Sure, at first I define “args” and in section two call “args” and define “readconfig” , finally echo them but as I mention give me error! Smilie

Take a look at your "section two" (for whatever reason you split your code in two). What is the sequence of readconf definition and reference?

Code:

}
readconfig < $args

maybe see what you ps returns and what args contains?
