This is my file for reading lines from input.txt and printing them out.
#!/bin/bash
read -p "Enter an apartment number:" aptNumber
while IFS=$' \n' read -r firstName lastName leaseStart leaseEnd balance;
do
echo "Apartment Number: $aptNumber"
echo "Tenant Name: $lastName,$firstName"
echo "Lease Start: $leaseStart"
echo "Lease End: $leaseEnd"
echo "Current Balance: $balance"
done < input.txt
input.txt
John Doe
07/07/19 07/07/20
900
This is the output it’s giving me
Enter an apartment number:001
Apartment Number: 001
Tenant Name: Doe,John
Lease Start:
Lease End:
Current Balance:
Apartment Number: 001
Tenant Name: 07/07/20,07/07/19
Lease Start:
Lease End:
Current Balance:
Apartment Number: 001
Tenant Name: ,900
Lease Start:
Lease End:
Current Balance:
This is the output i need
Apartment Number: 001
Tenant Name: Doe,John
Lease Start: 07/07/19
Lease End: 07/07/20
Current Balance: 900
>Solution :
I suggest with bash:
read -r -p "Enter an apartment number:" aptNumber
while read -r first last; do
read -r start end
read -r balance
echo "Apartment Number: $aptNumber"
echo "Tenant Name: $last,$first"
echo "Lease Start: $start"
echo "Lease End: $end"
echo "Current Balance: $balance"
done < input.txt
Every read in this loop reads one line of input.txt.
Output:
Enter an apartment number:42 Apartment Number: 42 Tenant Name: Doe,John Lease Start: 07/07/19 Lease End: 07/07/20 Current Balance: 900
