Using Batch Commands
The simplest scripting mechanism is to batch appliance shell commands. For example, to
automatically take a snapshot called newsnap
in the project
myproj
and the filesystem myfs
, put the
following commands in a file:
shares select myproj select myfs snapshots snapshot newsnap
Then ssh
onto the appliance, redirecting standard input to be the
file:
$ ssh root@hostname < myfile.txt
In many shells, you can abbreviate this by using a "here file", where input up to a token is sent to standard input. Following is the above example in terms of a here file:
$ '''ssh root@hostname << EOF shares select myproj select myfs snapshots snapshot newsnap EOF'''
This mechanism is sufficient for the simplest kind of automation, and may be sufficient if wrapped in programmatic logic in a higher-level shell scripting language on a client, but it generally leaves much to be desired.
