Code:
mob/verb/Error ()
shell(" cat /home/doniu/arena/Arena.log > log ")
usr << file2text(" log ")


How i can open a file, and read it output in new message box, how to open a message box/window, with the text from file ?

Try using browse()?

The spaces around log are wrong. Also the spaces around the shell command are wrong. Why are you adding spaces you don't need?
