阅读更多关于 Creating nested directories on server using JSch in Java

问题 I am making an application for file uploading in Java using jSch . I want to put my file in different directories based on their creation date etc. I have a main directory "/var/local/recordingsbackup/" in which I am creating other directories and putting data in them. To achieve this: I have to create Dir'y like "/var/local/recordingsbackup/20140207/root/SUCCESS/WN/" and put data in it. I've tried this so far: private void fileTransfer(ChannelSftp channelTarget, temp_recording_log recObj,

阅读更多关于 mkdir() says theres no such directory and fails?

问题 Im likely doing something very simply wrong, but when I try to make a directory (using a variable of an insert just performed as the last folder name), I get the error: Warning: mkdir() [function.mkdir]: No such file or directory in /home/blah/blah with the code: if (!is_dir("images/listing-images/rent/'.$insertID.")) { //make new directory with unique id mkdir("images/listing-images/rent/'.$insertID."); } of course the directory doesn't exist..

I am wondering what I am doing wrong. I'm inside of PATH and I want to create a folder inside of PATH. I want to check if the folder already exists and, if not, create one. Getting the name of the folder from an input field with name of "dirname". if (isset($_POST['createDir'])) { //get value of inputfield $dir = $_POST['dirname']; //set the target path ?? $targetfilename = PATH . '/' . $dir; if (!file_exists($dir)) { mkdir($dir); //create the directory chmod($targetfilename, 0777); //make it writable } } thecodeassassin It might be a good idea to make sure that the directory you are handling

mkdir() not working

阅读更多关于 mkdir() not working

My code mkdir("/some/absolute/path",0777); and mkdir("relative/path", 0777); is not working, safe mode is turned off, and I've even tried setting all of the parent folders to 777. Any ideas? EDIT: I do have error reporting turned on, in my frustration I've 777'd the whole path just to make sure that, that isn't the issue. It's gotta be something stupidly simple going on. EDIT EDIT: Upvotes for everyone who responded with suggestions... But I'm not going to select an answer since this still isn't resolved, but then again I think this is going to be one of those ones left open forever. EDIT x 3:

How to use mkdirs in a thread safe manner in Java?

阅读更多关于 How to use mkdirs in a thread safe manner in Java?

After experiencing issues with mkdirs() and poking around the interwebs, I get the impression that there are thread safety issues with mkdirs(). Is there a way to ensure the directories are properly created when it is possible that multiple threads might be trying to create similar file structures? Thanks (In my case I will be using this on Android) Okay, I know this has been inactive for a while, but I thought perhaps there was a simple solution. The article you linked in the comments on the question seems to indicate that the only problem is directories not being created. The solution there

mkdir error in bash script

The following is a fragment of a bash script that I'm running under cygwin on Windows: deployDir=/cygdrive/c/Temp/deploy timestamp=`date +%Y-%m-%d_%H:%M:%S` deployDir=${deployDir}/$timestamp if [ ! -d "$deployDir" ]; then echo "making dir $deployDir" mkdir -p $deployDir fi This produces output such as: making dir /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 mkdir: missing operand Try `mkdir --help' for more information. However, if I type /cygdrive/c/Temp/deploy/2010-04-30_11:47:58 on the command-line it succeeds, why does the same command not work in the script? Thanks, Don Change: mkdir -p
