Replace all the break;; with ;;

is_int()

case $1 in

esac

while :

read -ep "How many cars to enter: " tot
is_int "$tot" && [ "$tot" -gt 0 ] && break

It will contain things like:Input: two
line 5: [: two: integer expression expected
Input:
line 5: [: -ge: unary operator expected

@gangsta: you want this then:

How about this example in bash :

while true
do
read -p "How many cars to enter: " tot
[ $tot -ge 0 ] 2>/dev/null && break
echo "Invalid number. re-enter"
done
num=0
while [ $num...

Assumption: Your trying to validate user input against a list of valid responses (in cars_names.txt).

read -p "Car: " cars1
until grep -wiq "$cars1" cars_names.txt && [ -n "$cars1" ]
do
...

You are using a numeric comparison (-eq) for strings. Use string comparison:

until [ "$cars1" = cars_names.txt ]
do
read -ep "Invalid cars. Try again: " cars1
done

read -p "Enter a car model: " car1
grep -w $car1 carMakes.txt
test $? -ne 0 && echo "Car not found, try again please"

You don't really need to use "if" statements, you can use "case":

while true
do
clear
echo "Menu Options: "
echo " 1. Create Script"
echo " 2. Show Script"
echo " 3. Delete...

Usually, you don't.

You could do something like [ -f file ] || echo "doesn't exist" && exit 1 but what if the echo fails for some reason? Then you won't exit.

You could combine statements like...

From man pages:


To be able in ONE command, mkdir that is you will have no other choice but to give the 2 directories in argument and using -p option:

mkdir -p test/test1 test/test2

which...

mkdir -p test/test1/test2
