Using subprocess to delete multiple files that have a certain string in them-CodePudding

I have a few files with this format:

17-07-39_03-05-2022_Testing.txt 
16-07-34_03-05-2022_Testing.png

"Testing" is the name of the system. I am trying to use subprocess to delete all files that have "Testing" in them at the end.

pc_user = subprocess.run("whoami", capture_output=True, shell=False).stdout.decode().strip("\n")
name, user = pc_user.split("\\")

path = f"C:/Users/Testing/PycharmProjects/pythonProject/Project/"
subprocess.run(f"rm {path}*{name}.*")

I would use a slightly different approach to delete these specific files.

First, you will want to make a list of the paths to all files. It should look like this:

list = ['17-07-39_03-05-2022_Testing.txt', 
        '16-07-34_03-05-2022_Testing.png',
       etc.]

Then, you want to search this list for paths that include the string 'testing' and put all these paths in a new list:

testing_list = []
for path in list:
    if path.find('Testing') > 0:
        testing_list.append(path)

You can now delete all files in the testing_list list. I would use one of the following methods:

os.remove() removes a fil
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

(OP has edited the question since this was posted and removed the powershell tags, making this answer irellevant)

There is a much simpler way to do this using Get-ChildItem and a -like using only powershell.

foreach($file in (gci -path "C:/Users/Testing/PycharmProjects/pythonProject/Project/")){ if($file.name -like "*testing.*"){ remove-item $file.fullname -confirm:$false }}
