age is the difference between the newest and the oldest interface that the library implements.īeware that there is also another similar s/w called fswatch (that is go-related I think).īelow is an abridged version of example on stackoverflow that I've tested and incorporated into one of my projects that requires monitoring of specific directories.

revision is the implementation number of the current interface.

current is the most recent interface number implemented by the library.

"libtool's versioning scheme is described by three integers: Specifically, the 1.14.0 library doc states: Note that the library is versioned differently from fswatch utility itself. Read about fswatch usage here, here and here and a tutorial intro hereĪ library named libfswatch is kept in sync with the fswatch tool. Tips for manually choosing a monitor (currently not updated to mention all monitors)

See how to convert commands for fswatch 0.x to fswatch 1.x There is also extensive documentation for fswatch, though docs for the latest 1.5 version point to 1.4 ones currently. no package for Chocolatey yet, and no package for Vcpkg)

Windows-based package-based installation support doesn't seem to be available yet (e.g.

There is also an other article that shows the same manual process to build/install (and use) fswatch for Linux.

See how to install via apt-get and use fswatch.įreeBSD and OS-X package-based installation support for fswatch is provided by its author.Ĭan also build and install it at other OSes, found an article+video showing how to make and install fswatch on CentOS. It seems to be available via apt-get on Debian/Ubuntu Linuxes. A monitor which periodically stats the file system, saves file modification times in memory and manually calculates file systemĬhanges, which can work on any operating system where stat (2).

A monitor based on ReadDirector圜hangesW, a Microsoft Windows API that reports changes to a directory.

A monitor based on File Events Notification, a Solaris/Illumos kernel API that reports file events.

A monitor based on inotify, a Linux kernel subsystem that reports file system changes to applications.

A monitor based on kqueue, an event notification interface introduced in FreeBSD 4.1 and supported on most *BSD systems.

A monitor based on the File System Events API of Apple OS X.

The list of monitors it currently supports is: It uses different kinds of monitors for different OS and can choose the appropriate one automatically, or allow one to specify which one to use and even pass custom platform-specific parameters to the respective monitor. Albeit with a much worse interface.Īfter searching the answers here and the ones at the other question mentioned as possible duplicate in the comments above, I think I'd go with fswatch since it is has cross-platform support. See the inotifywait answer for a better, and more powerful method of doing this. Note this isn't a failsafe mechanism because the inode could be recycled to a different file name entirely. It's after there is an operation on an inode it hasn't seen. Control of the TTY is not transferred the child process. entr waits for the utility to exit to ensure that resources such as sockets have been closed. A process group is created to prevent shell scripts from masking signals. SIGTERM is used to terminate the utility before it is restarted.

As with the standard mode of operation, a utility which terminates is not executed again until a file system or keyboard event is processed. In this mode entr does not attempt to read from the TTY or change its properties. Files with names beginning with ‘.’ are ignored. This option also enables directories to be specified explicitly.

-d Track the directories of regular files provided as input and exit if a new file is added.

my_watch_dir | entr -dnr echo "Running trigger."Įcho. You can track a directory for new additions using while $(true) do You can install it with apt-get install entr entr was written to make rapid feedback and automated testing natural and completely ordinary. Uses kqueue(2) or inotify(7) to avoid polling. Note entr doesn't use polling giving it a huge advantage over many of the alternatives. Using entr is the new way to do this (it's cross platform).
