Unfortunately, this does not work. See screen output below.

/tmp$ cat test.sh
#!/usr/bin/env bash

/opt/local/bin/octave -q << EOF
strtrim(help('help'))
EOF

/tmp$ ./test.sh
`help' is a function from the file /opt/local/share/octave/3.2.4/m/help/help.m

 -- Command: help NAME
     Display the help text for NAME.  If invoked without any arguments,
     `help' prints a list of all the available operators and functions.

     For example, the command `help help' prints a short message
     describing the `help' command.

     The help command can give you information about operators, but not
     the comma and semicolons that are used as command separators.  To
     get help for those, you must type `help comma' or `help semicolon'.
