Learning morse code from a shell script

[EDIT] This was recovered due to a massive db crash and losing a couple of years worth of articles. Dates are mismatching. [EDIT]

Hey all,
As i am learning to understand morse i decided to write a shell script that would help you learn also.
Why in shell script ?
why not.

Here is the script. It is called “ceedubs” (cw. get it ?)

It requires:
– SoX for the play utility.

It will do:
– multiple words
– dictionary words
– mixed letters and numbers
– just numbers
– will display each letter / number and its morse equivalent
– will play the tones dits & dahs of each character
