Tar command syntax

To create a tar ball of /home/vivek/projects directory, run:
$ tar -cvf /home/vivek/projects.tar /home/vivek/projects

Combining find and tar commands

The syntax is:
find /dir/to/search/ -name "*.doc" -exec tar -rvf out.tar {} \;
OR
find /dir/to/search/ -name "*.doc" -exec tar -rvf out.tar {} +
For example:
find $HOME -name "*.doc" -exec tar -rvf /tmp/all-doc-files.tar "{}" \;
OR
find $HOME -name "*.doc" -exec tar -rvf /tmp/all-doc-files.tar "{}" +
Where, find command options:

• -name "*.doc" : Find file as per given pattern/criteria. In this case find all *.doc files in $HOME.
• -exec tar ... : Execute tar command on all files found by the find command.

Where, tar command options:

• -r : Append files to the end of an archive. Arguments have the same meaning as for -c option.
• -v : Verbose output.
• -f : out.tar : Append all files to out.tar file.

It is also possible to pipe output of the find command to the tar command as follows:
find $HOME -name "*.doc" -print0 | tar -cvf /tmp/file.tar --null -T -
The -print0 option passed to the find command deals with special file names. The –null and -T – option tells the tar command to read its input from stdin/pipe. It is also possible to use the xargs command:
find $HOME -type f -name "*.sh" | xargs tar cfvz /nfs/x230/my-shell-scripts.tgz
See the following man pages for more info:
$ man tar
$ man find
$ man xargs
$ man bash
