Testing the last character in a string
Hi
In the shell scripted I'm trying to write!
I would like to test the last character in a string. The string is a path/directory and I want to see if the last character is a '/'.
The string (path/directory) is inputted by a user. If the '/' character isn't present then I want to be able to append this character to the string.
I started to right this in awk then scrapped it as I thought there must be an easier way?
Thanks in advance

Is there a command that can check how long a user-entered string is?
Please don't give me a code, just the name of the command (playing around yourself is much more fun than just pasting code)
