file-rename

问题 I am just trying to change the filename extensions to .doc. I'm trying the code below but it does not work. How come? I'm using instructions from here startingDir<-"C:/Data/SCRIPTS/R/TextMining/myData" filez<-list.files(startingDir) sapply(filez,FUN=function(eachPath){ file.rename(from=eachPath,to=sub(pattern =".LOG",replacement=".DOC",eachPath)) }) The output I get is: DD17-01.LOG DD17-02.LOG DD17-03.LOG DD17-4.LOG DD17-5.LOG DD37-01.LOG DD37-02.LOG DD39-01.LOG DD39-02.LOG DD39-03.LOG FALSE

问题 I have a list of files that I need to rename at the same part of each file, with different values. Example: BL_1402B103_abc.wav > BL_C1234-1_abc.wav BL_15489B59_abc.wav > BL_C1234-5_abc.wav So in the first example above I want to replace the 1402B103 with C1234-1 all the files are the same length and the sections I want to replace are separated by " _ ". I have some code for finding/replacing parts of a filename but I need to do this for hundreds of files - is there a way to pull Pattern= &

问题 I am attempting to solve this issue in R, but I'll upvote answers in any programming language. I have an example vector of filenames like so called file_list c("D:/example/sub1/session1/OD/CD/text.txt", "D:/example/sub2/session1/OD/CD/text.txt", "D:/example/sub3/session1/OD/CD/text.txt") What I'm trying to do is move and rename the text files to be based on the part of the parent directory that contains the part about sub and session . So the first file would be renamed sub2_session1_text.txt

问题 I want to allow users to upload images without conflicting problems that may be caused by multiple users uploading images that potentially have the same image name. I am stumped on how to execute this and I have no idea where to start.. Here is my code: if(isset($_POST['submitimage'])){ move_uploaded_file($_FILES['file']['tmp_name'],"pictures/".$_FILES['file']['name']); $con = mysqli_connect("localhost","root","","database"); $q = mysqli_query($con,"UPDATE users SET image = '".$_FILES['file']

问题 I have lots of files in a directory. Example: "/data/2014/file300.data.20141231.MC.9.vgf.img" here 9 represent the hour and change from 1 to 24 ,the date also change. the hours are represented .1. .2. .3. .4. .... .9. I want to replace this part(only this part) in the file name with .01. .02. .03. .04. .... .09. and do not touch any other number in the file name. so .1. become .01. and so on 回答1: Try this with Larry Wall's rename to replace .MC. by .MC.0 : rename 's/\.MC\./.MC.0/' /data/2014/

问题 I have 1000 images that I want to rename them from 1 to 1000. I found this solution (the most voted answer): dirData = dir('*.png'); %# Get the selected file data fileNames = {dirData.name}; %# Create a cell array of file names for iFile = 1:numel(fileNames) %# Loop over the file names newName = sprintf('%04d.png',iFile); %# Make the new name movefile(fileNames{iFile},newName); %# Rename the file end But it falls short when the number of digits from the original file name changes.

问题 What I am trying to do is while my program is using a file, I want to keep the user from renaming, deleting, or moving the file (well... a move is a delete and a create at a different location according to Windows FileSystemWatcher, but I digress). It has been suggested that I use FileStream.Lock or use a Mutex. However, FileStream.Lock seems only to prevent the file from being modified which I am trying to allow . Also, I am very unsure as to if a mutex can lock a file, although I am still
