Hi all

Hi friends,
I have a some files in a directory. for example
856-abc
856-def
851-abc
945-def
956-abc
852-abc
i want to display only those files whose name starts with 856* 945* and 851* using a single pattern.
i.e
856-abc
856-def

RegAlgebra - Boolean Algebra on Spatial Regions
SYNOPSIS
This document describes the boolean arithmetic defined for region expressions.
DESCRIPTION
When defining a region, several shapes can be combined using boolean operations. The boolean operators are (in order of precedence):
Symbol Operator Associativity
---------------------------
! not right to left
& and left to right
^ exclusive or left to right
| inclusive or left to right
For example, to create a mask consisting of a large circle with a smaller box removed, one can use the and and not opera-
tors:
CIRCLE(11,11,15) & !BOX(11,11,3,6)
and the resulting mask is:
1234567890123456789012345678901234567890

You can use several boolean operations in a single region expression, to create arbitrarily complex regions. With the important exception
below, you can apply the operators in any order, using parentheses if necessary to override the natural precedences of the operators.
NB: Using a panda shape is always much more efficient than explicitly specifying "pie & annulus", due to the ability of panda to place a
limit on the number of pixels checked in the pie shape. If you are going to specify the intersection of pie and annulus, use panda
instead.
As described in "help regreometry", the PIE slice goes to the edge of the field. To limit its scope, PIE usually is is combined with other
shapes, such as circles and annuli, using boolean operations. In this context, it is worth noting that that there is a difference between
-PIE and &!PIE. The former is a global exclude of all pixels in the PIE slice, while the latter is a local excludes of pixels affecting
only the region(s) with which the PIE is combined. For example, the following region uses &!PIE as a local exclude of a single circle. Two
other circles are also defined and are unaffected by the local exclude:
CIRCLE(1,8,1)
CIRCLE(8,8,7)&!PIE(8,8,60,120)&!PIE(8,8,240,300)
CIRCLE(15,8,2)
1 2 3 4 5 6 7 8 9 0 1 2 3 4 5

Note that the two other regions are not affected by the &!PIE, which only affects the circle with which it is combined.
On the other hand, a -PIE is an global exclude that does affect other regions with which it overlaps:
CIRCLE(1,8,1)
CIRCLE(8,8,7)
-PIE(8,8,60,120)
-PIE(8,8,240,300)
CIRCLE(15,8,2)

2: . . . . 2 2 2 2 2 2 2 . . . .

The two smaller circles are entirely contained within the two exclude PIE slices and therefore are excluded from the region.
