2.1.5. CLI Scripts Chapter 2. Management and Maintenance in a directory under the root called /scripts. SCP uploading is discussed in detail in Section 2.1.6, "Secure Copy". 3. Use the CLI command script -execute to run the script file. The CLI script command is the tool used for script management and execution. The complete syntax of the command is described in the CLI Reference Guide and specific examples of usage are detailed in the following sections. See also Section 2.1.4, "The CLI" in this manual. Only Four Commands are Allowed in Scripts The commands allowed in a script file are limited to four and these are: • add • set • delete • cc If any other command appears in a script file, it is ignored during execution and a warning message is output. For example, the ping command will be ignored. Executing Scripts As mentioned above, the script -execute command launches a named script file that has been previously uploaded to the NetDefend Firewall. For example, to execute the script file my_script.sgs which has already been uploaded, the CLI command would be: gw-world:/> script -execute -name=my_script.sgs Script Variables A script file can contain any number of script variables which are called: $1, $2, $3, $4......$n The values substituted for these variable names are specified as a list at the end of the script -execute command line. The number n in the variable name indicates the variable value's position in this list. $1 comes first, $2 comes second and so on. Note: The symbol $0 is reserved Notice that the name of the first variable is $1. The variable $0 is reserved and is always replaced before execution by the name of the script file itself. For example, a script called my_script.sgs is to be executed with IP address 126.12.11.01 replacing all occurrences of $1 in the script file and the string If1 address replacing all occurrences of $2. The file my_script.sgs contains the single CLI command line: add IP4Address If1_ip Address=$1 Comments=$2 To run this script file after uploading, the CLI command would be: > script -execute -name=my_script.sgs 126.12.11.01 "If1 address" 45
