Answer 1

I was struggling to combine both multiple lines feed into command and getting its results into a variable (not a file) and come up with this solution:

    FRA_PARAM="'db_recovery_file_dest'"
    FRA=$(
    sqlplus -S "/as sysdba" <

Please note that single-quotes word was substituted, because otherwise I was receiving its autosubstitution to double quotes... ksh, HP-UX.

Hopefully this will be helpful for somebody else too.
