我怎样才能格式化bash命令的整齐的列输出 [英] How can I format the output of a bash command in neat columns

问题描述

我有输出的多行信息，我想在列格式化的功能。问题是数据的任何特定的细胞（如果我可以用这个词）的宽度是可变的，所以管道为类似awk并没有给我我想要的东西。

I have a function which outputs many rows of information which I want to format in columns. The problem is that the width of any particular "cell" (if I may use that term) of data is variable, so piping it to something like awk does not give me what I want.

功能是钥匙（这不是问题），我想是这样的：

The function is "keys" (not that it matters) and I'm trying something like this:

$ keys | awk '{ print $1"\t\t" $2 }'

但输出（它的一个片段，那是）是这样的：

but the output (a snippet of it, that is) looks like this:

"option-y"      yank-pop
"option-z"      execute-last-named-cmd
"option-|"      vi-goto-column
"option-~"      _bash_complete-word
"option-control-?"      backward-kill-word
"control-_"     undo
"control-?"     backward-delete-char

我怎么能强迫的东西留在整齐的列？这是可能使用awk，或者我需要用别的东西吗？

How can I force things to stay in neat columns? Is this possible with awk, or do I need to use something else?

推荐答案

列（1） 是你的朋友。

column(1) is your friend.

$ column -t <<< '"option-y"      yank-pop
> "option-z"      execute-last-named-cmd
> "option-|"      vi-goto-column
> "option-~"      _bash_complete-word
> "option-control-?"      backward-kill-word
> "control-_"     undo
> "control-?"     backward-delete-char
> '
"option-y"          yank-pop
"option-z"          execute-last-named-cmd
"option-|"          vi-goto-column
"option-~"          _bash_complete-word
"option-control-?"  backward-kill-word
"control-_"         undo
"control-?"         backward-delete-char
