Bash – Get last character in string

To get last character in a string in Bash scripting, you can use parameter expansion and substring expansion as shown in the following expression.

${string: -1}

Please note the spacing between : and -1.

In the following script, we take a string in str. We get the last character in this string and echo it to output.
