How can I align the columns of a space separated table in Bash?
提问by Richard
I have a file with an arbitrary number of non-aligned columns separated with whitespace.
我有一个文件，其中包含任意数量的用空格分隔的非对齐列。
I would like to align the columns of the file.
我想对齐文件的列。
I've looked at the colcommand, and it doesn't seem appropriate.
我查看了col命令，它似乎不合适。
I could write an AWKscript, but it seems like a more obvious command should exist.
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。

You might want the columncommand, usually with --table / -tto produce basic tabular output:
您可能需要该column命令，通常--table / -t用于生成基本的表格输出：
From the man page:
从手册页：
-t, --tableDetermine 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.
-t, --table确定输入包含的列数并创建一个表。默认情况下，列以空格或使用 --output-separator 选项提供的字符分隔。表格输出对于漂亮的打印很有用。
column -t [file]
# or from stdin
cat file | column -t
# For a quick demonstration, format the output of mount
mount | column -t
columnhas a lot of other complex options. man columnfor details.
column有很多其他复杂的选择。man column详情。
