i have test a lot with file attributes. not needed. magicMirror is not linux, its javascript. only the copy command and pm2 command in the exec function must linux conform. in the pm2 log you have sometimes error messages, but that comes from linux. so you have right, without x-flag its not executable, but MagicMirror ignore file attributes.

now i can cange all my configs with remote-control. for the moment i am finished this module. maybe later i have a new idea, ha,ha.

  exec("pm2 restart " + pm2_id);

after I get the id from pm2 info and find the entry that matches the path we are running under

ok, what can i say. i’v test it with other config und it works also. its overide the old config with the new config and restart mm.
i not understand why, but it works. realy

ok, i am not a linux erpert. i think the exec command execute a script, and its work with this file-attributes. you can test it. maybe its read the file and exec the commands in it. i’v checked the attributes with filezilla, was 644, not executable but it works.

the file-attributes are for the security of RPI & MM importend. thats is for later.

at the moment ist works without errors. i can send you my files for test !?

its a simple text-file

unix is cool… ANYTHING can be executable… and a ‘script’ is just a text file with the executable flag on
the .sh means nothing (just convention to say shell script)

I dson’t use .sh in most of my scripts, cause its just another thing the user has to type and doesn’t help

also, in unix, if the 1st line of the executable text file

starts with shebang #!
then the program to execute this ‘script’ is specified next

#!/bin/bash 

means bash will execute this program, so bash (/bin/bash) is launched and passed this script

and its executable -rw-r–r–

is NOT executable

it needs the x flag

now its executable xrwxr–xr–

there are 3 bits each

for the user themselves
for others in the same group as the user
and for ‘others’

sometimes shortened to UGA

u can set the flags with
chmod the numbers 7 is all bits (777)
or just for the user 766
or read only for anyone except the user 744

to turn on the execute flag for any and all its +x
(to turn it off is -x)
r and w are read and write

look at my first post, its a simple text-file with the extension .sh and its executable -rw-r–r–
the test.sh is not the problem, the file ist found and execute it. the problem was the cp command. but now i soved the problem.

cp -a -v ../MagicMirror/config/config.js ../MagicMirror/config/config_1.js 1>> ./log_erfolgreich.txt 2>> ./log_fehlgeschlagen.txt
pm2 restart all

i add the option -a . now its work !!
the log_erfolgreich.txt and log_fehlgeschlagen.txt are found in the MagicMirror dir, so cp starts at this dir.
the

../MagicMirror/

are needed, maybe mm starts from the .pm2 dir?!

i play around with it and other files (txt, png…)
i am lucky :-)
thanks very much for your help.

at WE i test your config-module and post it

ls -laF ../MagicMirror/config/test.sh

if the file starts with the shebang, then u don’t need to use bash either

#!/bin/bash
rest of script

chmod +x ../MagicMirror/config/test.sh

it is really in the config folder?

i’v test the exec command without bash… thats not work, i have a
/bin/sh: 1: …/MagicMirror/config/test.sh: Permission denied

with bash it works now, but the filename is a bit crazy

thats at ssh console. in filezilla the filename is correct but says no such file or directory

i have no idea what gos wrong

fine, i will test it at WE.
Now its time to sleep. i test tomorrow with sh … and without bash/sh

because you are launching the program (bash) … the console comes to your program not to the log…

in my uploadPics module I just console.log() whatever comes back from my shell pgm…
then it shows in the MM log

have you finished your config-module :face_with_steam_from_nose: ?

the __dirname was from the beginning when i have a file not found error. now its found and i think the exec comand works, in log you can see after the error restart mm but i have no error message from then cp command. so i can not find whats the problem is. in the console.log i have no errors. where can i see error messages from the cp command.

console.log(__dirname) is where the source file is located, NOT the current folder

when modules are executed, the current folder is where the caller is…

pm2 doesn’t launch MM from within the MM folder…

best to use the full path

this.path is the full path to the module folder
