mv - "$file" "$newName": renames the file.We then add the extension to that and that gives us the new file name. So here, that will leave us with everything until the last. ext="$ removes the shortest match of pattern from the end of $variable.for file in *: will iterate over all files (and directories) in the current directory, saving each as $file.If you are satisfied they are correct, remove the echo and run again to actually rename. That will just print the commands that will be run. RegexRenamer is a powerful but simple user-friendly graphical tool used to batch rename files using regular expressions. You can just run a little shell loop: for file in * do And, even with those, you would need something slightly different: perl-rename 's/-+_+_+//' *.*Īctually, since all you want is to remove everything after the last -, you could just use: perl-rename 's/(.*)-(.*)(\.*)/$1$2/' *.* Depending on your operating system, that might be available or installable as prename or perl-rename, but you want that one and not the rename from util-linux to use the regular expression syntax you were trying. Thanks and best regards, and please, if I've missed the obvious (i.e.The syntax you tried to use is for the perl rename command. Please, please include this feature, as I haven't found ONE renaming application that allows this, in my travels so far, and it's driving me NUTS! - I have lots of files to rename, and the other logic in your program does EVERYTHING else that I need to catch to make them shorter, remove illegal chars, etc. THAT would make this the "Most Awesome Bulk File / Folder Regular Expression Renamer Ever" for me at least!!! ) I'd LOVE to be able to use your fantastic program with a condition that it leaves alone/does not rename any files that are already under the filename character size limit? 38 chars, a full stop, and a 3 char extension? - Even better, and useful to everyone, would be a specified amount?. an optional checkbox to ONLY rename matching files if the current filename lenght is LONGER than 38.3 chars - i.e. (There's always an erm eh?) - There's ONE feature that would make it DEFINITELY live up the name above, in conjunction with XBOX filename usage?

It shows the preview of file name changes, and populates parameter values when you click or select on the file names. Once you burn out the site, it's awesome for blazing through the directory structure and replacing. Compared to other batch renaming software, it has a dynamic and interactive interface. One quick case study of where I have used it is when converting a ColdFusion driven site into a static site (for CD-Rom creation). I am telling you, this application rocks! It can upper case, lower case, put in time stamps, put in parts of the date, and so very much more. It can recurse, rename, delete, move, copy, alter the date created, alter the date modified. Here is a small screen shot of how it works. In sed and vim the regex to to this would be something like s/(bar)(foo)/21/g, backreferencing the search in the replacement. I think that this application is Freeware so I am posting it here for your benefit. I have A LOT of files named 'barfoo.txt' in a directory, and Id like to rename them to 'foobar.txt' instead. I am not sure if you can find this application online anymore, I am not even sure where I found it. And, it uses regular expressions! How cool is that. Method 3: Script: I use your (modified) script to fix the 2-token number strings. Method 2: Script: I use your (modified) script to fix the 3-token number strings. Method 1: Replace Test with nothing to remove all text up to the number string. This is the best solution that I have ever seen for bulk renaming. Right now, I’m only concerned about the first 3.
