1. Create an Archive
The syntax for creating an archive depends on the archive type. To make an archive, use tar with the -c or --create operation.
2. Remove Files After Creation
To remove the files from disk after archiving, use the --remove-files option at the end:
3. Extract from Archive
Extracting from an archive or compressed archive uses the -x or --extract operation with tar. The additional options depend on the file type and where tar should extract the components.
4. Overwrite Control
Tar overwrite controls handle situations where file names in the archive overlap with files in the working directory.
7. Find Multiple Files in an Archive
Use the --wildcards option to match multiple file instances. For example:
8. Exclude Files when Creating Archive
To exclude certain files from the archive during creation, add the following option:
10. Verbose Option
The verbose option displays additional information after running a tar command. Add -v or --verbose to any operation to see the result.
How does tar restore files?
Tar removes the prepending / in an Absolute Path. This means it will not automatically restore the files to their original location, but merely to their current location.

If tar is given a Relative Path, then you must extract the tar within the same directory you created the tar to restore the files to their original location.
Does tar compress data?
Tar has options for compressing data to varying degrees. Doing so can reduce the amount of space your archives take up. However, it can also take a heavy toll on system resources.

"Tar" and "pitch" can be used interchangeably; asphalt (naturally occurring pitch) may also be called either "mineral tar" or "mineral pitch". There is a tendency to use "tar" for more liquid substances and "pitch" for more solid (viscoelastic) substances. Both "tar" and "pitch" are applied to viscous forms of asphalt, such as the asphalt found in naturally occurring tar pits (e.g., the La Brea Tar Pits in Los Angeles). "Rangoon tar", also known as "Burmese oil" or "Burmese naphtha", is also a for…
