To do this you need to start tclsh and create the file puts [open "flash:filename" w+] {  now don’t press enter but just paste in your config lines and then } and ENTER. tclquit to exit tclsh. Now you’ll have your config snippet in flash:filename and you can use it to append to your config. Would be a good idea to check it with `more flash:filename’ just to be sure that you have everything in place and no characters were left outside. As always, more info on Cisco’s webpage
