[rancid] Cisco commands containing ';'...

[Jon Peatfield]

I may have been expecting too much but I wanted to run:

clogin -c 'conf t; boot system flash:bootimage1;flash:bootimage2; exit' a b c

to set the boot path on a set of identical switches. Of course clogin
splits the command at the ; in the middle of the boot system command so
that fails...

So I thought I need to use -x and pass a file with the lines but that also
fails because it seems that clogin actually joins the lines from the file
with ; and then treats is just as if it was a -c option (ie it splits it
at all ; again).

So is there a way to bypass the split and get a real ; into a command?

A glance through the code doesn't suggest anything obvious but I may be
missing a trick...

Have you tried an escape "\" ?

Not sure it would help, but worth a try.

that will not work. We'd have to add logic to do that. I'd lean toward
doing that. one hack option would be to encode it as its ascii value;
59 or 0x3b. But, I dont recall off the top how to do that encoding for
tcl's printf (expect's send).

It works if I put \073 instead of ; e.g

clogin -x filename ...

where filename contains:

conf t
boot system
flash:bootimage1\073flash:bootimage2
exit

ie putting \073 where I want the ;...

Excellent!

Many thanks.
