Network Simple while-loop problem
Maybe because its Friday, but I can't get a simple while loop to work!

Code:
#!bin/bash
 
i=0
while [ $i < 20  ]
do
 
echo "Hello"
 
((i++))
 
done

Hi.

Arithmetic operations are done with -lt, -eq, -gt, etc.

So...

Code:
while [ $i -lt 20  ]

I never use this notation, although it should work:

Code:
((i++))

Try:
Code:
i=$((i + 1))
