There are several issues that can be encountered when using the * wildcard in a subprocess command:
Parsing issues: The shell expands the * wildcard before passing it to the subprocess. This can lead to parsing issues if the expanded argument contains special characters such as spaces, quotes, or other wildcards.
Security issues: The * wildcard can be a security risk if the command is not properly sanitized. An attacker could use the wildcard to run arbitrary code.
Performance issues: The * wildcard can be slow if the directory contains a large number of files. The command can take a long time to execute and may use a lot of system resources.
Platform-specific issues: The behavior of the * wildcard can differ between operating systems. For example, on Windows, the * wildcard matches files with any extension, while on Unix-based systems, it only matches files with no extension or with a specific extension. This can cause compatibility issues when using the command on different platforms.
Error handling issues: If the * wildcard does not match any files, the subprocess command may fail with an error. This can cause issues if the script or program relying on the command does not handle errors properly.
