8.5. Archiving File Systems With ACLs


The tar and dump commands do not backup ACLs.

The star utility is similar to the tar utility in that it can be used to generate archives of files; however, some of its options are different. Refer to Table 8.1, “Command Line Options for star” for a listing of more commonly used options. For all available options, refer to the star man page. The star package is required to use this utility.

Option Description
-c Creates an archive file.
-n Do not extract the files; use in conjunction with -x to show what extracting the files does.
-r Replaces files in the archive. The files are written to the end of the archive file, replacing any files with the same path and file name.
-t Displays the contents of the archive file.
-u Updates the archive file. The files are written to the end of the archive if they do not exist in the archive or if the files are newer than the files of the same name in the archive. This option only work if the archive is a file or an unblocked tape that may backspace.
-x Extracts the files from the archive. If used with -U and a file in the archive is older than the corresponding file on the file system, the file is not extracted.
-help Displays the most important options.
-xhelp Displays the least important options.
-/ Do not strip leading slashes from file names when extracting the files from an archive. By default, they are striped when files are extracted.
-acl When creating or extracting, archive or restore any ACLs associated with the files and directories.
