overwrite an NVRAM configuration previously written

I upgraded the IOS on several of my routers. Now i'm tyring to add netflow and save the config. But I cannot get NCM 5.5 to overwrite NVRAM in a command script.

Sample script. (just for the write function)

${CRLF}

This is what you see if you telnet into the router and type write.

Overwrite the previous NVRAM configuration?[confirm]

Has anyone else run into this?

Yah we have run into this, you can just add a "y" to the next line, and that will confirm for you and save the config. So the script should look like this:

Let me know if this works.

I believe I tried that. But I’m not sure if I put the blank line between the wr and Y when I tried it.

Unfortunately I couldn’t wait for your response and saved the config on all the routers the old fashioned way so I’m unable to test your script.
