Multi-line commands

I'm using rancid since a couple of months and find it very valuable esp.
when retrieving the same information from a lot of routers/switches.

There are some commands on the catalyst 6500 which require multiple lines of
input (e.g. "clear counters" where you will be prompted for "Do you want to
continue (y/n) [n]?").

With IOS and telnetting into a router I've been successful (iirc) when
separating the commands by "^M" (i.e. Ctrl-M). But that doesn't work with
CatOS and rancid.

How do you deal with multi-line comamnds?

Regards, Arnold

try using the "\\n" construct (an escaped newline). For instance:

$clogin -f $cloginrc -u '$username' -p '$password' -c \"conf net\\nhost\\n$tftphost\\n$tftpacldir/$acls\"

this above is from a perl script - you may only need "\n" if you're
running it from the prompt.

Tnx a lot! If you run the command from the shell a simple backslash does.
