tapefs

TAPEFS(1)						      General Commands Manual							 TAPEFS(1)

NAME

       32vfs, cpiofs, tapfs, tarfs, tpfs, v6fs, v10fs - mount archival file systems

SYNOPSIS

       fs/32vfs [ -m mountpoint ] [ -p passwd ] [ -g group ] file
       fs/cpiofs
       fs/tapfs
       fs/tarfs
       fs/tpfs
       fs/v6fs
       fs/v10fs

DESCRIPTION

       These commands interpret data from traditional tape or file system formats stored in file, and mount their contents (read-only) into a Plan
       9 file system.  The optional -p and -g flags specify Unix-format password (respectively group) files that  give	the  mapping  between  the
       numeric	user-  and  group-ID numbers on the media and the strings reported by Plan 9 status inquiries.	The -m flag introduces the name at
       which the new file system should be attached; the default is /n/tapefs.

       32vfs interprets raw disk images of 32V systems, which are ca. 1978 research Unix systems for the VAX, and also pre-FFS Berkeley  VAX  sys-
       tems (1KB block size).

       Cpiofs interprets cpio tape images (constructed with cpio's c flag).

       Tarfs interprets tar tape images.

       Tpfs interprets tp tapes from the Fifth through Seventh Edition research Unix systems.

       Tapfs interprets tap tapes from the pre-Fifth Edition era.

       V6fs interprets disk images from the Fifth and Sixth edition research Unix systems (512B block size).

       V10fs interprets disk images from the Tenth Edition research Unix systems (4KB block size).

SOURCE

       These  commands	are  constructed  in a highly stereotyped way using the files fs.c and util.c in /sys/src/cmd/tapefs, which in turn derive
       substantially from ramfs(4).
