Awk: subset of fields as variable with sprint
Dear Unix Gurus,

input:
Code:
A|1|2|3|4|5
B|1|2|3|4|3
C|1|2|3|4|1
D|1|9|3|4|12

output:
Code:
A_(5);B(3);C(1)|1|2|3|4
D_(12)|1|9|3|4

Details:
If $2, $3, $3, $5 are identical, concatenate $1 and associated $NF together in the first field.
But I am trying to do the above by passing the identical fields to a sprintf variable.

With my code below, sprintf variable write all the fields on a new line, so I assume it comes from the for loop in the main block, but I don't see what is wrong:
Code:
gawk 'BEGIN{FS=OFS="|"; start=2; end=5}{for(i=start; i<=end; i++){var=sprintf("%s%s",$i, i<e ? OFS : "\n")}; common[var] = common[var] (common[var]? ";" : "") $1"_("$NF")"}END{for(j in common){print common[j] OFS j}}' input
