Comments In Configuration Files Or Shell Scripts - ZyXEL Communications NXC2500 User Manual

These files have the same syntax, which is also identical to the way you run CLI commands
manually. An example is shown below.

While configuration files and shell scripts have the same syntax, the NXC applies configuration files
differently than it runs shell scripts. This is explained below.
Table 178 Configuration Files and Shell Scripts in the NXC
Configuration Files (.conf)
• Resets to default configuration.
• Goes into CLI Configuration mode.
• Runs the commands in the configuration file.
You have to run the aforementioned example as a shell script because the first command is run in
Privilege mode. If you remove the first command, you have to run the example as a configuration
file because the rest of the commands are executed in Configuration mode.

Comments in Configuration Files or Shell Scripts

In a configuration file or shell script, use "#" or "!" as the first character of a command line to have
the NXC treat the line as a comment.
Your configuration files or shell scripts can use "exit" or a command line consisting of a single "!" to
have the NXC exit sub command mode.
Note: "exit" or "!'" must follow sub commands if it is to make the NXC exit sub command
mode.
