Inserting Comments
You can insert comments into the script file. Comments begin with a pound sign
(#) in column 1, as shown in the following example:
# The 'echo' command is used to
# output messages to the user’s console.
When you execute a script file, the system does not display the comments on the
user’s console.
Debugging a Script File
To enable the debug trace facility, use the
verbose
command. When you enable
the trace facility, the Technician Interface displays each command read from the
script file before and after its variables have been expanded. For instructions on
using the
verbose
command, see Chapter 2.
Saving and Restoring Variables
To save the current list of local and global variables to a file, use the
save env
command. For example, to save the variables to a file named test, enter the
following command:
save env test
To read and execute the commands in a Technician Interface script file, and to
ensure that the router saves (restores) all local variables when the script ends, use
the
source env
command.
For example, to run the script file test on volume 2, and to restore upon
completion all local variables saved previously to test, enter the following
command:
source env 2:test
To locate script errors, use the
verbose
on
command and then use the
source env
command. The Technician Interface displays each line from the file before it
executes the line, enabling you to easily locate errors.
For more information about the
save env
and
source env
commands, see
Chapter 2.
