I'm trying to use CDOT noninteractively from bash, but running into trouble. Let's say for example you wanted to get a list of volumes on an SVM and then sort by size- there's no sort in the interactive CLI and it asks you to enter text every page of results, so my initial thought was to send the command noninteractively and do what I need done in bash. If you send the command "ssh user@nas volume show -vserver whatever", you get a nicely formatted table without any of the line-splitting, confirmations, or other interactive shell nonsense:

Vserver   Volume       Aggregate    State      Type       Size  Available Used%

--------- ------------ ------------ ---------- ---- ---------- ---------- -----

svm vol1 aggr1 online    RW          2TB     2.00TB    0%

svm vol2 aggr1 online    RW          100GB     100.00GB    0%

This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command?

One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh- 

me@myserver:/home/me $ cat temp

set -units KB

volume show -vserver svm -volume *root

me@myserver:/home/me $ ssh admin@nas < temp

Pseudo-terminal will not be allocated because stdin is not a terminal.

nas::> set -units KB

nas::> volume show -vserver svm -volume *root

Vserver   Volume       Aggregate    State      Type       Size  Available Used%

--------- ------------ ------------ ---------- ---- ---------- ---------- -----

svm

          svm_root

                       aggr1     online     RW    1048576KB   995796KB    5%

nas::>

me@myserver:/home/me $

As you see, as soon as it detects multiple lines, it switches back to the interactive shell. If I had use something with more than a single line of output, it would have given me a couple of lines, asked for "confirmation", and then exited. All the while putting "readability" whitespace inconsistently all over the results.

Any ideas?
