the "2" instead of " " " was typo, does it work for you? strange because it doesnt display output of
Code:
choice1=$(ls -l|awk '{print $9 $1}')

or
Code:
choice2=$(ls | wc -c)

it just exits when I enter " 3 "

I read online tutorials and got a Advanced Bash-Scripting Guide but I need a while with scripts to be on the level when I look at the code and find errors. Just now I am on the errors making level . . .

I am pasting full script, can you tell me if that works for as it should,
Code:
#!/bin/bash
choice=0
choice1=$(ls -l|awk '{print $9 $1}')
choice2=$(ls | wc -c)
choice3=exit

while [ $choice -ne 3 ]
do

clear

echo " ========================================= "
echo " = 1) display diles and permissions only = "
echo " = 2) calculate numbers of bytes         = "
echo " = 3) exit                               = "
echo " ========================================= "

echo -n "       enter a number : "
read choice

case "$choice" in
1 ) echo " $choice1 "  ;;
2 ) echo " $choice2 " ;;
3 ) exit ;;
esac
done

thanks.
