Bash 如何删除'$'\n'；附加到ldd列表的字符

我试图将二进制依赖项复制到其他文件夹，因此我使用

ldd

查看应该复制什么

但是，复制时脚本失败。复制二进制依赖项时，它“显示”

“$”\n“

个字符

有点不对劲，但我不知道是什么。已尝试按命令运行命令，但看不到故障

这里有什么问题

谢谢

脚本代码 脚本输出

我使用此脚本的目的是：

copydep.sh

按如下方式运行：

$ mkdir /tmp/test
$ bash copydep.sh /bin/ls /tmp/test
---> copy binary itself
/bin -> /tmp/test/bin
'/bin/ls' -> '/tmp/test/bin/ls'
---> copy libraries
/lib -> /tmp/test/lib
/lib/x86_64-linux-gnu -> /tmp/test/lib/x86_64-linux-gnu

deps

变量应该是一个数组，使用以下内容创建并重定向：
