Python 3 – os.statvfs() Method
In Python, the os
module provides a wide range of functions that allow us to interact with the underlying operating system. One of these functions is os.statvfs()
method, which is used to get the statistics of a file system.
The os.statvfs()
method returns a tuple containing the following file system information:
f_bsize
: the file system block size.f_frsize
: the fragment size.f_blocks
: the total number of blocks in the file system.f_bfree
: the total number of free blocks in the file system.f_bavail
: the total number of free blocks in the file system that are available to the unprivileged user.f_files
: the total number of file nodes in the file system.f_ffree
: the total number of free file nodes in the file system.f_favail
: the total number of free file nodes in the file system that are available to the unprivileged user.f_flag
: file system flags.f_namemax
: maximum length of file names.
Here is an example code block that demonstrates the use of os.statvfs()
method to get the statistics of a file system:
import os
# Path of the file system to get statistics of
path = '/'
# Get the file system statistics
statvfs = os.statvfs(path)
# Print the results
print("File system block size:", statvfs.f_bsize)
print("Fragment size:", statvfs.f_frsize)
print("Total blocks:", statvfs.f_blocks)
print("Total free blocks:", statvfs.f_bfree)
print("Free blocks available to user:", statvfs.f_bavail)
print("Total file nodes:", statvfs.f_files)
print("Total free file nodes:", statvfs.f_ffree)
print("Free file nodes available to user:", statvfs.f_favail)
print("File system flags:", statvfs.f_flag)
print("Maximum length of file names:", statvfs.f_namemax)
This code will output the file system statistics of the root directory of the system:
File system block size: 4096
Fragment size: 4096
Total blocks: 23837118
Total free blocks: 5400200
Free blocks available to user: 4797390
Total file nodes: 6107808
Total free file nodes: 5629526
Free file nodes available to user: 5629526
File system flags: 4096
Maximum length of file names: 255
As you can see, the os.statvfs()
method returns a tuple containing all the necessary information about the file system.
It is important to note that the os.statvfs()
method only works on Unix-like systems, such as Linux and macOS. If you try to use this method on a Windows system, you will get a NotImplementedError
.
In addition, the behavior of the os.statvfs()
method may vary depending on the file system. For example, on some file systems, the f_frsize
value may be the same as the f_bsize
value, while on others it may be different.
Conclusion
In conclusion, the os.statvfs()
method in Python is a powerful tool for getting the statistics of a file system on Unix-like systems. With this method, you can easily get information about the block size, free space, available space, file nodes, and more. It is a great way to monitor the health of your file system and ensure that it is running smoothly.
