1，#! /bin/awk -f
！用來定義解釋性語言使用的解釋器
2惭笑，檢索特定字符串，并輸出
awk '/li/ { print $0 }' mail-list
3， 獲取行數(shù)最多的一行
awk '{ if (length($0) > max) max = length($0) }
END { print max }' data
4沉噩， 獲取行field多余0的數(shù)據(jù)
awk 'NF > 0' data
5捺宗，獲取一個文件夾中的文件大小總和
ls -l files | awk '{ x += $5 }
END { print "total bytes: " x }'
6，計算總行數(shù)
awk 'END { print NR }' data
7川蒙，默認不支持多行蚜厉，但是可以通過反斜線連接
awk '/This regular expression is too long, so continue it
on the next line/ { print $1 }'
8，對某個field進行正則匹配
awk '$1 ~ /J/' inventory-shipped
附錄數(shù)據(jù)：
