Question Enter q for quit not working
I'm using a while loop with an if statement. When the user choses a number, it will display a list of files. That works, the problem is q for quit won't exit script. How can I fix this?

Hi.

Code:
break

will ordinarily end an iterative cycle. Without more details (i.e. seeing your script), I can't be more specific than that!

Network Code for enter q to quit
Code:
echo "Enter week number or q to quit: "
read num
while $num != q
do
       if [ $num -lt 4 ]
          then
             echo "The files submitted in week $num are"
                   ls ../week$num
           else
              echo "Incorrect week number!"
      fi
      echo "Enter week number or q to quit: "
      read num
done

the loop has to continue until user tells it to quit, but I can't get the program to take the q. It just keeps going with the script.

After fixing the bad test on the while statement, it worked for me in both bash and kshell.

Code:
#!/usr/bin/env ksh
echo "Enter week number or q to quit: "
read num
set -x                      # add this line to help debug the loop
while  [[ $num != q ]]
do
        if  [[ $num < 4 ]]
        then
                echo "The files submitted in week $num are"
                ls ../week$num
        else
                echo "Incorrect week number!"     
        fi
        echo "Enter week number or q to quit: "
        read num
done

Not sure why it won't work, but I tried agama's suggestion and it still won't work. Any other suggestions.

Since the code works for me in my environment, the only way I might suggest something is if you execute the script with the set -x in place and posting the ouput when you run the script.

Code:
#!/bin/bash
read -p "Enter week number or q to quit: " num
 while [ $num != "q" ] ;
do
       if [ $num -lt 4 ]
          then
             echo "The files submitted in week $num are"
                   ls ../week$num
           else
              echo "Incorrect week number!"
      fi
      read -p "Enter week number or q to quit: " num
done
