My bash script asks user for their first name, last name, address and phone number and writes this information that is input by the user to a file of the format "firstname.lastname"; however I want to repeat this a number of times (I actually wanted to do something like a do..while loop where it runs atleast one time and asks user if they want to continue creating accounts or not but I see there is no do...while for bash it seems). So when I execute this bash script in the terminal it will ask for how many accounts to be made and I provide all the input but the it only runs one time. What am I doing wrong? Here is my script.
#!bin/bash
echo "How many accounts are you creating?"
read num
echo "Enter first name"
read fName
echo "Enter last name"
read lName
echo "Enter address"
read add
echo "Enter phone number"
read phn
echo "Enter gender m for male and f for female"
read gender
if [ "$gender" == "m" ]
then
sex="male"
elif [ "$gender" == "f" ]
then
sex="female"
else
echo"Invalid gender. Restart the script and enter a valid gender"
exit 0
fi
for (( i = 0; i<=num; i++))
do
cat > $fName.$lName <<-EOF
Full Name: $fName $lName
Address: $add
Phone number: $phn
Gender: $gender
EOF
done
将您的输入代码放入循环内,或将该代码包装在函数中,然后在循环内调用该函数。
zerobandwidth's answer is correct, but as an alternative answer, it is in fact quite easy to do what you initially wanted to do:
while true; do
# Your account creation code goes here
echo "Create another account (y/n)?"
read another
if [ "$another" != y ]; then
break
fi
done
