因此,我试图检查是否存在档案,而如果是这样的话,那么该书本应做些什么。问题Im实际上正在得到承认,实际上就是这样。

if [ -e /temp/file.txt ]; then
        echo "file found!"
        sudo cp -r temp/* extra
else
        echo "file not found! Creating new one..."
        ./create.sh
fi

下面是Im检测中文档的例子。他们显然在那里,但出于某种原因,我只能拿到文字来看到这一点。我做了什么错误?

nima@mkt:/docs/text$ ls -a temp
.  ..  more  file.txt  file2.txt
