In the previous section, we discussed about how continue can be used to exit from the current iteration of a loop. The break command is another way to introduce a new condition within a loop. Unlike continue, however, it causes the loop to be terminated altogether if the condition is met.
In the for_12.sh script, we check the directory's content. If the directory is found, then we are exiting the loop and displaying the message that the first directory is found:
#!/bin/bash rm -rf sample* echo > sample_1 echo > sample_2 mkdir sample_3 echo > sample_4 for file in sample* do if [ -d "$file" ]; then break; fi done echo The first directory is $file rm -rf sample* exit 0
Let's test the program, as follows:
