Using the List Function
The message about pseudo-terminal allocation is due to the ssh client; the issue that this
message refers to can be dealt with by specifying the "-T" option to ssh.
Using the List Function
In a context with dynamic children, it can be very useful to iterate over those children
programmatically. This can be done by using the list function, which returns an array of
dynamic children.
1.
The following example script iterates over every share in every project, printing
out the amount of space consumed and space available:
script
run('shares');
projects = list();
for (i = 0; i < projects.length; i++) {
run('select ' + projects[i]);
shares = list();
for (j = 0; j < shares.length; j++) {
run('select ' + shares[j]);
printf("%s/%s %1.64g %1.64g\n", projects[i], shares[j],
get('space_data'), get('space_available'));
run('cd ..');
}
run('cd ..');
}
2.
Here is the output of running the script, assuming it were saved to a file named
"space.aksh":
% ssh root@koi < space.aksh
