Here is the basic syntax for a for loop in KSH (Korn Shell):
for variable in list; do commands done
The for loop will execute the commands for each value in the list. The variable will be set to the current value of the list on each iteration.
Here is an example of a for loop that counts from 1 to 10:
for i in {1..10}; do
echo $i
done
You can also specify a range of numbers using a step size:
for i in {1..10..2}; do
echo $i
done
This will count from 1 to 10 with a step size of 2, resulting in the output 1 3 5 7 9.
You can also use the (( )) syntax to iterate over a range of numbers with a step size of 1:
for ((i=1; i<=10; i++)); do echo $i done
This will count from 1 to 10 with a step size of 1, resulting in the output 1 2 3 4 5 6 7 8 9 10.
For more information on using for loops in KSH, you can consult the KSH manual or online documentation.
