如何在同一行上打印bash数组 [英] How to print a bash array on the same line

问题描述

我正在将文件类型数据读入bash数组中，并且需要将其内容打印在同一行中并带有空格.

I am reading in filetype data into a bash array and need to print its contents out on the same line with spaces.

#!/bin/bash

filename=$1
declare -a myArray

readarray myArray < $1

echo "${myArray[@]}" 

我尝试这样做，即使使用echo -n标志，它仍然会打印在换行符上，我还缺少什么，printf会更好地工作吗?

I try this and even with the echo -n flag it still prints on newlines, what am I missing, would printf work better?

推荐答案

readarray在每个数组元素中保留尾随换行符.要删除它们，请使用-t选项.

readarray retains the trailing newline in each array element. To strip them, use the -t option.

readarray -t myArray < "$1"
