在list...how中的每个路径上运行命令来执行循环吗？
在list...how中的每个路径上运行命令来执行循环吗？

我们需要将目标文件夹的列表设置为777。
请告诉我，这类循环有一个更干净、更聪明的方法，而不必吐出一个文件，然后从文件中读取。:)

可以将所有文件转储到数组中：
arr=("file1" "file2" "file3")
chmod -- 777 "${arr[@]}"如果您有大量的文件，您可能会遇到Argument list too long错误。在这种情况下，您可以这样做：
printf '%s\0' "${arr[@]}" | xargs -0 chmod -- 777或者使用一个好的旧for循环：
for file in "${arr[@]}"; do
chmod -- 777 "$file"
done当然，您可以直接遍历文件：
for file in "file1" "file2" "file3"; do
chmod -- 777 "$file"
