In this article, we will see how to use "continue" in an easy FOR loop example in bash.
FOR loops work similar to FOR loops in other programming languages. It executes statement or statements of code with iteration. When we need to keep iteration going on for a particular case, we can use "continue" in bash.
Lets look to its syntax.
if [ condition ];
continue
fi
Lets see it in bash shell scripting example.
As above output indicates, we created a variable and a FOR loop. Variable starts with initial value as 0. Each cycle, it iterates plus one and echo it to terminal. When it reaches "4", we check it with "IF", and if it is 4, we just echo out that "IF" block has been executed and saying the loop keep going its cycle. "Break" ends to loop and control passes to next statement following the FOR loop, "continue" works opposite and tells loop to keep going.
