使用列命令的 Bash 错误:“列:行太长" [英] Bash error using the column command: 'column: line too long'

问题描述

当我在输入文件中输入此列命令时，出现以下错误

When I type this column command with my input file I get the following error

column -t text.txt > output
column: line too long
column: line too long
column: line too long
column: line too long
column: line too long
column: line too long

当我查看文件输出时，似乎没有打印文件的前半部分(从左到右).

When I look at the file output it seems that the first half of the file(from left to right) is not printed.

有没有办法解决这个错误?有没有办法在没有这个错误的情况下完全按照命令执行的操作?

Is there a way around this error? Is there a way to do exactly what the command would do otherwise without this error?

样本输入(真实输入 ~640 列)

Sample input (Real input ~640 columns)

column1 column2 column3 column4
03  2   45  3
5   6   7   8

样本输出(实际输出 ~640 列)

Sample output (Real output ~640 columns)

column1    column2  column3  column4
03         2        45       3
5          6        7        8

推荐答案

你可以尝试一个简单的 awk 实现:

You could try a naive awk implementation:

awk 'NR==FNR{for(i=1;i<=NF;i++) 
        max[i] = length($i) > max[i] ? length($i) : max[i]; next} 
{ for(i=1;i<=NF;i++) printf "%-"max[i]"s  ", $i; printf "\n"}' text.txt text.txt
