NetCI allows you to easily redirect input and output instead
of using $STDIN and $STDLIST.
You redirect input through script files and output through log files.
Figure 8-3 “Redirecting Input and Output” shows NetCI installed
on node K with input and output
passing through a virtual terminal configured on the remote nodes.
Commands are transmitted over network connections through VT and
are executed on the remote nodes. This figure shows that the script
file contains the input, while the log file contains the output.
Scripting and logging may be used separately or simultaneously.
When you use the scripting and logging operational modes, NetCI
redirects the input and output.
The input is redirected from the keyboard to the script file
and the output is redirected from the terminal screen to the log
file. The different modes of operation are:
Scripting only (input from script
file and output to screen)
Logging only (input from keyboard and output to
log file and screen)
Scripting and logging (input from script file and
output to log file and not to screen)
No scripting and logging. (interactive session where
input is from keyboard and output is to screen)
