[SOLVED] How to convert numbers to the first letters of the alphabet?

Issue

I have a file with content like

12345

I need to convert this kind of strings like this:

"0"->"a"
"1"->"b"
...
"9"->"j"

So, 12345 should result in abcde. I want to achieve this via the shell (bash). What is the best way to do this?

Solution

In any shell, you could use:

echo "$string" | tr 0123456789 abcdefghij

Or, in Bash and without a pipe:

tr 0123456789 abcdefghij <<< "$string"

(where the double quotes might not be necessary, but I'd use them to be sure).
