awk的問(wèn)題

boy1006

cat command
[b]awk '$1=="girl001" {boy+=$2} END {print boy"\tgirl001"}'
awk '$1=="girl002" {boy+=$2} END {print boy"\tgirl002"}'
awk '$1=="girl003" {boy+=$2} END {print boy"\tgirl003"}'[/b]
可以把三行類似滴指令，寫(xiě)在一起嗎

john_student

是可以的。

[b]請(qǐng)教各位大大[/b]
那應(yīng)該要怎麼寫(xiě)呀？

AD版主GG的AWK玩得牛,問(wèn)問(wèn)他吧~,

bjgirl

實(shí)在不會(huì)用AWK的循環(huán),唉~~,來(lái)個(gè)愚蠢點(diǎn)的吧

2. #!/bin/ksh
3. n=1
4. m=$(grep girl<urfile|cut -f1 -d" "|sort|uniq -d|wc -l)
5. while ((n<=$m));do
6.         grep girl00$n<urfile|awk '{boy+=$2}END{print\ boy,"\t"$1}'
7.         ((n+=1))
8. done

復(fù)制代碼

效率實(shí)在太低

   print boy1, "\tgirl001\n"..........

是不是得用個(gè)計(jì)數(shù)器呀?,因?yàn)間irl的數(shù)目要遠(yuǎn)遠(yuǎn)超過(guò)3個(gè)呢...關(guān)注中...

如果想加的while怎麼加呀？
while read girl
  do
    XXXX{寫(xiě)不出來(lái) >_<}
done < girl_file
