Apologies, probably didn't explain as well as I could have.
There is effectively no output. What I want to happen is where there is a count match for a pair of letters in each file, I want this to then trigger a command.
So basically with the example provided in this instance only CC would match as both have a count of 3 (and therefore trigger command). The remaining letter pairs wouldn't trigger my command as the counts in each files do not match.
Does this clarify?

alter_trigger
ALTER
TRIGGER(7) PostgreSQL 9.2.7 Documentation ALTER TRIGGER(7)
NAME
ALTER_TRIGGER - change the definition of a trigger
SYNOPSIS
ALTER TRIGGER name ON table_name RENAME TO new_name
DESCRIPTION
ALTER TRIGGER changes properties of an existing trigger. The RENAME clause changes the name of the given trigger without otherwise changing
the trigger definition.
You must own the table on which the trigger acts to be allowed to change its properties.
PARAMETERS
name
The name of an existing trigger to alter.
table_name
The name of the table on which this trigger acts.
new_name
The new name for the trigger.
NOTES
The ability to temporarily enable or disable a trigger is provided by ALTER TABLE (ALTER_TABLE(7)), not by ALTER TRIGGER, because ALTER
TRIGGER has no convenient way to express the option of enabling or disabling all of a table's triggers at once.
EXAMPLES
To rename an existing trigger:
ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;
COMPATIBILITY
ALTER TRIGGER is a PostgreSQL extension of the SQL standard.
