Bash and path issue
 

Attempted running of "filename.py", having "#!/usr/bin/env python" as first line, by commanding "filename" from inside a subfolder of /usr/local failed with error

bash: filename.py: command not found.

I had to command either "python filename.py" or "./filename.py" in order that the python program executes.

Question: how to fix "bash" in order that the directory from where the command was issued is on my path?

thanks, chiendarret

Create this file in folder where by standard system searches for execute, so: "/usr/local/bin" or "$HOME/bin" if this is added to your PATH. Eventually add this directory to PATH environment variable. For example But the first method is preferred.

Your shell will only execute commands that have a clear absolute or relative path prefixing them, or are in a directory defined by your $PATH variable.

Permanent modifications of PATH are done in your shell start-up scripts. See the INVOCATION section of the bash man page for a description of which files it loads when starting on your system.

Thanks
