diskspace

问题 I'd like to monitor disk space requirements of a running process. Ideally, I want to be able to point to a process and find out the net change in used disk space attributable to it. Is there an easy way of doing this in Linux? (I'm pretty sure it would be feasible, though maybe not very easy, to do this in Solaris with DTrace) 回答1: Probably you'll have to ptrace it (or get strace to do it for you and parse the output), and then try to work out what disc is being used. This is nontrivial, as

问题 I have a number of GitHub projects on my disk, but many of them are not in active use. I would like to remove the working files for the time being, because they are stored in the commit history anyway, so I can retrieve them at a later time. The easiest way to remove the files is rm -rf * but it has a number of drawbacks: It doesn't remove dotfiles such as .gitignore If I come back later, git status complains about lots of removed files. I have to work out whether I should commit these

问题 My script is as below. When we run the script, it automatically saves the disk space usage in separate cells. SIZES_1=`df -h | awk 'FNR == 1 {print $1","$2","$3","$4","$5","$6}'` SIZES_2=`df -h | awk 'FNR == 2 {print $1","$2","$3","$4","$5","$6}'` SIZES_3=`df -h | awk 'FNR == 3 {print $1","$2","$3","$4","$5","$6}'` SIZES_4=`df -h | awk 'FNR == 4 {print $1","$2","$3","$4","$5","$6}'` SIZES_5=`df -h | awk 'FNR == 5 {print $1","$2","$3","$4","$5","$6}'` SIZES_6=`df -h | awk 'FNR == 6 {print $1",

问题 I have implemented the following code: Download a zip file using RNFS.downloadFile() Unzip the file using ZipArchive.unzip() Delete the zip file using RNFS.unlink() I can send info from the server indicating how big the zip file is and how big the unpacked directory is. However, how can I detect if there is enough space on the device to download and unzip the file? I assume once I figure this out I can just do a check like this: if (free_space_on_device > zip_size + unpacked_size){ proceed

问题 I've come across a problem using FileOutputStream and BufferedWriter in Java. If my disk space is full and I'm trying to write, it will throw IOException (which is correct), but when calling the writer.close(), it will fail to close the resource, throwing another IOException and keeping the resource opened! Here is my workaround with writer.flush() . It seems to work, but is there a better way to handle this? BufferedWriter writer = null; try { writer = new BufferedWriter(new

问题 This question already has answers here : How to find how much disk space is left using Java? (6 answers) Closed 5 years ago . I am looking for simple solution for finding total disk space and available space of a remove machine using java program. Please help Update There are questions already similar to this with primarily focus on local machine. I was looking solution for remote machine. 回答1: The easiest way to get the remote machine information and also safe way to do is to SSH to the

问题 i want to download a videofile from the web. It is 121 MB. Now i want to pre allocate this 121 MB on the disk (with zeros or what ever) and fill it step by step with the data of the inputstream from the urlconnection. Or with other words: It doesn't matter how much has been downloaded yet - the file size is always the destinated 121MB. Is it possible? thank you 回答1: i got the solution. First of all i write the empty dummy file and then i reopen the empty file and replace the bytes: System.out

问题 I'm hoping this is a simple one. I run a Rails web app where I'm hosting about 100 school websites. The one app handles all the sites, and I have a management interface where we can add and remove schools etc... I want to add a stat to this interface which is the total disk space used by that school. Each schools files are stored in a seperate directory structure so that's easy to find out. The only problem is I need it to be fast. So the question is what's the fastest way to find this info.

问题 I discovered ASP.NET profiles a few years back and found it quick and easy to implement some powerful functionality in my web site. I ended up exclusively using "anonymous" profile properties because I am NOT using ASP.NET membership and wanted to track information and provide personalization for my site's users even though they weren't logged in. Fast forward 3 years and now I am struggling with keeping the size of my aspnetdb database within the 3 GB limit of my hosting provider. I decided
