我希望使用AWK(Windows)将一个具有单列的文本文件转换为多列-count在脚本或命令行中指定。 这个问题以前有人问过,但我的最终数据文件需要始终具有相同的列计数。 输入示例: L1 L2 L3 L4 L5 L6 L7 分成3列,“;”作为分隔符 L1;L2;L3 L4;L5;L6
All that allows you to write compact programs to perform calculations on data columns: awk '{ SUM=SUM+$1 } END { print SUM }' FS=, OFS=, file 263 Or, equivalently using the += shorthand syntax: awk '{ SUM+=$1 } END { print SUM }' FS=, OFS=, file 263 Please note AWK ...
将n截断为2位小数的一些方法如下: n = substr(n,1,match(n,/[.]/)+2)n = sprintf("%0.2f",n) 因此,您的脚本可以是: BEGIN { FS=OFS="," } # delimit columns by comma # csv must not have embedded commasNR==1 {print; next} # print header{ $10 = sprintf("%0.2f", $10) } ...
