I am currently modifying "stock" configuration file and making slow progress.
Run into a snag - twice so far.
I can work on the project switching from editing to run all day long, no issue.
Next day i cannot access the file to run it.
The file is still there ( ls...) and to my knowledge still accessible as far as security.
Here is a snippet of terminal output
Code:
....
Debian GNU/Linux comes with ABSOLUTELY NO WARRANTY, to the extent
permitted by applicable law.
Last login: Sun Aug 5 15:03:19 2018 from 10.0.1.41
pi@pi:~ $ cd /usr/bin
pi@pi:/usr/bin $ sudo raspi-config.test
there is no output / reaction after last line and the solution is to exit from terminal.
and stat over.
I am using "remote" ssh to access the file, but I get same behavior when executed locally.
I have no problems editing the file
Code:
pi@pi:/usr/bin $ sudo nano raspi-config.test
just cannot run it after next save.
Any help would be appreciated, but if it is wrong to post here , my apology.
Moderator's Comments:
Please use code tags for all code and data snippets.
Try changing file permissions on the file you want to write to. Then put it in YOUR home directory
Code:
pi@pi:/usr/bin $ sudo mv raspi-config.test /home/pi # move to pi's directory
cd # go to home directory
pi@pi /usr/bin/sudo chown pi raspi-config.test
pi@pi chmod 755 raspi-config.test
# you now own the file and it is in your home directory
# edit the file:
pi@pi: nano raspi-config.test
# if you like the changes copy it back
/usr/bin/sudo cp /home/pi/raspi-config.test /usr/bin/raspi-config.test
# you are running now as the user pi, you only need sudo to cp the file
What this does: basically make a local copy you can play with safely, and without advanced permissions
Not a the best way is to su to root:
Code:
pi@pi: sudo su - root
password [enter your pi user password]
# you are now root, you can generally delete/write/modify permissions on any file in anywhere .... be careful
If you forget you are root you can destroy the whole system with one command. Be careful.
Now you do not need to sudo or anything else except edit the file and do whatever config changes you want.

You may be confusing 'saving' a file with 'closing' a file.
If you save the file in your editor, the editor doesn't know that you've finished and could have the file still locked. If you close the file then you let go of it.
I am using Ctrl X to " Exit " and then save the file in nano editor.
Works OK until I restart my system next day.
Perhaps i need to use Ctrl O "Write out"
As far as changing file location - I just "copy /edited" in /usr/bin where the original is.
It is a good idea since I am very dangerous at this point.
i did checked another copy - with same problem and this is what I got
Code:
pi@pi:/usr/bin $ ls -l raspi-config.copy
-rw-r--r-- 1 root root 53398 Aug 5 16:23 raspi-config.copy
Should I see "x" there ?

Well moving the file did not exactly work
I can list it - ls , edit it , but still no run.
Here is my output , it is title redundant and messy , but I am posting it here in case I did something obviously stupid.
Code:
pi@pi:~ $ pi@pi:/usr/bin $ sudo mv raspi-config.test /home/pi # move to pi's directory
-bash: pi@pi:/usr/bin: No such file or directory
pi@pi:~ $ # you are running now as the user pi, you only need sudo to cp the filepi@pi:~ $ pi@pi:/usr/bin $ sudo mv raspi-config.test /home/pi # move to pi's directory
pi@pi:~ $ cd /usr/bin
pi@pi:/usr/bin $ sudo mv raspi-config.test /home/pi # move to pi's directory
pi@pi:/usr/bin $ cd
pi@pi:~ $ /usr/bin/sudo chown pi raspi-config.test
pi@pi:~ $ nano raspi_config.test
pi@pi:~ $ ls
Desktop oldconffiles python_games wpa_supplicant

pi@pi:~ $ nano raspi-config.test editing works
pi@pi:~ $ raspi-config.test
-bash: raspi-config.test: command not found
pi@pi:~ $ sudo raspi-config.test
sudo: raspi-config.test: command not found
pi@pi:~ $ chmod +x raspi-config.test
pi@pi:~ $ raspi-config.test
-bash: raspi-config.test: command not found
pi@pi:~ $ sudo raspi-config.test
sudo: raspi-config.test: command not found
pi@pi:~ $
I need a break, so Ill wont immediately respond.
Appreciate all the help.
PS I got reprimand for not posting code in tags.
SO I try to copy tagged post but could not figure it out.
Did the normal "cut and paste" using mouse.
SO is there a trick to "copy tagged code "?

Right now we know neither.
What's with "us" and "we" ?
Apparently it is you who needs the info I already shared in my posts.
I am getting good help I need now without "what and why" details.
Hope it will continue.
Can you add anything constructive to the discussion without getting the info you asked for ?
I'm not sure it'd be wise to upset the forum moderators' crew in your fifth post if you want to continue "getting good help" in these fora.

"We" and "us" are the forum members in general, and the suppliers of advice in particular, last but not least the advisors and moderators running these fora.

Again, calm down. I have a guess or two what could be wrong in your setup. Had the info requested by Corona688 been available from the beginning, had you given the entire picture, you might already have gotten a solution to your problem.

Now, this is mentioned in several places, e.g. JUST ABOVE the editor, or in the forum rules and FAQs. Select the code or data section in your post, and click the code button on top of the editor. Repeat for every section if needed.
can you help
