NAME
       efsextract - extract files from SGI CD images or EFS file systems

SYNOPSIS
       efsextract [OPTION] [FILE]
       efsextract [-h|-V]

DESCRIPTION
       efsextract extracts files from an SGI CD image, or an EFS file
       system.

       Silicon Graphics (SGI) was a computer company that existed from 1981
       to 2009. During this period, they shipped software for their
       computers, sometimes on CD, and often not using the standard ISO9660
       file system.  These discs are instead simply hard disc images pressed
       to CD. Thus, they have an SGI disk label and an EFS partition.

       Most systems cannot understand this sort of disc format. This tool
       was developed to allow non-SGI systems to at least be able to extract
       files from such discs.

OPTIONS
       -f     Delete destination files if they already exist.

       -h     Print a usage message on standard output and exit
	      successfully.

       -l     List files without extracting.

       -L     List partitions and bootfiles from the volume header.

       -o ARCHIVE
	      Instead of extracting, create a tar archive ARCHIVE containing
	      all files from the image.

       -p NUM Use partition number NUM (default: 7).

       -q     Do not show file listing while extracting.

       -V     Print version information on standard output and exit
	      successfully.

       -W     Instead of extracting, scan the image for `inst' packages and
	      list them.

       -X     Extract bootfiles from the volume header.
