Too many things are wrong here -

1) "exec" or "execute" is a sqlplus command that wraps the "begin ... end" block around whatever follows it. So you cannot put a "begin ... end" block around "exec" itself.

2) If the input parameter is a string, then add the string delimiter to it, otherwise Oracle will consider it an identifier.

3) Of course, just because the input parameter is declared a VARCHAR2 in the procedure signature doesn't mean that you cannot pass a number/integer etc. Oracle does an implicit conversion of the passed value to VARCHAR2 in that case.

4) If the input parameter is a string that has multiple words separated by whitespace, then enclose it within double-quotes in the shell script, at the function call, that is.

HTH,

pwd

PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME

     pwd -- return working directory name

SYNOPSIS

     pwd [-LP]

DESCRIPTION

     The pwd utility writes the absolute pathname of the current working directory to the standard output.

     Some shells may provide a builtin pwd command which is similar or identical to this utility.  Consult the builtin(1) manual page.

     The options are as follows:

     -L      Display the logical current working directory.

     -P      Display the physical current working directory (all symbolic links resolved).

     If no options are specified, the -P option is assumed.

ENVIRONMENT

     Environment variables used by pwd:

     PWD  Logical current working directory.

DIAGNOSTICS

     The pwd utility exits 0 on success, and >0 if an error occurs.

STANDARDS

     The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

SEE ALSO

     builtin(1), cd(1), csh(1), sh(1), getcwd(3)

BUGS

     In csh(1) the command dirs is always faster because it is built into that shell.  However, it can give a different answer in the rare case
     that the current directory or a containing directory was moved after the shell descended into it.

     The -L option does not work unless the PWD environment variable is exported by the shell.
