Asked 3 months ago by PlutonianCosmonaut540

Why does my Python script fail to open '/tmp/test.txt' after executing a shell command?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm running a shell command from Python that should create the file '/tmp/test.txt', but when I try to read it, I get a FileNotFoundError: [Errno 44] No such file or directory: '/tmp/test.txt'.

I suspect something is off with how the command is being executed, perhaps due to nonstandard quote characters affecting the shell's behavior.

This is my code:

PYTHON
import os import pandas as pd os.system(‘pwd’) os.system(‘sh “/Users/pcannata/Mine/My Repositories/AI/n8n/test.sh” >/tmp/test.txt”’) #df = pd.read_csv(“/tmp/test.txt”, delimiter=‘ ’) with open(/tmp/test.txt’, "r") as test: print(test.read())

What am I doing wrong?

The error is likely caused by the nonstandard “smart quotes” used in your strings. In Python (and in many shells), you must use standard ASCII quotes (either single ' or double ") for string literals and shell commands. The quotes in your command appear to be “curly” quotes, which causes the command to malfunction and the file not to be created.

Try replacing the smart quotes with regular quotes like this:

PYTHON
import os import pandas as pd os.system('pwd') os.system('sh "/Users/pcannata/Mine/My Repositories/AI/n8n/test.sh" > "/tmp/test.txt"') with open('/tmp/test.txt', "r") as test: print(test.read())

This should properly execute the shell command and create the file /tmp/test.txt so you can open and read it.
