Python 3: Using Shell Syntax with subprocess.run()

We can pass in an entire shell command (command name + arguments) as a single string using the run() option shell=True:

from subprocess import run

run( 'echo "Hello, world!"', shell=True )

from subprocess import run

run( 'echo "Hello, world!"', shell=True )

This code has the same effect as run( [ 'echo', 'Hello, world!' ] ).

Using shell=True allows us to use the system's shell operator syntax like > and |. For example, on Linux or macOS, we can run:

from subprocess import run

run( 'curl https://example.com 2>/dev/null | grep iana',
     shell=True )

from subprocess import run

run( 'curl https://example.com 2>/dev/null | grep iana',
     shell=True )
