NAME

       viewsudo - execute a command as another (virtual) user

SYNOPSIS

       viewsudo [-g groupname|#gid] [-u username|#uid] command

DESCRIPTION

       viewsudo allows a user to execute a command as the superuser or
	      another user in View-OS.

OPTIONS

       viewsudo accepts the following command line options:

       -g group
	   Normally,  viewsudo	sets the primary group to root.  The -g option causes sudo to run the specified command with the primary group set
	   to group.  To specify a gid instead of a group name, use #gid.  When running commands as a gid, many shells require	that  the  '#'	be
	   escaped  with  a  backslash	('[u2019]).   If  no -u option is specified, the command will be run as the invoking user (not root).	In
	   either case, the primary group will be set to group.

       -u user
	   The -u option causes viewsudo to run the specified command as a user other than root.  To specify a uid instead of  a  user	name,  use
	   #uid.  When running commands as a uid, many shells require that the '#' be escaped with a backslash ('[u2019]).

RETURN VALUES

       Upon successful execution of a program, the exit status from viewsudo will simply be the exit status of the program that was executed.

NAME

       umfuse - User Mode FUSE implementation for umview

SYNOPSIS

       um_add_service umfuse.so
       umview ... --preload umfuse.so

DESCRIPTION

       umfuse  is the user-mode implementation of virtual FUSE filesystems for umfuse.	When this service module is loaded it is possible to mount
       umfuse file systems.  FUSE and umfuse are source level compatible, it is possible to compile a FUSE file system implementation as a dynamic
       library.  The name of umfuse file system implementation libraries must begin with umfuse.

       Umfuse implemented file system are mounted and umounted by the standard utilities mount(8) and umount(8).

       Example:
	    $ mount -t umfuseext2 /path/to/file.img /mount/point
	    ...
	    $ umount /mount/point
       The mount command for umfuse file systems allows some specific options:

       debug
	   give a verbose feedback of each operation on the virtual file system.

       fuseuid=uid
	   specify the effective uid for the operation on the virtual file system

       fusegid=gid
	   specify the effective gid for the operation on the virtual file system

       human
	   umfuse  is  default mode is omnipotent, i.e. the user acts as root in the mounted file system. When a file system gets mounted with the
	   human option, access control is enforced.

       umfuse modules main program invocation options.
       umfuse calls the main program of the module with the standard syntax:
	     umfusexxxx -o options source mountpoint
       Sometimes FUSE modules have been designed to accept a different syntax.	It is possible to match the calling syntax by using  the  follwing
       options.

       nosource
	   No image file should be specified.

       pre=string
	   The string contains parameters that must be put before "-o options"

       post=string
	   The string contains parameters that must be added at the end

       format=string
	   This  is  the most powerful rewriting rule. If the main needs a completely different structure format can be used: the format string is
	   similar to that used in printf.  %O %S %M descriptors are substituted in the call as follows: %O=-o options, %S=source, %M=mountpoint.

       showcall
	   Show the call syntax before the actual call.  Use it for debugging.
