Question function

The shell script below (test.cmd) gives me the error 'test.cmd: function: not found' However if I use it like function_name() { code } it works fine. Problem is that i am studying the system code and its using it like function function_name { code }

Can anybody guide me on how to use function function_name { code } in shell scripts.
Code:
#ParseRowcount()
function ParseRowcount
{

echo "entered ParseRowcount"
VALUES=$1
echo $VALUES
TOTAL=0
for V in $VALUES
do
        TOTAL=`expr $TOTAL + 1 `
        echo "entered loop"
done

}

#ParseLog()
function ParseLog
{

echo "entered ParseLog"
ROWS_LOADED=`grep "successfully" $1 | cut -d"R" -f1`
echo $ROWS_LOADED
ParseRowcount "$ROWS_LOADED"; ROWS_LOADED=$TOTAL
echo "Rows loaded................${ROWS_LOADED}"

}

ParseLog ./test1.txt

Re: function

Quote:
function ParseRowcount
imho, should be written as:

ParseRowcount(){
...
}

note the inclusion of bracket and omission of "function" word.

function

dear kanang,
thanks for ur response . i know it works when used like function_name () { code }, but since system code which i'm going thro' its coded like function function_name { code }. So i would like to know how does it work in this case.

The syntax:
Code:
function some_function
{
[...]
}

is not always portable. I know the korn shell can use this syntax, but many shells do not. The POSIX standard that should work with any reasonably new shell would be to use the syntax:
Code:
some_function () {
[...]
}

Hope that clears this up...
