将输入数据组织为 3D 配置
原标题:Organize input data as a 3D configuration

我从“file.txt”输入的数据如下(摘录样本):

245.214
188.936
195.758
194.939
194.242
188.936
  ...

然而,我使用的软件要求将数据组织成3D配置

245.214 188.936 195.758
194.939 194.242 188.936
....

我用Ubuntu Linux(Ubuntu Linux)转换输入数据最简单的方式是什么?

最佳回答

我可以用这个代码获得所需的输出

awk  {if(NR%3 == 0){printf("%s
",$0);}else{printf("%s ",$0);}}  ip_file.txt
问题回答

您可以使用 ", http://www.manpagez.com/man/1/column/" rel="nofollow" > column 命令 :

cat file.txt | column -c 28 -s " "
$ xargs -n3 < file.txt mycommand

或者,如果在另一个文本文件中需要:

$ xargs -n3 < file.txt > foo.txt

使用纯巴什 :

printf  %7.3f %7.3f %7.3f
  $(<file.txt)
