I want to run a python script foo.py from the command line like this
$ foo Using a shebang in foo.py, for example:
#!/usr/bin/env python print('this is foo') allows me to call it like this:
$ ./foo.py How do I drop the leading ./ and the trailing .py?
First, rename the file from foo.py to foo.
Then, move the file to /usr/local/bin/ or /home/user/.local/bin if the script will only be executed by a single user. Instead, if your script is placed somewhere in the system for example "/path/to/foo", you could add your "/path/to/foo" to the $PATH variable.
After opening a new terminal session. You should be able to execute the script without the "./" and ".py".
By the way "./" means that you want to execute a file in the current working directory. It is always possible to execute a file using a full path of the file, for example "/usr/bin/something_to_run".
Please consider reading about PATH variable here.
./is there for security reasons. And you can just rename the file.PATH="$PATH:$PWD"PATHsomeone can put a script name like a standard command (for examplels) in some folder. When you enter that folder and runlsthe script will be executed with your rights.
