It’s used in loops in bash, like:

<span style="font-weight:bold;color:#a71d5d;">for</span><span style="color:#323232;"> i </span><span style="font-weight:bold;color:#a71d5d;">in</span><span style="color:#323232;"> 1 2 3
</span><span style="font-weight:bold;color:#a71d5d;">do 
</span><span style="color:#323232;">    </span><span style="color:#62a35c;">echo </span><span style="color:#183691;">"$</span><span style="color:#323232;">i</span><span style="color:#183691;">"
</span><span style="font-weight:bold;color:#a71d5d;">done 
</span>

or

<span style="font-weight:bold;color:#a71d5d;">while </span><span style="color:#323232;">true
</span><span style="font-weight:bold;color:#a71d5d;">do
</span><span style="color:#323232;">    </span><span style="color:#62a35c;">echo </span><span style="color:#183691;">"o/"
</span><span style="font-weight:bold;color:#a71d5d;">done
</span>
