Basic Usage[edit | edit source]
Create Archive[edit | edit source]
Use the -c option to create.

List Archive Contents[edit | edit source]
Use the -t option to list contents.

file1
file2
Extracting Files[edit | edit source]
To extract everything, use the -x.
$ tar -xf archive.tar
$ ls
file1
file2
To extract only a specific file or folder, pass the filename or path name after the archive.
$ tar -xf archive.tar file1
$ ls
file1
To extract based on a pattern:
$ tar -xf archive.tar --wildcards --no-anchored '*le1'
$ ls
file1

|
.tar.gz, .tgz |
