Not sure, I don't know you script and don't know how you want to handle it exactly, but if you wanted to cat files already stored in LOG1 LOG2 and LOG3, (without doing the stunt with LOG I mentioned before), with bash you could try this:
Code:
for i in {1..3}; do
 x=LOG$i
 cat ${!x} >>mySingleLogfile.log
done

I hope this doesn't complicate the situation further Smilie

Edit: Yet another option/variant:
Code:
for i in $LOG1 $LOG2 $LOG3; do
 cat $i >>mySingleLogfile.log
done

LOG2(3) 						     Linux Programmer's Manual							   LOG2(3)

NAME

       log2, log2f, log2l - base-2 logarithmic function

SYNOPSIS

       #include <math.h>

       double log2(double x);
       float log2f(float x);
       long double log2l(long double x);

       Link with -lm.

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       log2(), log2f(), log2l():
	   _XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
	   or cc -std=c99

DESCRIPTION

       The log2() function returns the base 2 logarithm of x.

RETURN VALUE

       On success, these functions return the base 2 logarithm of x.

       For special cases, including where x is 0, 1, negative, infinity, or NaN, see log(3).

ERRORS

       See math_error(7) for information on how to determine whether an error has occurred when calling these functions.

       For a discussion of the errors that can occur for these functions, see log(3).

VERSIONS

       These functions first appeared in glibc in version 2.1.

CONFORMING TO

       C99, POSIX.1-2001.  The variant returning double also conforms to SVr4, 4.3BSD.

SEE ALSO

       cbrt(3), clog2(3), log(3), log10(3), sqrt(3)
