      @stoffel make sure to change to the right folder …

      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

        hallo sdetweil,

        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.

          @stoffel yes, my config module is pretty good…
          waiting for more error reports from users …

          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

              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
              cp config.png

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

              i have no idea what gos wrong

                @stoffel us the file marked excecutable?

                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?

                  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

                    @stoffel said in exec error: Error: Command failed: ?!:

                    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

                      @stoffel said in exec error: Error: Command failed: ?!:

                      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

                        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 !?
