Why not ? rename is for renaming right ?! what expression you are thinking of ?

Code:
 
# ls
green_1234_colour.max  red_1234_pen.max  yellow1234flower.max
# rename 1234 9846 *
# ls
green_9846_colour.max  red_9846_pen.max  yellow9846flower.max

ns_rand(3aolserver)					    AOLserver Built-In Commands 				       ns_rand(3aolserver)

__________________________________________________________________________________________________________________________________________________

NAME

       ns_rand - commands

SYNOPSIS

       ns_rand ?max?
_________________________________________________________________

DESCRIPTION

       ns_rand	generates  a  cryptographically-secure random number.  If max is not specified, the random number is a floating-point value n such
       that 0.0 <= n < 1.0.

       If max is specified, it must be a positive integer between 0 and 2147483647.  The return value is an integer value such that 0 <= n <= (max
       - 1).

       Internally  ns_rand is implemented with the drand48(3) and lrand48(3) standard library functions.  An internal random seed is generated the
       first time ns_rand is called after the server starts.

EXAMPLES

	nscp> ns_rand
	0.39938485692

	nscp> ns_rand 10
	7
