AWK 實例

Eg 1

111 2 11111
123 1 13341
122 2 11322
.......

切割后:
根据$2分类..
文件1.
111 1 11111
122 1 11342
文件2.
111 2 11111
122 2 11111
123 2 11111
文件3.........

我自己贴吧
for i in `ls $path`
for k in 1 2 3 4 5 6 7 8
do
awk { if ($2=='"$k"') print $0}' $path/$i >> $path/$k.DAT
done
done

或:

awk '{if ($2==1)print $0}' file >file1
awk '{if ($2==2)print $0}' file >file2
.......

Eg 2

cat file

处理后：
awk '{a1=substr($1,1,3);a2=substr($1,4,3);a3=substr($1,7,3);a4=substr($1,10,4);a5=substr($1,14);print a1,a2,a3,a4,a5,$2}' file
