I have to write a script for an assignment which will take the file name as a command and output every unique 3 base codon in the file and how many times it occurs in descending order. The script has to check it has an argument and if not output an error message. Im confused as to how to begin thee and the syntax for the regular expression which I will need to have the script search for each unique codon.
