popen() can be used to directly stream data to TAR by creating a subprocess with the TAR command and specifying the stdout argument as the output of popen().

Here's an example code snippet:

import subprocess # Define the command to be executed command = 'tar -cvf archive.tar -' # Use popen() to create a subprocess with the command tar_process = subprocess.Popen(command.split(), stdin=subprocess.PIPE) # Open the file containing the streaming data with open('streaming_data.txt', 'rb') as data: # Stream the data to TAR process tar_process.communicate(input=data.read()) 

In this example, the command specified is to create a new TAR archive named 'archive.tar' and to read data from stdin (specified as '-'). By using popen(), we create a subprocess of the TAR command and redirect the input to be the data read from the file 'streaming_data.txt'. The communicate() method is used to send the data to the subprocess and wait for the process to finish.

popen() can be used to directly stream data to TAR by creating a subprocess with the TAR command and specifying the stdout argument as the output of popen().

Here's an example code snippet:

import subprocessimport subprocess
  # Define the command to be executed command = executed
command = 'tar -cvf archive.tar -'-'
  # Use popen() to create a subprocess with the commandcommand
tar_process = subprocess.Popen(command.split(), stdin=subprocess.PIPE)
 tar_process = subprocess.Popen(command.split(), stdin=subprocess.PIPE) # Open the file containing the streaming data with open('streaming_data.txt', 'rb') as data: data
with open('streaming_data.txt', 'rb') as data:
 # Stream the data to TAR process process
 tar_process.communicate(input=data.read()) tar_process.communicate(input=data.read())

In this example, the command specified is to create a new TAR archive named 'archive.tar' and to read data from stdin (specified as '-'). By using popen(), we create a subprocess of the TAR command and redirect the input to be the data read from the file 'streaming_data.txt'. The communicate() method is used to send the data to the subprocess and wait for the process to finish.
