Im trying to run the following makefile:

```
all:
    chmod +x codeWriter.py
    chmod +x parser.py
    chmod +x vmTranslator.py
    chmod +x VMtranslator

tar:
    tar cvf project7.tar README Makefile *.py VMtranslator

clean:
    rm -f *.tar *.pyc os* sys*

```

but for some unknown reason im getting those errors:

```
line 1: all:: command not found
chmod: codeWriter.py: No such file or directory
chmod: parser.py: No such file or directory
chmod: vmTranslator.py: No such file or directory
chmod: VMtranslator: No such file or directory

line 7: tar:: command not found
tar: README: Cannot stat: No such file or directory
tar: Makefile: Cannot stat: No such file or directory
tar: *.py: Cannot stat: No such file or directory
tar: VMtranslator: Cannot stat: No such file or directory
tar: Error exit delayed from previous errors.

```

any idea why?

Thank you!
