我有这个代码。我想在上述代码中添加一个参数（机场名称）。所以，给定一个机场的名称，我会得到相同的输出，但仅限于给定的参数。
代码：
获取一周中每一天的延误航班百分比、延误航班总数和航班总数。
BEGIN { FS = OFS = "," }
FNR > 1 {
total[$2]++; if ($6) delay[$2]++ }
END {
print "\"weekday\"", "\"percentage_delayed\"", "\"delayed\"", "\"total_flights\""
for (day in total) { print day, delay[day] / total[day] * 100, delay[day], total[day]}
}
输入：
第 3 列和第 4 列是机场名称。
"DAY_OF_MONTH","DAY_OF_WEEK","ORIGIN","DEST","DEP_TIME","DEP_DEL15","CANCELLED","DIVERTED","DISTANCE"
1,Tuesday,ORD,GRB,1003,0.00,0.00,0.00,322.248
1,Tuesday,TUL,ORD,1027,0.00,0.00,0.00,1083.42
1,Tuesday,EWR,TYS,1848,0.00,0.00,0.00,1168.61
输出：
"weekday", "percentage_delayed", "delayed", "total_flights"
Tuesday,10.7912,446,4133
Moday,10.2564,336,3276
Friday,26.6401,735,2759
如何向代码中添加参数，使其仅显示给定参数的输出？
谢谢
