PsiFS: *Commands

*PsiFSTar

`*PsiFSTar`
	Read the contents of a tar file

Syntax:	`*PsiFSTar tar_file [object_spec [directory]] [-list]`

Parameters:	`tar_file`	a valid pathname specifying a `tar` file
	`object_spec`	a wildcard specification for matching against
	`directory`	a valid pathname specifying a directory
	`-list`	list matching objects only

Use:	`PsiFSTar` reads the contents of a `tar` file. All of the variants supported by SparkFS* are handled, including `arctar`, `comma`, `fltar` and `unix`. However, this command is intended solely to allow restoration of backup files produced by *PsiFS. The default pattern is ``, which will match all objects within the source file. The current directory can be specified by `@`. The `-list` switch suppresses extraction of the files, giving the effect of just listing the files contained within the source file.

Example:	`*PsiFSTar Backup -list`	List all files in `Backup`
	`PsiFSTar Backup /txt PsiFS::Internal.$`	Restore all files with a `txt` extension to their original directories
