Cisco TCL script write stdout to tftpboot

I want to log the following stdout:

router(config)#scripting tcl init tftp://192.168.1.1/remote-ping.tcl

=====================================
tclsh
proc rping {} {
foreach address {
192.168.1.1
192.168.2.1
} { ping $address re 50 si 1500
}

router(tcl)#rping

Type escape sequence to abort.
Sending 50, 1500-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Sending 50, 1500-byte ICMP Echos to 192.168.2.1, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This script will be executed remotly via cron job, and I want to log all the ICMP-replies.

Any suggestion !!
