filesplitting

问题 i'm reading a lot of threads - but nothing for me personal. I need to split text file in the following form: --------------------- Instance Type and Transmission -------------- ...text.. ...text.. --------------------------- Message Trailer ------------------------ ...text... ...text... --------------------- Instance Type and Transmission -------------- ...text.. ...text.. dividing content by lines ------------- Instance Type and Transmission -------------- and output text between in newer

问题 Assume a client application that uses a FileSplit object in order to read the actual bytes from the corresponding file. To do so, an InputStream object has to be created from the FileSplit , via code like: FileSplit split = ... // The FileSplit reference FileSystem fs = ... // The HDFS reference FSDataInputStream fsin = fs.open(split.getPath()); long start = split.getStart()-1; // Byte before the first if (start >= 0) { fsin.seek(start); } The adjustment of the stream by -1 is present in some

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . I want to split a 400k line long log file from a particular line number. For this question, lets make this an arbitrary number 300k. Is there a linux command that allows me to do this ( within the script )? I know split lets me split the file in equal parts either by size or line numbers but that's not what I

问题 I have a file that I want to split into 100 pieces. The file size is 257019 bytes. When running my splitter code below I get 99 parts with a size of 2545 byte and the last 100'th part is 5064 byte. I need help to figure out how to make the first 99 parts having the same size and the last 100'th part having the leftover bytes that is equal or lower then 2545. int partSize; for(partSize=1 ;partSize< 257019; partSize++){ if((int) Math.ceil(257019 / partSize) == 100){ break; } } int totalparts =

问题 I have a PDF page of n pages as input. On every m-th page, there is a area which I want to crop and save as an image. Concrete example: 500 page PDF on every 10th page, I want to crop the area from point (10,10) to (110,110) and save it as a single image I think the best solution would be a tool which could do this with just one command line call, so that there is no need for programming with iterations / passing outputs as inputs to other calls. Unfortunately, I haven't found such a tool.

问题 I get a huge XML file containing a list of TV broadcasts. And I have to split it up into small files containing all broadcasts for one day only. I managed to to that but have two problems with the xml header and a node being there multiple times. The structure of the XML is the following: <?xml version="1.0" encoding="UTF-8"?> <broadcasts> <broadcast> <id>4637445812</id> <week>39</week> <date>2009-09-22</date> <time>21:45:00:00</time> ... (some more) </broadcast> ... (long list of broadcast

问题 I have been using the wonderful JQ library to parse and extract JSON data to facilitate re-importing. I am able to extract a range easily enough, but am unsure as to how you could loop through in a script and detect the end of the file, preferably in a bash or fish shell script. Given a JSON file that is wrapped in a "results" dictionary, how can I detect the end of the file? From testing, I can see that I will get an empty array nested in my desired structure, but how can you detect the end

问题 I have an app that records audio using MediaRecorder from MIC whenever a phone call is present, i need to be able to save the last x minutes from this recording when the call is finished - e.g. split the audio file the recording created. I searched for this and all i could find is how to split a .wav file by directly deleting bytes from the file. But i am saving the file in: MediaRecorder.OutputFormat.THREE_GPP with encoding: MediaRecorder.OutputFormat.AMR_NB and I didn't find a way to split
