Easiest and most readable way to execute multiple commands using ssh on solaris
I think this is what you want. It's one inline script calling a ksh which has two parts, the one surrounded by double quotes (") gets expanded on the local machine, allowing remote $variables to be set, then the second part is surrounded by single quotes (') which does not get expanded locally so you can use remote variables such as the $file one shown.

I think it looks quite clean, readable and self contained and you can quite a lot of commands run in the single quote section.

Code:
echo "OUTPUT"
dir="/tmp"
mask="*.tar"
ssh -n $USER@$MACHINE /bin/ksh -c ":
        # this part gets expanded locally so use only to pass in variables
             dir='$dir'
     mask='$mask'
"'
     # This gets run remotely do not use single quotes
             echo "using single quotes ('\'') is tricky"
             echo "searchng: $dir; for $mask;"
     cd "$dir"
     pwd
             for file in $(ls -t $mask); do
                         echo "found: $file"
            done
'
OUTPUT
using single quotes (') is tricky
searchng: /tmp; for *.tar;
/tmp
found: Another.tar
found: Save.tar
