How to linux ls in python

The “ls” command in Linux is used to list the contents of a directory. When executed, it displays the names of all files and directories within the specified directory. By default, the output is displayed in alphabetical order, but it can be sorted by size, date, or other criteria using various options. The command can also be used to display file permissions, ownership, and other metadata. Overall, the “ls” command is a fundamental tool for navigating and managing files and directories in a Linux system.. Keep reading below to learn how to linux ls in python.

Linux ‘ls’ in Python With Example Code

If you are a Python developer who works with Linux, you may find yourself needing to use the “ls” command in your Python scripts. The “ls” command is used to list the contents of a directory in Linux, and it can be very useful when working with files and directories in your Python code.

In this blog post, we will show you how to use the “ls” command in Python 3. We will cover how to list the contents of a directory, how to filter the results, and how to sort the results.

To use the “ls” command in Python 3, you will need to use the “subprocess” module. This module allows you to spawn new processes, connect to their input/output/error pipes, and obtain their return codes.

First, you will need to import the “subprocess” module:

import subprocess

Next, you can use the “subprocess.run()” method to run the “ls” command:

result = subprocess.run(['ls', '-l'], stdout=subprocess.PIPE)

This will list the contents of the current directory in long format and store the output in the “result” variable. You can then print the output using the “print()” function:

print(result.stdout.decode())

If you want to list the contents of a specific directory, you can pass the directory path as an argument to the “ls” command:

result = subprocess.run(['ls', '-l', '/path/to/directory'], stdout=subprocess.PIPE)

You can also filter the results of the “ls” command using the “grep” command. For example, if you only want to list files with a “.txt” extension, you can use the following command:

result = subprocess.run(['ls', '-l', '/path/to/directory', '|', 'grep', '.txt'], stdout=subprocess.PIPE)

Finally, you can sort the results of the “ls” command using the “sort” command. For example, if you want to sort the files in a directory by size, you can use the following command:

result = subprocess.run(['ls', '-l', '/path/to/directory', '|', 'sort', '-k', '5'], stdout=subprocess.PIPE)

By using the “ls” command in your Python scripts, you can easily list the contents of directories and work with files and directories in your code.

Equivalent of linux ls in Python

In conclusion, the equivalent of the Linux ls command in Python is the os module. With the os module, you can list the contents of a directory, get information about files and directories, and perform other file system operations. The os module provides a powerful and flexible way to work with files and directories in Python. Whether you are a beginner or an experienced Python developer, the os module is an essential tool to have in your toolkit. So, if you are looking for a way to list the contents of a directory in Python, look no further than the os module.
