This article will show you how to use for loop with a counter in Bash.

Syntax:

for (( INITIALIZER; CONDITION; STEP))
do
    # commands
done

Practical example

Edit

xxxxxxxxxx
 
#!/bin/bash
​
for (( i=0; i<5; i++ ))
do  
   echo $i
done

Output:

xxxxxxxxxx

2
3
4

Infinite loop

Edit

xxxxxxxxxx
 
#!/bin/bash
​
for (( ; ; ))
do  
   echo "Hello"
done

Output:

xxxxxxxxxx
 
Hello
