How to make user groups and edit permissions?

OK guys and gals.

I've been working on a debian system for a little bit, in hopes of making it into a system we can use for manifests and other things.

I am very new to unix, particularly debian.

I would like to make 2 or 3 different groups.

1 would be for me, and other people administrating. I figured I could either use root or the normal user for this.

The 2nd would be for people who needed to update the manifest. IE, If they took out 300 sand bags, they would need to be able to input that they had took out 300. This needs to link to my PC upstairs, and display the amounts of each item left, how many are currently out, who took them out, when they are expected back in, and where they are going.

The 3rd would be for people who were going to need to access the system remotely. I was thinking of using VMware?

Before I make the program for the manifests, I need to make the groups.

1 for me, 1 for people inputting data and 1 for people who are more experienced than me so that they can use VMware to remotely connect and do things like witchcraft and magic, and other bits.

I was looking for what people recommend they should have access to, and how to edit their permissions. IE, should people down stairs just have access to my program or what?

I may post more things later, as the machine is built Smilie

Any help appreciated.

dlarrj

dlarrj.f(3)							      LAPACK							       dlarrj.f(3)

NAME

       dlarrj.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlarrj (N, D, E2, IFIRST, ILAST, RTOL, OFFSET, W, WERR, WORK, IWORK, PIVMIN, SPDIAM, INFO)
	   DLARRJ

Function/Subroutine Documentation
   subroutine dlarrj (integerN, double precision, dimension( * )D, double precision, dimension( * )E2, integerIFIRST, integerILAST, double
       precisionRTOL, integerOFFSET, double precision, dimension( * )W, double precision, dimension( * )WERR, double precision, dimension( *
       )WORK, integer, dimension( * )IWORK, double precisionPIVMIN, double precisionSPDIAM, integerINFO)
       DLARRJ

       Purpose:

	    Given the initial eigenvalue approximations of T, DLARRJ
	    does  bisection to refine the eigenvalues of T,
	    W( IFIRST-OFFSET ) through W( ILAST-OFFSET ), to more accuracy. Initial
	    guesses for these eigenvalues are input in W, the corresponding estimate
	    of the error in these guesses in WERR. During bisection, intervals
	    [left, right] are maintained by storing their mid-points and
	    semi-widths in the arrays W and WERR respectively.

       Parameters:
	   N

		     N is INTEGER
		     The order of the matrix.

	   D

		     D is DOUBLE PRECISION array, dimension (N)
		     The N diagonal elements of T.

	   E2

		     E2 is DOUBLE PRECISION array, dimension (N-1)
		     The Squares of the (N-1) subdiagonal elements of T.

	   IFIRST

		     IFIRST is INTEGER
		     The index of the first eigenvalue to be computed.

	   ILAST

		     ILAST is INTEGER
		     The index of the last eigenvalue to be computed.

	   RTOL

		     RTOL is DOUBLE PRECISION
		     Tolerance for the convergence of the bisection intervals.
		     An interval [LEFT,RIGHT] has converged if
		     RIGHT-LEFT.LT.RTOL*MAX(|LEFT|,|RIGHT|).

	   OFFSET

		     OFFSET is INTEGER
		     Offset for the arrays W and WERR, i.e., the IFIRST-OFFSET
		     through ILAST-OFFSET elements of these arrays are to be used.

	   W

		     W is DOUBLE PRECISION array, dimension (N)
		     On input, W( IFIRST-OFFSET ) through W( ILAST-OFFSET ) are
		     estimates of the eigenvalues of L D L^T indexed IFIRST through
		     ILAST.
		     On output, these estimates are refined.

	   WERR

		     WERR is DOUBLE PRECISION array, dimension (N)
		     On input, WERR( IFIRST-OFFSET ) through WERR( ILAST-OFFSET ) are
		     the errors in the estimates of the corresponding elements in W.
		     On output, these errors are refined.

	   WORK

		     WORK is DOUBLE PRECISION array, dimension (2*N)
		     Workspace.

	   IWORK

		     IWORK is INTEGER array, dimension (2*N)
		     Workspace.

	   PIVMIN

		     PIVMIN is DOUBLE PRECISION
		     The minimum pivot in the Sturm sequence for T.

	   SPDIAM

		     SPDIAM is DOUBLE PRECISION
		     The spectral diameter of T.

	   INFO

		     INFO is INTEGER
		     Error flag.
