将 python 脚本 output 存储到 linux 中的变量并运行 wget 命令

Question

So I made a python script that retrieves a url link and returns it as an output. Just to keep it simple, the content of the python script would be just:

print("https://www.testweb.com/file=ejfeafjaiaefjaof")

For example, if i execute the python script in my terminal:

python retrieve_url.py

it outputs:

https://www.testweb.com/file=ejfeafjaiaefjaof

So I then would like to utilize the "wget" command in linux with the url that is returned by my python script, so that i could do something like:

wget https://www.testweb.com/file=ejfeafjaiaefjaof

But instead, is it possible to store the python output url in a variable and execute a linux script in one go? I was thinking something like creating an executable script, run.sh

python retrieve_url.py
wget **some argument to store the python output**

and just use./run.sh.

Answer 1

To save the output of your python script like this

test=$(python test.py)

echo $test
"https://www.testweb.com/file=ejfeafjaiaefjaof"

Answer 2

wget just needs to read the URL from stdin, using -i- flag:

python retrieve_url.py | wget -i-
