如何在Bash中对齐以空格分隔的表的列? [英] How can I align the columns of a space separated table in Bash?

问题描述

我有一个文件，其中有任意数量的非对齐列，用空格分隔.

I have a file with an arbitrary number of non-aligned columns separated with whitespace.

我想对齐文件的列.

我看过col命令，它似乎不合适.

I've looked at the col command, and it doesn't seem appropriate.

我可以编写一个 AWK 脚本，但似乎应该存在一个更明显的命令

I could write an AWK script, but it seems like a more obvious command should exist.

推荐答案

您可能希望column命令(通常与--table / -t一起使用)产生基本的表格输出:

You might want the column command, usually with --table / -t to produce basic tabular output:

在手册页中:

 -t, --table 

确定输入包含的列数并创建一个表.默认情况下，列用空格定界，或使用--output-separator选项提供的字符定界.表输出对于漂亮打印很有用.

Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the charac‐ters supplied using the --output-separator option. Table output is useful for pretty-printing.

column -t [file]

# or from stdin
cat file | column -t

# For a quick demonstration, format the output of mount
mount | column -t

column还有很多其他复杂的选项. man column了解详情.

column has a lot of other complex options. man column for details.
