Question

我有一个包含两列的文件：

73697695 1111111100110100211010101100000110100111  
73697715 0100001010100022000020000000000200200000  
73698148  0000000000200000000200220001100100010111  
73698210 1111111211011012001011000001111000001110  
73698229 1111111100110111110020101000000111210011  
736985237658373533  0000000110100011101010000001100100100000  
73698858 1111111210010011101010000001100100100111  
73698887 2222222200020000202000000010001100110000  
73699163 2222222200020100110110211100000100100100  
7369929986423  2222222200020100110110211100000011110111

我正在尝试创建一个bash文件来格式化其列。首先，我需要找到第一列的最大长度。所以，我这样做了：

lengthID=$(awk '{ if (length($1) > max) max = length($1) } END { print max }' file)

之后我想申请＃34; lengthID＆＃34;到这样的文件，根据＆＃34; lengthID＆＃34;将第一列对齐到右边。第二列必须与左侧对齐。我尝试使用以下命令行，但它不起作用。

awk '{printf("%"lengthID"s%1s%" "s\n",$1," ",$2)}' file > temp && mv temp file

我知道最大长度是18（lengthID = 18）。因此，以下命令将起作用：

awk '{printf("%18s%1s%" "s\n",$1," ",$2)}' file > temp && mv temp file

我会得到这样的文件（正是我需要的）。但是，我想自动找到这样的长度并使用它。

有没有人知道这样做的方法？

谢谢。

你确定不能只使用column -t file吗？

$ column -t file

对齐方式不同，但如果您只需要视觉列，那可能就行了。

使用printf格式化两列宽度
