Question

我可以在使用单个命令创建文件/目录时设置权限，还是必须先创建文件/目录然后使用chmod设置其权限？

例如做这样的事情

// for directories
mkdir 755 test 

// for files
touch 644 test/my_file.php

Answer 1

手册页是你的朋友。这可以使用GNU mkdir但不能使用GNU touch。

mkdir -m 755 test

Answer 2

对于文件，请尝试使用WITH t4 AS (SELECT n FROM (VALUES(0),(0),(0),(0)) t(n)) ,t256 AS (SELECT 0 AS n FROM t4 AS a CROSS JOIN t4 AS b CROSS JOIN t4 AS c CROSS JOIN t4 AS d) ,t16M AS (SELECT ROW_NUMBER() OVER (ORDER BY (a.n)) AS num FROM t256 AS a CROSS JOIN t256 AS b CROSS JOIN t256 AS c) SELECT DATEADD(day, CAST(CAST(NEWID() AS varbinary(1)) AS int) % 3, '20150103') AS Date ,DATEADD(millisecond, CAST(CAST(NEWID() AS varbinary(4)) AS int), CAST('' AS time)) AS Time ,(CAST(CAST(NEWID() AS varbinary(3)) AS int) % 900) + 100 AS [Sum] ,(CAST(CAST(NEWID() AS varbinary(3)) AS int) % 2) + 1 AS TypeID ,(CAST(CAST(NEWID() AS varbinary(3)) AS int) % 10) + 1 AS PlaceID ,(CAST(CAST(NEWID() AS varbinary(3)) AS int) % 3) + 1 AS StatisID FROM t16M WHERE num <= 10000;命令：

install

对于文件夹，$ install -m 644 /test/path/ myfile.php mkdir参数：

-m

您可能必须将其作为$ mkdir -m 755 test执行。

您可以使用以下命令创建目录并同时授予权限

mkdir -m755 test
