Menus and Return commands in Shell; Stuck in a loop
0
I have a menu that uses the case command to switch to a sub-menu that then calls to a shell script (.functions) as follows:
. .functions
loop=z
while [ "$loop" = z ]
do
clear
tput cup 3 12; echo "Student Program Information"
tput cup 4 12; echo "==========================="
printf "n"
tput cup 6 12; echo "Sort by: "
tput cup 7 15; echo "L - Last Name"
tput cup 8 15; echo "P - Programs "
tput cup 9 15; echo "C - Credits "
tput cup 10 15; echo "Any - ID "
printf "n"
tput cup 12 12; echo "Enter your choice: "
tput cup 12 32; read thing || continue
case $thing in
[Ll]) sort_lname ;;
[Pp]) sort_program ;;
[Cc]) sort_credits ;;
*) sort_ID ;;
esac
done
my .functions file then formats and displays the code like so:
sort_ID()
{
sort -k 1 -t: student_data > sorted_records1;
clear;
awk -F: ' { printf "%-12s %-12s %-12s %-24s %-12sn", $1, $2, $3, $4, $5 } ' sorted_records1
printf "n"
printf "n"
echo "The total number of records: "
wc -l < student_data
printf "n"
echo "Press ENTER to continue..."
read continue
}
sort_lname()
{
sort -k 2 -t: student_data > sorted_records2;
clear;
awk -F: ' { printf "%-12s %-12s %-12s %-24s %-12sn", $1, $2, $3, $4, $5 } ' sorted_records2
printf "n"
printf "n"
echo "The total number of records: "
wc -l < student_data
printf "n"
echo "Press ENTER to continue..."
read continue
}
sort_program()
{
sort -k 4 -t: student_data > sorted_records3;
clear;
awk -F: ' { printf "%-12s %-12s %-12s %-24s %-12sn", $1, $2, $3, $4, $5 } ' sorted_records3
printf "n"
printf "n"
echo "The total number of records: "
wc -l < student_data
printf "n"
echo "Press ENTER to continue..."
read continue
}
sort_credits()
{
sort -k 5 -t: -n student_data > sorted_records4;
clear;
awk -F: ' { printf "%-12s %-12s %-12s %-24s %-12sn", $1, $2, $3, $4, $5 } ' sorted_records4
printf "n"
printf "n"
echo "The total number of records: "
wc -l < student_data
printf "n"
echo "Press ENTER to continue..."
read continue
}
What I'd like to happen is that after I have chosen an option and it's displayed, I press enter and am brought back up two menus, since the way it is set up now I am stuck in a loop of viewing my records. Any help is appreciated. Thanks!

Had a thought. Is there a way I can tell the script to run a file when pressing enter. So instead of it saying read continue and taking me up one menu, it will just clear and rerun the script to get me back to the starting menu?
