Bash Shell Scripting- Loop Control commands / statements

The video tutorial explains loop control statements, specifically 'break' and 'continue', in shell scripting. It demonstrates how to use these commands to control loop execution, including displaying files with a for loop, filtering text files, and using break and continue to manage loop iterations effectively.

What are break and continue statements primarily used for in loops?

• To initialize variables

• To control loop execution

• To declare functions

• To handle errors

In the shell script example, what command is used to list all files in the current directory?

• pwd

• cat

• echo

• ls

How can you modify the shell script to display only text files?

• Use the command 'ls *'

• Use the command 'ls -l'

• Use the command 'ls -a'

• Use the command 'ls *.txt'

What is the purpose of using a count variable in the loop?

• To count the number of files

• To print all files

• To control the number of loop iterations

• To sort the files

What is the main difference between exit and break in a shell script?

• Both stop the loop

• Both stop the script

• Exit stops the script, break stops the loop

• Exit stops the loop, break stops the script

What happens when a break statement is executed in a loop?

• The loop pauses

• The loop restarts

• The loop terminates immediately

• The loop continues to the next iteration

What is the function of the continue statement in a loop?

• To pause the loop

• To terminate the loop

• To restart the loop

• To skip the current iteration

In the example, what happens when the continue statement is executed?

• The loop terminates

• The current iteration is skipped

• The loop pauses

• The loop restarts

How does the continue statement affect the loop when a condition is met?

• It stops the loop

• It skips the remaining code in the current iteration

• It restarts the loop

• It pauses the loop

Which statement is used to skip the current iteration and move to the next one?

• return

• continue

• exit

• break
