This article mainly introduces "what is the role of pyinotify in Linux". In daily operation, I believe that many people have doubts about the role of pyinotify in Linux. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what is the role of pyinotify in Linux?" Next, please follow the editor to study!

Pyinotify is a simple and useful Python module that can be used to monitor file system changes in Linux in real time.

As a system administrator, you can use it to monitor changes to directories you are interested in, such as Web directories or program data storage directories and other directories.

It relies on inotify (the Linux kernel feature included in kernel 2.6.13), which is an event-driven notifier whose notifications are exported from kernel space to user space through three system calls.

The purpose of pyinotiy is to bind these three system calls and provide a generic and abstract way to manipulate these functions.

In this article, we will show you how to install and use pyinotify in Linux to monitor file system changes or modifications in real time.

Dependence

To use pyinotify, your system must be running:

Linux kernel 2.6.13 or higher

Python 2.4 or higher

How to install Pyinotify in Linux

First check the kernel and Python versions on the system:

# uname-r # python-V

Once the dependency is satisfied, we will install pynotify using pip. In most Linux distributions, if you are using the binary Python 2 (> = 2.7.9) or Python 3 (> = 3.4) downloaded from python.org, then pip is already installed, otherwise, install it as follows:

# yum install python-pip [On CentOS based Distros] # apt-get install python-pip [On Debian based Distros] # dnf install python-pip [On Fedora 22 +]

Now install pyinotify:

# pip install pyinotify

It installs the available version from the default repository. If you want a stable version of * *, you can clone it from the git repository as follows:

# git clone https://github.com/seb-m/pyinotify.git # cd pyinotify/ # ls # python setup.py install

How to use pyinotify in Linux

In the following example, I monitored the changes under the user tecmint's home directory (/ home/tecmint) as the root user (logged in through ssh), as shown in the screenshot:

# python-m pyinotify-v / home/tecmint

Monitor directory changes

Next, I will observe any changes to the web directory (/ var/www/html/tecmint.com):

# python-m pyinotify-v / var/www/html/tecmint.com

To exit the program, just press Ctrl+C.

Note: if you do not specify a directory to monitor when you run pyinotify, / tmp will be the default directory.

At this point, the study on "what is the role of pyinotify in Linux" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
