英文:
bash: filename with space gets truncated
问题
#!/bin/bash
documents=("/datalog/AB errors.txt");
/usr/bin/bash /home/user/download.sh "${documents[*]}";
download.sh会SCP到服务器并下载documents，但在上面的情况下，文件名中有空格，这会导致它寻找/datalog/AB而不是AB errors.txt文件。
我认为用双引号括起来可以解决文件名中的空格问题。我还尝试过AB\ errors.txt，但这导致整个bash脚本都无法运行。
英文:
#!/bin/bash
documents=("/datalog/AB errors.txt");
/usr/bin/bash /home/user/download.sh "${documents[*]}"
the download.sh SCPs into a server and downloads documents but in the case above there is a space in the file name which leads it to seek /datalog/AB instead of AB errors.txt file.
I thought surrounding in double quotes fixes the space in filename issue. I also tried AB\ errors.txt but that caused the entire bash script to not run.

以下是已翻译的内容：
表单
documents="/datalog/AB errors.txt"
是不好的形式（将字符串转换为数组!!!）。 赋值的正确形式是
documents="/datalog/AB errors.txt"
始终假定完整路径变量可能包含空格或其他字符，并始终对此类变量实例进行双引号引用，即
ls "${variable}" .
正如Gordon Davisson所说，您必须在脚本/编程的每个层面以这种方式编写代码，以确保嵌入的特殊字符不会导致意外结果。
英文:
The form
documents=("/datalog/AB errors.txt")
is bad form (turning string into an array !!!). The correct form for assignment is
documents="/datalog/AB errors.txt"
Always assume full-path variables can have spaces or other characters, and always double-quote such variable instantiations, i.e.
ls "${variable}" .
As Gordon Davisson said, you must code in this fashion at every level of scripting/programming to ensure the embedded special characters don't lead to unexpected results.
