This does most of the work. At the heart, it calls Net::Telnet::cmd() but it also does some special stuff for Trango.
|
|
|
|
Normally returns the last lines from from the command
|
|
|
|
Also accepts these options:
|
|
|
|
I<decode>
|
|
- if this is true, then it will send the output lines to _decode_lines() and then returns the decoded output
|
|
|
|
I<cmd_disconnects>
|
|
- if this is true, it then sets logged_in() to false, then it will close() the connection and then sets is_connected() to false
|
|
|
|
I<expect>
|
|
- if this is set (usually to 'Success.') it will check for that in the last line of output and if it does not, will return undef because the command probably failed
|
|
|
|
I<args>
|
|
- a string containing the command line options that are passed to the command
