Delete files which has the same prefix

$prefix = 'something_prefix'; unlink($prefix.'.*'); the code above is not working, but I see some code like this below works just fine unlink('*.jpg'); why? I am wonder is this going to work? unlink('*.*'); how to delete the files which they begin with the same string? like this same123.jpg sametoo.png samexxx.gif they all begins with the string "same" but ends with different extension, how to do this? I alread have a cheap way to do this, but I wonder if there is any better solution? Try this code: $mask = 'your_prefix_*.*'; array_map('unlink', glob($mask)); p.s. glob() requires PHP 4.3.0+

问题 I would like to delete a file that is found in my localhost. localhost/project/folder/file_to_delete I'm using codeigniter for this. I would like to use the unlink() function in php but I really can't understand how to use it. 回答1: you can use the "file helper" in codeigniter. http://codeigniter.com/user_guide/helpers/file_helper.html and like this : $this->load->helper("file"); delete_files($path); Late Edit: delete_files method uses a path to wipe out all of its contents via unlink() and

Change read/write permissions on a file descriptor

由 跟風遠走 提交于 2019-11-29 09:49:56
I'm working on a linux C project and I'm having trouble working with file descriptors. I have an orphan file descriptor (the file was open()'d then unlink()'d but the fd is still good) that has write-only permission. The original backing file had full permissions (created with S_IRUSR | S_IWUSR | S_IRGRP | S_IROTH), but alas the file was opened with O_WRONLY. Is it possible to duplicate the file descriptor and change the copy to O_RDWR? psudo-code: //open orphan file int fd = open(fname, O_WRONLY, ...) unlink(fname) //fd is still good, but I can't read from it //... //I want to be able to read

后端也可以亲自使用IDEA调试angular代码

有时间为了一个问题，需要来来回回跟前端同事联合调试了好多次，既浪费时间，又耽误了前端的进度，OK，为了节省大家的时间，我们自己开动吧！ 安装nodejs 官网（https://nodejs.org/zh-cn/）下载安装包，安装完成后，配置环境变量： path=D:\Program Files\nodejs\ 在CMD测试安装是否完成： npm r-version 6.5.0-next.0 下载angular源码 得到源码之后，IDEA直接file - open既可打开angular项目，找到项目根目录下的package.json，这相当于java项目的pom.xml，里面配置好了编译、运行这个项目的命令： 笔者试着运行build，系统提示识别不了“ng”命令。 打开terminal，运行 npm install -g @angular/cli ，进行依赖的安装，出现了很多ERR： $ npm install npm WARN tarball tarball data for echarts@4.2.0-rc.2 (sha1-apg5eq+oG2XL8LwV2a/b+yRN+R4=) seems to be corrupted.

Delete files with special characters in filenames

由 时间秒杀一切 提交于 2019-11-28 14:07:06
I need to delete old files with special characters in filenames like space, , , ( , ) , ! and so on via PHP. Classic unlink($filename) does not work for these files. How can I transform filenames to filenames which accepts unlink function and filesystem? It's running on a Solaris machine and I don't have another access to it. How are you constructing the $filename ? unlink should work on any filename with special characters if you do the normal escaping on it. e.g. for a file with a name of this has, various/wonky !characters in it , then $filename = 'this has\, various\/wonky \!characters in

PHP: Unlink All Files Within A Directory, and then Deleting That Directory

由 耗尽温柔 提交于 2019-11-28 05:47:28
I there a way I can use RegExp or Wildcard searches to quickly delete all files within a folder, and then remove that folder in PHP, WITHOUT using the "exec" command? My server does not give me authorization to use that command. A simple loop of some kind would suffice. I need something that would accomplish the logic behind the following statement, but obviously, would be valid: $dir = "/home/dir" unlink($dir . "/*"); # "*" being a match for all strings rmdir($dir); Lusitanian Use glob to find all files matching a pattern. function recursiveRemoveDirectory($directory) { foreach(glob("{

Redis 4.0鲜为人知的功能将加速您的应用程序

由 荒凉一梦 提交于 2019-11-28 00:53:32
来源：Redislabs 作者：Kyle Davis 翻译：Kevin (公众号：中间件小哥） Redis 4.0给Redis生态带来了一个惊人的功能：Modules（模块）。Modules是Redis的一大转变，它是Redis内部自定义数据类型和全速计算的开放环境。但是，尽管对该版本的大多数关注都集中在Modules上，但 新版本还引入了一个非常重要的命令，它就是游戏规则的改变者：UNLINK。 您可以使用redis-cli连接redis-server执行info命令，去查看当前redis版本中是否可以使用UNLINK命令。info响应将告诉您有关服务器的所有信息。在第一部分（#Server）中，返回结果有一行值为redis_version。如果该值大于4.0，则可以使用UNLINK命令。并非所有Redis提供商都保持最新版本，因此最好在更改代码之前检查redis版本。 让我们回顾一下Redis的关键架构功能之一：“单线程”。Redis在大多数情况下是一个单线程应用程序。它一次只做一件事，这样可以把这些事做的更快。多线程有点复杂，并且引入了锁和其他可能降低应用程序速度的问题。尽管Redis（最高4.0版）通过多线程方式执行了少量操作，但它通常在启动另一个命令之前先要完成一个命令。 相比于快速读写，您可能会觉得使用DEL命令去删除一个键值不需要考虑太多，但是在很多情况下

Git - Unlink of file .idx and .pack failed (The only process owned handle to this file is git.exe)

Please, look at this picture! could be git that stupid? Git couldn't unlink some file, but only git.exe is holding a handle to this file.

My Git version is 1.9.5-preview20141217 Git 2.19 (Q3 2018) improves the file descriptors management for the packfiles, and avoid the " Unlink of file... failed. Should I try again? " error message.
