私のファイルには、複数のヘッダーと複数のレコードタイプ（例：0001、0002、0003、0004）があります。テール行の各レコードタイプの数は、完全な詳細レコードの数とともに提供されます。

ファイルの詳細：
Detail records are where 1 to 4 position data in (0001, 0002, 0003, 0004)
Trailer:
Trailer identifier(position 1 to 4) = T999
total data count (position 5 to 7) = 008
count of record type 0001 (position 8 to 10) = 002
count of record type 0002 (position 11 to 13) = 002
count of record type 0003 (position 14 to 16) = 004
count of record type 0004 (position 17 to 19) = 001
必要：
-- Compare overall detail row count where 1 to 4 position data in (0001, 0002, 0003, 0004) with trailer record count (position 5 to 7)
-- Compare each Record type row count with trailer record count
eg. Compare row count where 1 to 4 position data = 0001 with trailer record count for 0001 (position 5 to 7)
.....
-- Stop execution in case of detail record row count and trailer count mismatch
予想出力：
Overall detail row count 8 matches with trailer record count 8.
Row count for 0001 record type 2 matches with trailer record count 2.
Row count for 0002 record type 2 matches with trailer record count 2.
Row count for 0003 record type 3 does not match with trailer record count 4.
Stopping execution.

使用アッ:
awk '/^000[1-4]/{ rec[substr($0, 1, 4)+0]++; totalRec++ }
END{ trailTotalRec=substr($0, 5, 3)+0
for(i=1; i<=4; i++) { trailRec[i]=substr($0, pos+8, 3)+0; pos+=3 }
if(trailTotalRec==totalRec)
print "Overall detail row count", totalRec, "matches with trailer record count", trailTotalRec"."
for(i=1; i<=4; i++) {
print "Row count for 000" i, "record type", rec[i], (trailRec[i]==rec[i]?"matches":"does not"), "with trailer record count", trailRec[i]"."
if(trailRec[i]!=rec[i]) { print "Stopping execution."; exit 7 }
}
