Top Forums Shell Programming and Scripting Why the results of these two code fragments are not the same? Post 303030164 by Don Cragun on Wednesday 6th of February 2019 09:59:32 PM

Maybe...

Since both of your scripts are comparing every element of the operand list to every element of the operand list, one might expect that there would be at least two cases where the operands would be identical. Those cases would be when you're comparing the first operand to the first operand (i.e., $HOME/Documents/ to $HOME/Documents/) and when you're comparing the second operand to the second operand (i.e., $HOME/Downloads/ to $HOME/Downloads/).

Maybe there is a logical mistake in both scripts???

What is the logic in both of your scripts behind the variable named counter? Why does it matter what the value of $counter is when trying to determine whether or not two command-line arguments are the same?
