Check whether one number equals another number in bash

Question

I\'ve been trying to compare whether two numbers in Bash are equal (and print a message if they are equal), but I\'m getting some strange error messages for this simple prog

Answer 1

For the first error message, remove the dollar sign $ and no spaces are allowed around the equal sign =

x=3

For the second error message, insert a space and a dollar sign $ before x and a space after 3

if [ $x -eq 3 ]

As @loentar correctly pointed out, it must be -eq and neither = nor ==.
