(it will compress the file size)

tar -cvzf compress.tar.gz *.log

[oradev@erp2 out1]$ ls -lt
-rw-rw-r-- 1 oradev oradev   145 Dec  6 16:12 compress.tar.gz
-rw-rw-r-- 1 oradev oradev 10240 Dec  6 16:00 out1_test.tar.z
-rw-rw-r-- 1 oradev oradev 10240 Dec  6 15:58 out_test.tar.z

Another compress options available it slow  compare previous one

tar cvfj compress3.tar.bz2 *.log

Untar commands:

Untar the files to current directory

tar -xvf out1_tar.z

tar -xvf compress.tar.gz

tar -xvf compress2.tar.bz2

Untar the files to remote directory

tar -xvf out_test.tar.z -C /home/oradev/out2/

tar -xvf compress.tar.gz -C /home/oradev/out2/

tar -xvf compress2.tar.bz2 -C /home/oradev/out2/

Untar specific file from tar file:

tar -xvf out1_tar.z test1.log

tar -zxvf compress.tar.gz test1.log

tar -jxvf compress2.tar.bz2  /home/oradev/test1.log

Untar multiple files from tar file.

tar -xvf out2.tar.z best1.log best2.log

tar -zxvf out2.tar.z best1.log best2.log

tar -jxvf out2.tar.z best1.log best2.log

Untar group of files :

tar -xvf out2.tar.z --wildcards  '*.log'

tar -zxvf out2.tar.z --wildcards  '*.log'

tar -jxvf out2.tar.z --wildcards  '*.log'

Include the file or directories into the tar file:

tar -rvf out_tar.z out2

tar -rvf out_tar.z best1.log

Note : Its not possible for compress tar gz and bz2

To count the tar file size:

tar -czf - out23_tar.z |wc -l

tar -czf - out23_tar.gz |wc -l

tar -czf - out23_tar.bz2 |wc -l

Exclude the file from directory while create tar file.

tar -cvzf out23_tar.gz /home/oradev/test --exclude=/home/oradev/old --exclude=/home/oradev/best

tar -cvf out23_tar.z /home/oradev/test --exclude=/home/oradev/old --exclude=/home/oradev/best

tar -cvfj out23_tar.gz /home/oradev/test --exclude=/home/oradev/old --exclude=/home/oradev/best


List of available files in created tar file:

tar -tvf out1_tar.z

tar -tvf  compress.tar.gz

tar -tvf compress.tar.gz
