Maybe I'm not understanding the problem, but "sudo" always wants a password, right? In which case you have to feed it a password with the Exec or Shell command. I'm not a shell script expert (just learning), but I assume that the string would look like this:
Exec [system.shell, "sudo sh -c 'echo out /sys/class/gpio/gpio27/direction'<< EOF\nmypassword\nEOF"] where you have already dimensioned and set the value of "mypassword" in your code. If you have dimensioned a variable like "strShellResponseString", you will be able to display a response from sudo in your program, if the password is incorrect: Exec [system.shell, "sudo sh -c 'echo out /sys/class/gpio/gpio27/direction'<< EOF\nmypassword\nEOF"] TO strShellResponseString note: My additional code is a "here document" code block. "<<" feeds a command list to an interactive program or a command, like sudo. "EOF" means end-of-file, but it also terminates input from stdin. The newline escape code "\n" is needed before and after the password variable, to place the password where sudo expects it, after a linefeed from stdin, followed by another linefeed. And then the second "EOF" terminates this input, which allows sudo to evaluate the password and either execute the sh command, or give an error message if the password is wrong. No extra spaces in all of this, or they'll be interpreted as part of the code! -- View this message in context: http://gambas.8142.n7.nabble.com/shell-tp44500p44508.html Sent from the gambas-user mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
