bash - cat/column 环境下一行打印文件

Question

我需要在 cat/column 环境中的一行中打印文件列表。问题是——它打印成多行：

#!/bin/bash

Files=`ls ~/`

echo $Files # prints in one line as I want. But I have to do it inside cat/column:

# prints files in column -- despite column separator is &:
cat << EO | column -s\& -t

$Files

EO

Answer 1

您可以在没有以下情况下达到相同的效果cat：

echo $Files | column -s\& -t

这不会给出问题cat。

对于链接中给出的输入：

    column -s\& -t <(echo "  -a, --all & apply the sed script to files in current dir and subdirs
-d, --dirs & apply the sed script to first-level-dir names
-f, --file & apply the sed script to a given file. It is a single command, but the script keep You from getting into manuals
-h, --help & show this output
-s, --script & the sed script to be used (currently: `ls $(dirname $0)/scripts`)
-v, --version & show version information
-I, --noi & overwrite existing files")

会工作。
