You're using the filename instead of the content of the file and it's more efficient to call the date command once:

Code:
#!/bin/ksh

dd=$(date "+%Y%m%d")

while read i
do
  temp=`echo $i | awk -F"." -v d=$dd '{print $1 "_" d FS $2}'`
  mv "$i" "$temp"
done < myfiles.lst

Actualy this command is sufficient to do the job:

Code:
awk -F"." -v d=$(date "+%Y%m%d") '{system("mv " $0 " " $1 "_" d FS $2)}' myfiles.txt

roundup-ctl

ROUNDUP-CTL(1)						      General Commands Manual						    ROUNDUP-CTL(1)

NAME

       roundup-ctl - roundup server control interface

SYNOPSIS

       roundup-ctl [options] command

DESCRIPTION

       roundup-ctl  is	a front end to the roundup server.  It is designed to help the administrator control the functioning of the roundup server
       daemon. This script mimics most of the behaviour of a regular init script, but works as a front end to the runit  package  to  control  the
       roundup	service. So, in order to use this, you need the runit package, too. Please note that using this script is mostly incompatible with
       having roundup controlled by runit directly in the form of automatic startup.

       The roundup-ctl script returns a 0 exit value on success, and >0 if an error occurs. For more details, view the comments in the script.

OPTIONS

       -d directory
	      Use given directory as service directory.

COMMANDS

       The command can be any one or more of the following options:

       start  If the roundup server is not runinng, start it. If the server stops, restart it.	stop Stops the roundup server.	status Print  sta-
	      tus of the roundup server.

SEE ALSO

       roundup-server(1) runsvctrl(8) runsvstat(8) svwaitdown(8)
