bash - Variables from file -

-

a text file has following structure:

paa pee pii poo puu baa bee bii boo buu gaa gee gii goo guu maa mee mii moo muu

reading line line in script done 

while read line;      action done < file

i'd need parameters 3 , 4 of each line variables action. if manual input, $3 , $4 trick. assume awk tool, can't wrap head around syntax. halp?

read fine. pass multiple variables , split on $ifs many fields.

while read -r 1 2 3 4 five;     action "$three" "$four" done <file

i added -r option because want. default behavior legacy oddity of limited use.

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

-
