I'm working on a simple game that I'm programming in shell for a college assignment and I don't know why my last if doesn't work properly:
#! /bin/bash
sort -n num.txt > sorted_nums.txt
pc_num=`head -1 sorted_nums.txt`
read $user_num
if [ $user_num = $pc_num ]
then
echo "You are correct"
else
echo "You're wrong, the right answer was $pc_num"
fi
The problem comes in the if statement because when I run the programme it will always print the error:
./nums.sh: line 9: [: =: binary operator expected
I have also tried replacing = with -eq and still doesn't work
And then print:
You're wrong, the right answer was $pc_num
Thank you!

Well, you are being directed to the wrong line. Actually you are reading the user input wrong. It must be read user_num
without the $
