Rename files during upload within Wordpress backend

问题 is there a way to rename files during the upload progress within the Wordpress 3.0 backend? I would like to have a consistent naming of files, especially for images. I think an 12 (+-) digit hash value of the original filename or something similar would be awesome. Any suggestions? Regards 回答1: But it would really be easier to do that before uploading files. Not quite sure about that - this seems fairly easy; /** * @link http://stackoverflow.com/a/3261107/247223 */ function so_3261107_hash

How to do a git diff on moved/renamed file?

阅读更多关于 How to do a git diff on moved/renamed file?

问题 I moved a file using git mv . Now I would like to do a diff on the new file to compare it with the old file (with the old, now non-existent name). How do I do this? 回答1: 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 index (i.e. amount

问题 What's the best way to rename photos with a unique filename on the server as they are uploaded, using django? I want to make sure each name is used only once. Are there any pinax apps that can do this, perhaps with GUID? 回答1: Use uuid. To tie that into your model see Django documentation for FileField upload_to.

阅读更多关于 Getting Git to follow renamed and edited files

问题 Questions about renaming files in Git have been asked before, but I can't work out a solution to my specific problem. I have moved and edited multiple files (I didn't use git mv - unfortunately it's now too late for that). Now I want it so when my colleague pulls from my repository, having made his own edits to those same files (without moving them), it successfully merges my changes with his in the file's new location. To successfully merge, Git clearly needs to know that these are the same

Batch renaming files with Bash

阅读更多关于 Batch renaming files with Bash

How can Bash rename a series of packages to remove their version numbers? I've been toying around with both expr and %% , to no avail. Examples: Xft2-2.1.13.pkg becomes Xft2.pkg jasper-1.900.1.pkg becomes jasper.pkg xorg-libXrandr-1.2.3.pkg becomes xorg-libXrandr.pkg richq 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. If all files are in the same directory the sequence ls | sed -n 's/$.*$$-[0-9.]*\.pkg$/mv "\1\2" "\1.pkg"/p' | sh will do your job. The sed command will create a
