 As with other languages, you can use `continue` and `break` with your bash scripts as well:
 
 * `continue` tells your bash script to stop the current iteration of the loop and start the next iteration.
+
+The syntax of the continue statement is as follows:
+
+```bash
+continue [n]
+```
+
+The [n] argument is optional and can be greater than or equal to 1. When [n] is given, the n-th enclosing loop is resumed. continue 1 is equivalent to continue.
+
+```bash
+#!/bin/bash
+
+for i in 1 2 3 4 5
+do
+    if [ $i –eq 2 ] 
+    then
+        echo “skipping number 2”
+    continue
+    fi
+    echo “I is equal to $i”
+done
+```
+
+We can also use continue command in similar way to break command for controlling multiple loops.
+
+
 * `break` tells your bash script to end the loop straight away.
+
+The syntax of the break statement takes the following form:
+
+```bash
+break [n]
+```
+[n] is an optional argument and must be greater than or equal to 1. When [n] is provided, the n-th enclosing loop is exited. break 1 is equivalent to break.
+
+Example:
+
+```bash
+#!/bin/bash
+
+num=1
+while [ $num –lt 10 ] 
+do
+    if [ $num –eq 5 ] 
+    then
+        break
+    fi
+    ((num++))
+done
+echo “Loop completed”
+```
+
+We can also use break command with multiple loops. If we want to exit out of current working loop whether inner or outer loop, we simply use break but if we are in inner loop & want to exit out of outer loop, we use break 2.
+
+Example:
+
+```bash
+#!/bin/bash
+
+for (( a = 1; a < 10; a++ ))
+do
+    echo “outer loop: $a”
+    for (( b = 1; b < 100; b++ ))
+    do
+        if [ $b –gt 5 ] 
+        then
+            break 2
+        fi
+    echo “Inner loop: $b ”
+    done
+done
+```
+
+The bash script will begin with a=1 & will move to inner loop and when it reaches b=5, it will break the outer loop.
+We can use break only instead of break 2, to break inner loop & see how it affects the output.
