I do not see a syntax error, but you should correct the shebang (1st line) to
Code:
#!/bin/bash

Maybe you are on Solaris and failing to run /bin/bash falls back to /bin/sh that does not understand $( )
There is a second problem,
> "test.log"
overwrites the file each time.
Either change to
>> "test.log"
Or move it to the "done" as follows
Code:
...
done > "test.log"

that is more efficient because it opens+creates the file once (when the loop starts).
Or
Code:
...
done >> "test.log"

That opens+appends it once.

NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling SYNOPSIS
hostname | user@hostname [-l login_name] [command] hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name] [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command] DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally. OPTIONS
