Hello gpk_newbie,

Following may help you to understand the command.
Code:
awk -F,                           ########### Making comma(,) as a field seprator.
'{gsub(/..../,"&-",$4);           ########### using global subtitutaion to change any 4 chars/digits etc to their value with - by using (&-) in $4 as per your request
sub(/\-$/,X,$4);}                 ########### When we use global subtitutaion then it will place - at last of the string then I am removing it by sub which means only single time subtitutaion, That's the difference between global subtitutaion and single substitutaion in awk.
1' OFS=,  Input_file              ########### awk works on condition and then action, if condition is TRUE following action mentioned in it will be performed. So here I am making comndition TRUE by mentioning 1 and no action mentoined so awk will take default action which is print so it will print the complete line then.

Thanks,
R. Singh
