Fix software with awful budget cut (5)
I believe the answer is:
debug
'fix software with' is the definition.
I can't judge whether this definition defines the answer.
'awful budget cut' is the wordplay.
'awful' indicates anagramming the letters.
'cut' means to remove the last letter.
'budget' with its last letter removed is 'budge'.
'budge' with letters rearranged gives 'DEBUG'.
Can you help me to learn more?
(Other definitions for debug that I've seen before include "Remove errors from a computer program" , "Refrain (from)" , "Fix (program) errors" , "Correct defect in computer program" , "put things right" .)
