How to sort characters in a string?

command-line, sorting, unix

Solution

echo cba | grep -o . | sort |tr -d "\n"

Problem

I would like to sort the characters in a string. E.g. ``` echo cba | sort-command abc ``` Is there a command that will allow me to do this or will I have to write an `awk` script to iterate over the string and sort it?
