The result was not correct I have had to adjust the code to get the correct response but am unable to.
fil_len=`wc -l < input_file`
if [ fil_len > 3 ]; then
email file
elif [ file_len < 3 ]; then
delete empty file
fi
The test statement will not accept the value from fil_len, I have output to the screen to see if it is valid and it gives a number but not sure if it is char or numeric.
The output looks like this;
9
No matter what I do it will only select the first part of the statement as true. Regardless of the lines in the file.
All in a Korn Shell (KSH)
sorry for the premature elation!!!! (hair trigger trouble you know)

execute
EXECUTE(7) PostgreSQL 9.2.7 Documentation EXECUTE(7)
NAME
EXECUTE - execute a prepared statement
SYNOPSIS
EXECUTE name [ ( parameter [, ...] ) ]
DESCRIPTION
EXECUTE is used to execute a previously prepared statement. Since prepared statements only exist for the duration of a session, the
prepared statement must have been created by a PREPARE statement executed earlier in the current session.
If the PREPARE statement that created the statement specified some parameters, a compatible set of parameters must be passed to the EXECUTE
statement, or else an error is raised. Note that (unlike functions) prepared statements are not overloaded based on the type or number of
their parameters; the name of a prepared statement must be unique within a database session.
For more information on the creation and usage of prepared statements, see PREPARE(7).
PARAMETERS
name
The name of the prepared statement to execute.
parameter
The actual value of a parameter to the prepared statement. This must be an expression yielding a value that is compatible with the data
type of this parameter, as was determined when the prepared statement was created.
OUTPUTS
The command tag returned by EXECUTE is that of the prepared statement, and not EXECUTE.
EXAMPLES
Examples are given in the EXAMPLES section of the PREPARE(7) documentation.
COMPATIBILITY
The SQL standard includes an EXECUTE statement, but it is only for use in embedded SQL. This version of the EXECUTE statement also uses a
somewhat different syntax.
