hi,

can you be more precise about what your trying to do?
what's the goal of the for loop?
are you writing a vi script, or are you using vi to write a shell script?

echo "Pattern1"

for (( $i=0;$i<=5;$i++ ))
do
    for (( $j=0;$j<=i;$j++ ))
    do
        echo $j;
    done
    echo "";
done

//i want to print a pattern but it gives me a for syntax error......

[Watael]

for (( i=0; i<=5; i++ ))

i=0 is an assignment, as is i++ inside double parenthesis.
