Saving Python File

[Aggie64]

Last week, I created a python file named Blink.py and was able to save it to my directory home/wallis/Blink.py.
Now, I can open the file in python, but when I try to save the file, I get the following error:

[Errno 13] Permission denied:
'/home/wallis/Blink.py'

I would appreciated any help on what I am doing wrong.

Thanks

Can you show the output of:

Code: Select all

ls -l /home/wallis/Blink.py

[Aggie64]

Can you show the output of:

Code: Select all

ls -l /home/wallis/Blink.py

Here is what was listed
-rw-r--r-- l wallis wallis 210 Feb 12 07:38 /home/wallis/Blink.py

The file doesn't have the --x bits set.
chmod 0755 /home/wallis/Blink.py

Also the first line needs
#!/usr/bin/python
or
#!/use/bin/python3

Depending what flavour of python you're writing.
As long as you are logged in as wallis or using root you can write to that file.

sudo nano ... will work.

I am using IDLE3 as the editor where I originally created and saved a python file that now gives me the Error 13.

[DougieLawson]

sudo idle3

That runs idle with root permissions.

[Aggie64]

I tried sudo idle3 and that lets me save the file. I was starting idle3 form the icon on the gui screen before. I am new to linux and the Raspberry pi and I know my issue is a file permissions problem and I will work on this, but in th emeantime I can continue to experiment with my Raspberry pi.

I tried the chmod from a reply i received and it chaned the permissions to:
-rwxr-xr--s l , but I still could not save the file without getting the Errno 13 until i tried sudo idle3.

Thanks guys for helping a beginner.

Can you post the output from
ls -laR /home/wallis
and
grep -e 'wallis' /etc/passwd

[Aggie64]

Here is the response from ls -laR /home/wallis

drwxr-xr-x 2 wallis wallis 4096 Mar 5 14:45 .

Output from grep -e 'wallis' /etc/passwd

I had to hand type the above, so the character alignment is not exactly correct.
Thanks for helping me.

If you're logged in a wallis then there is no reason why you can't read, write or execute your Blink.py program.
I can only assume that your GUI isn't logged in a willis.

Open a LXterminal window and try the whoami command.

[Aggie64]

I went to a terminal window and typed the following:
pi@raspberrypi ~ whoami
pi
pi@raspberrypi ~ su wallis
Password: (entered my password)
wallis@raspberrypi /home/pi $ whoami
wallis
wallis@raspberrypi /home/pi $ cd /home/wallis
wallis@raspberrypi ~ $

I then opened idle 3 from its GUI icon and opened my Blink.py file from the /home/wallis directory and when I try to save the file I still get the Error 13 Permission Denied.
Thanks again

[DougieLawson]

Log out completely.
Login from the prompt as wallis
startx

If you want to change who is logged on by default
sudo nano /etc/lightdm/lightdm.conf
find the line with -user=pi and change that to -user=wallis

[Aggie64]

I logged out and then logged in as wallis and when i typed startx, my screen went black for about 10 seconds and then i got the raspberry gui screen with the raspberry in the middle of the screen, but all my icons such as LXTeminal are gone. There are no icons on the screen.

Thanks again.

[DougieLawson]

sudo cp -R /home/pi/Desktop /home/wallis/Desktop
find /home/wallis/Desktop | xargs sudo chown wallis

Should give you all the same icons as your pi id.

[Aggie64]

Dougie,
I ran the commands you gave me to copy the pi desktop to my wallis user desktop. I then went back and did what you stated earlier

I logged out completely
logged in from the prompt as wallis
startx
sudo nano /etc/lightdm/lighttdm.conf
This time it said new file and as expected there were no lines in the file.

I really know nothing about Linux, so for now I will just stick to running my raspberry as the pi user and start learning more abut Linux and then try switching over to my user name.

I really appreciate the time you have taken to help a beginner on Linux. I know I will be posting more questions on the forum.
