F2: Fast And Safe Batch Rename Tool For The Command Line (Cross-Platform)

Filed under
Software

F2 is a command-line file and folder batch renaming tool written in Go. The tool is fast, safe (runs several validations before renaming, and allows undoing the batch rename), and runs on Linux, macOS and Microsoft Windows.

The mass rename command line tool is fairly new, having its first stable release back in February 2021, but it's already quite mature, with features like string replacement, insertion of text as a prefix, suffix or other position in the file name, change the letter case, rename using auto-incremental numbers, and so on. Find and replace using regular expressions is also supported.

The tool can show a preview of the new file and folder names (simply omit the -x command line flag, which is used to apply the changes), and it also supports undoing the last batch renaming operation in case you change your mind and want to revert the changes.

To ensure that the rename operations are safe, F2 also runs several validations before carrying out a rename operation. In case the tool finds conflicts, like the target destination already existing, invalid characters in the target path, an empty filename, etc., it can automatically resolve them using the --fix-conficts / -F flag.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
