How to create a directory in Lua?

问题 Is it possible to create a directory in lua ? If so, how ? 回答1: There's a "system" call (or something like that, this is from memory) which you should be able to use to run an arbitrary program, which could include the mkdir command. EDIT: I found my Programming in Lua book. On page 203, it mentions how you could use an os.execute("mkdir " .. dirname) to "fake" a directory creation command. EDIT 2: Take note of Jonas Thiem's warning that this command can be abused if the directory name comes

由 走远了吗. 提交于 2020-01-12 12:50:48
问题 I'm trying to move a folder by renaming it. Both the test1 and test2 folders already exist. rename( "test1", "test2/xxx1/xxx2" ); The error I get is: rename(...): No such file or directory I assume this is because the directory "xxx1" does not exist. How can I move the test1 directory anyway? 回答1: You might need to create the directory it is going into, e.g. $toName = "test2/xxx1/xxx2"; if (!is_dir(dirname($toName))) { mkdir(dirname($toName), 0777, true); } rename("test1", $toName); The third

嵌入式Linux往往没有用户管理，shell登陆也仅仅是给开发者用的。因此，像Android，无需输入用户名，可以直接登入shell。如果你需要用户管理（嵌入式Linux通常只需要root），可以添加/etc/passwd。login shell读取输入的用户名和密码后，在passwd文件中验证输入的合法性。 添加passwd前，必须了解passwd的格式。 The /etc/passwd contains one entry per line for each user (or user account) of the system. All fields are separated by a colon (:) symbol. Total seven fields as follows. Generally, passwd file entry looks as follows (click to enlarge image): (Fig.01: /etc/passwd file format - click to enlarge) Username : It is used when user logs in. It should be between 1 and 32 characters in length. Password : An x character

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I have a tree of directories, sub-directories, and files (in some but not all the directories). Here's an example of the whole tree: /food /food/drinks /food/drinks/water.html /food/drinks/milk.html /food/drinks/soda.html /food/entrees /food/entrees/hot /food/entrees/hot/hamburger

Using `read` system call on a directory

由 旧巷老猫 提交于 2020-01-11 09:52:32
问题 I was looking at an example in K&R 2 (8.6 Example - Listing Directories). It is a stripped down version of Linux command ls or Windows' dir . The example shows an implementation of functions like opendir , readdir . I've tried and typed the code word-by-word but it still doesn't work. All it does is that it prints the a dot (for the current directory) and exits. One interesting thing I found in the code (in the implementation of readdir ) was that it was calling the system calls like open and
