Use uuid. To tie that into your model see Django documentation for FileField upload_to. For example in your models.py define the following function: import uuid import os def get_file_path(instance, filename): ext = filename.split(‘.’)[-1] filename = “%s.%s” % (uuid.uuid4(), ext) return os.path.join(‘uploads/logos’, filename) Then, when defining your FileField/ImageField, specify get_file_path as the upload_to value. file = … Read more
First, do a dry run (will not actually rename any files) with the following: for file in *.mov do echo mv “$file” “${file/MP4./}” done If it all looks fine, remove the echo from the third line to actually rename the files.
file.rename will rename files, and it can take a vector of both from and to names. So something like: file.rename(list.files(pattern=”water_*.img”), paste0(“water_”, 1:700)) might work. If care about the order specifically, you could either sort the list of files that currently exist, or if they follow a particular pattern, just create the vector of filenames directly … Read more
You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file. Instead of move_uploaded_file($_FILES[“file”][“tmp_name”], “../img/imageDirectory/” . $_FILES[“file”][“name”]); Use $temp = explode(“.”, $_FILES[“file”][“name”]); $newfilename = round(microtime(true)) . ‘.’ . end($temp); move_uploaded_file($_FILES[“file”][“tmp_name”], “../img/imageDirectory/” . $newfilename); Changed to reflect your question, will product a random number based … Read more
If you have all of these files in one folder and you’re on Linux you can use: rename ‘s/test-this/REPLACESTRING/g’ * The result will be: REPLACESTRING.ext REPLACESTRING.volume001+02.ext REPLACESTRING.volume002+04.ext … rename can take a command as the first argument. The command here consists of four parts: s: flag to substitute a string with another string, test-this: the … Read more
A redirect of standard output into arbitrary file name always works. You are doing it correctly as man wget says, using -O wget http://www.kernel.org/pub/linux/kernel/README -O foo –2013-01-13 18:59:44– http://www.kernel.org/pub/linux/kernel/README Resolving www.kernel.org… 149.20.4.69, 149.20.20.133 Connecting to www.kernel.org|149.20.4.69|:80… connected.

First, I should say that the easiest way to do this is to use the prename or rename commands. On Ubuntu, OSX (Homebrew package rename, MacPorts package p5-file-rename), or other systems with perl rename (prename): rename s/0000/000/ F0000* or on systems with rename from util-linux-ng, such as RHEL: rename 0000 000 F0000* That’s a lot … Read more
You could use bash’s parameter expansion feature for i in ./*.pkg ; do mv “$i” “${i/-[0-9.]*.pkg/.pkg}” ; done Quotes are needed for filenames with spaces.
You need to use -M to let git autodetect the moved file when diffing. Using just git diff as knittl mentioned does not work for me. So simply: git diff -M should do it. The documentation for this switch is: -M[<n>], –find-renames[=<n>] Detect renames. If n is specified, it is a threshold on the similarity … Read more
In your specific case you can use the following bash command (bash is the default shell on macOS): for f in *.png; do echo mv “$f” “${f/_*_/_}”; done Note: If there’s a chance that your filenames start with -, place — before them[1]: mv — “$f” “${f/_*_/_}” Note: echo is prepended to mv so as … Read more
