问题 How is the Best and fastest way to do it? 回答1: PowerShell: $f = new-object System.IO.FileStream c:\temp\test.dat, Create, ReadWrite $f.SetLength(42MB) $f.Close() This will create a file c:\temp\test.dat that consists of 42MB of nullbytes. You can of course just give byte count instead as well. (42MB = 42 * 1048576 for PowerShell) 回答2: I found this Page, I try it and work great. To create a single File use fsutil file createnew filename filesize To create a lot of Files use For /L %i in (1,1

问题 I am running ES locally and have defined path.data in my home dir aka /Users/prerna/es/data but all the time ES complains that high-disk watermark exceeded as shown in below message 2020-09-16 18:16:07,390][INFO ][cluster.routing.allocation.decider] [Karkas] high disk watermark exceeded on one or more nodes, rerouting shards [2020-09-16 18:16:37,393][WARN ][cluster.routing.allocation.decider] [Karkas] high disk watermark [0b] exceeded on [trwvlC3dRUOPYp0QQ9l9GQ][Karkas] free: -1b[100%],

问题 The problem. I have a problem with some Java daemon simply copying files from one directory into another in theory, but under some setups those directories are provided as network shares of some Windows Server 2016. Under some circumstances it occasionally happens that copying fails because of Java throwing an IOException during trying to canonicalize paths and I'm somewhat sure that this happens because during that operation FindFirstFileW is used. If a file is not found, that simply fails

问题 I'm running two processes on AIX. Process one is generating several files, process two does backups from all files that are in a backup directory. Process one will copy or move the files into the backup directory. Since process two is always running in the background there is the risk of it starting a backup of a file that is still in the process of being copied or moved and therefore incomplete. How can I avoid this problem? 回答1: Process one should create files in another directory (on the

问题 Could someone provide (or point me to a list) of all the illegal characters in the XFS filesystem? I'm writing an app that needs to sanitize filenames. EDIT: Okay, so POSIX filesystems should allow all characters except the NUL character, forward slash, and the '.' and '..' filenames are reserved. All other exceptions are application-level. Thanks! 回答1: POSIX filesystems (including XFS) allow every character in file names, with the exception of NUL (0x00) and forward-slash (/; 0x2f). NUL

问题 How can I use Angular 2 in production without webserver and just the filesystem? I can't use a webserver because of the corporate policies (that was not a problem with Angular because I could use the filesystem). 回答1: If you don't need network, Angular (version 2 and higher) applications work with no problems over the file:/ protocol. But you must set a correct base href path in your index.html . If you are using Angular CLI, you can build the app using the following command: ng build --base
