I am using SysProcessExecuteCommand to run linux commands through Codesys, and have no issues when Command=AllowAll. However, when I try to limit the commands allowed to execute, any commands with a special charater (ex. "*", ";", or "|") no longer works. I receive a pResult of 25 (INT), which from my research means "No access rights for this operation".
Just as an example, the command 'find /Test_Folder/*.v' would execute fine with Command=AllowAll, but will not execute when given a Command.0=find instead. The find command will still execute in both situations if the * is removed.
Below are what I have written in the CODESYSCONTROL.cfg file: [SysProcess]
Command.0=cd
Command.1=ls
Command.2=find
Command.3=iptables
Command.4=echo
Command.5=touch
Command.6=printf
Command.7=ftp
Command.8=|
Command.9=;
Command.10=*
Command.11=\*
Command.12=\;
Command.13=\|
I am currently using Codesys V3.5 SP16 Patch 4 and running version 3.6.16.0 of the SysProcess Implementation Library. The device I'm running is CODESYS Control for Linux SL
Can I get help on how to allow the use of special characters in my commands?
Thanks,

I have a general problem with temperature. Raspberry 4. I did everything as in the settings but does not show. Maybe I'm editing the file in the wrong way?

Did you manage to solve the issue?
No, I have not figured out a way to resolve this issue yet.
I have a general problem with temperature. Raspberry 4. I did everything as in the settings but does not show. Maybe I'm editing the file in the wrong way?
tried on version CS 18 SP4 with targeter 4.7.0.0?
