How to pass variable in bash command?

Question

I am trying to convert multiple.doc files to.docx format using antiword. How to write a command like this:

for file in os.listdir(directory):
    subprocess.run("antiword file > file+'.docx'")

it shows this error:

[Errno 2] No such file or directory: "antiword file > file+'.docx'": "antiword file > file+'.docx'"

There is no other way to read.doc file properly that worked for me other than antiword.

Answer 1

Subprocess doesn't run bash. So run bash and pass arguments with arguments remembering about proper quoting.

subprocess.run(["bash", "-c", "antiword \"$1\" > \"$1\".docx", "_", file])
