Understanding The Built-In Cli Functions - Oracle ZFS Storage Appliance Administration Manual

dory:> script
("." to run)>
2.
At the script environment prompt, you can input your script, finally entering "."
alone on a line to execute it:
dory:> script
("." to run)> for (i = 10; i > 0; i--)
("." to run)> printf("%d... ", i);
("." to run)> printf("Blastoff!\n");
("." to run)> .
10... 9... 8... 7... 6... 5... 4... 3... 2... 1... Blastoff!
3. If your script is a single line, you can simply provide it as an argument to the
script command, making for an easy way to explore scripting:
dory:> script print("It is now " + new Date())
It is now Tue Oct 14 2009 05:33:01 GMT+0000 (UTC)

Understanding the Built-in CLI Functions

Of course, scripts are of little utility unless they can interact with the system at large. There are
several built-in functions that allow your scripts to interact with the system:
