It's always nice to get feedback on why, so that we're more likely
to understand similar questions in future. For example, you never
really explained whether "command no problem, write in red until exit
or reboot" was something you want (everything red, or just prompts
in red?) or something you don't want (nothing red after the one
string) and whether you rebooted to clear a problem demonstrate that
red prompts were lost (against your wishes). We don't read minds.

Sure:

$ ./my-script ; echo -n "the string"

or:

$ ./my-script ; echo -n -e "\e[0;31mthe string\e[m"

if you want "the string" in red.

So, using cat to stand for your script, and sleep to stand for the
time it takes your script to run:

wren!david 12:46:59 ~ $ cat /etc/network/interfaces ; date ; sleep 5 ; echo -n -e "\e[0;31mthe string\e[m"
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback
