Perl to send cntl c and cntl d

[Ratzie]

I am using the telnet module in perl to telnet to a switch
The funky thing about this switch is that I need to send a cntrl D to get a prompt, then I type a command, and to send the command I need to type a control C.
How do I incorporate this in my script.
Or convert it to actual control characters.
I thought there was a way to do this in vi...

Hi:

You can generate a Ctrl_C with "\003" and Ctrl_D with "\004".

# echo "\003" | cat -etv

# perl -e 'print "\003"' | cat -etv

If you want to create these characters in a 'vi' session, type Ctrl_v and then press either Ctrl_C or Ctrl_D. See the 'ascii(5)' manpages for more information.

perl does have a much nicer way to write that:

# perl -le 'print "\cC\cD"'

# perl -le 'print "\cC\cD"' | perl -nle'print join " ", unpack"C*",$_'
3 4
#

Enjoy, Have FUN! H.Merijn
