In addition to what wbport suggested, there are some other alternatives in cases where the strings you are looking for all occur on a single line in your log files...

If the strings you are searching for always appear in the same order on a line (i.e., A1 followed by A2 followed by A3), you can use:
Code:
grep 'A1.*A2.*A3' file

If they can appear in any order, try one of the following:
Code:
egrep 'A1.*A2.*A3|A1.*A3.*A2|A2.*A1.*A3|A2.*A3.*A1|A3.*A1.*A2|A3.*A2.*A1' file
grep -e 'A1.*A2.*A3' -e 'A1.*A3.*A2' -e 'A2.*A1.*A3' -e 'A2.*A3.*A1' -e 'A3.*A1.*A2' -e 'A3.*A2.*A1' file

or create a file containing your REs (named REfile in this example) containing:
Code:
A1.*A2.*A3
A1.*A3.*A2
A2.*A1.*A3
A2.*A3.*A1
A3.*A1.*A2
A3.*A2.*A1

and then use:
Code:
grep -f REfile file

Note that if the strings you're searching for do not all appear on a single line, the code suggested by wbport will only print lines containing A3 (not lines containing just A1 or A2). If you want to print all lines containing A1, A2, or A3 but only print those lines if the file contains all three strings, you need an extra level of grep to print the final results (i.e. read some of your files four times when looking for 3 strings; three times to find the names of files that contain each string and a final time to print all three strings (using OR instead of AND). Or, you can use awk to read the file once, gather lines that match any of your strings and keep track of which strings have been found, and then print all matching lines at the end if all of your strings have been found. If this is what you need, we can help you figure out a way to do that, but I'm not going to try to do it here if you don't need to do that. Your description of your problem isn't clear as to the extent of the problem you're trying to solve.

xmscrollvisible

XmScrollVisible(library call)											     XmScrollVisible(library call)

NAME

       XmScrollVisible -- A ScrolledWindow function that makes an invisible
	descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>
       void XmScrollVisible(
       Widget scrollw_widget,
       Widget widget,
       Dimension left_right_margin,
       Dimension top_bottom_margin);

DESCRIPTION

       XmScrollVisible makes an obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible. The function re-
       positions the work area and sets the specified margins between the widget and the nearest viewport boundary. The widget's location relative
       to  the	viewport determines whether one or both of the margins must be adjusted. This function requires that the XmNscrollingPolicy of the
       ScrolledWindow widget be set to XmAUTOMATIC.

       scrollw_widget
		 Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured descendant.

       widget	 Specifies the ID of the widget to be made visible.

       left_right_margin
		 Specifies the margin to establish between the left or right edge of the widget and the associated edge  of  the  viewport.   This
		 margin is established only if the widget must be moved horizontally to make it visible.

       top_bottom_margin
		 Specifies  the  margin  to  establish between the top or bottom edge of the widget and the associated edge of the viewport.  This
		 margin is established only if the widget must be moved vertically to make it visible.

       For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3)
