    Hi,

    I'm having trouble editing a configuration file using the SysProcess library.
    I have followed advice and added the following to CODESYSControl_User.cfg:

    [SysProcess]
Command.0=shutdown
Command.1=sed

    I tested my code using the shutdown command, and this was successful. The sed command does not work, instead returns code 25.

    I have found the issue. SysProcess.SysProcessExecute has a restriction on allowed characters. Only alpha numeric and the following are allowed:

    .-+_ :/>"

    So my code does not work due to the '#' symbol.
