檔案 rectData.ssv 包含:
rectangle1;1;2
rectangle2;1;10
rect4;10;10
如何更改以下命令以對齊列:
$ awk -F ";" '{ print "area of", $1,":", $2 * $3}' rectData.ssv
area of rectangle1 : 2
area of rectangle2 : 10
area of rect4 : 100
預期輸出如下:
area of rectangle1: 2
area of rectangle2: 10
area of rect4: 100
(2、10 和 100 左對齊)
或者:
area of rectangle1: 2
area of rectangle2: 10
area of rect4: 100
(2、10 和 100 右對齊)
另外,如何在末尾添加一行總計(2、10、100 和 112 右對齊):
area of rectangle1: 2
area of rectangle2: 10
area of rect4: 100
TOTAL AREA: 112
答案1
嘗試對您的嘗試進行以下調整:
$ awk -F ";" '
{TOT += $2 * $3
printf "area of %s: %*d\n", $1, 14-length($1), $2 * $3
}
END {printf "TOTAL AREA: %*d\n", 12, TOT
}
' file
area of rectangle1: 2
area of rectangle2: 10
area of rect4: 100
TOTAL AREA: 112
答案2
$ awk -F ';' -v OFS='\t' '
{ tot+=prod=$2*$3; print "area of " $1 ":", prod }
END { print "TOTAL AREA:", tot+0 }
' file | column -s$'\t' -t
area of rectangle1: 2
area of rectangle2: 10
area of rect4: 100
TOTAL AREA: 112
