fswatch

fswatch 1.18.3, authored by emcrisostomo, is a cross-platform, open-source file change monitor that continuously observes one or more paths and emits event notifications whenever the contents of the specified files or directories are modified. Designed for developers, system administrators, and automation engineers, the utility translates low-level operating-system file-system events into a unified, line-oriented text stream that can be piped directly into shell scripts, build tools, loggers, or any downstream program that needs to react instantly to creations, deletions, renames, permission changes, or data updates. Typical use cases include triggering automatic builds when source code changes, reloading development servers during live editing, synchronizing folders to remote storage, auditing configuration drift, or driving continuous-integration pipelines without polling overhead. Because fswatch abstracts platform-specific APIs such as FSEvents on macOS, inotify on Linux, and ReadDirectoryChangesW on Windows, a single command syntax works identically across laptops, containers, and CI runners, eliminating the need for conditional scripting. The tool supports recursive or non-recursive watching, inclusion/exclusion filters by glob or regular expression, customizable buffering and latency, and multiple output formats from human-readable to JSON, making integration with Ansible, Jenkins, GitHub Actions, or local daemon supervisors straightforward. Only one version—1.18.3—is currently tracked, reflecting the project’s stable, focused scope. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
