Full Discussion: Basic question on "echo"
Top Forums UNIX for Beginners Questions & Answers Basic question on "echo" Post 302983610 by Don Cragun on Thursday 13th of October 2016 08:34:04 PM
Old 10-13-2016
All of the discussion so far has ignored a couple of other possible problems... The behavior of echo varies from shell to shell and from system to system and even when using the same version of the same shell it may vary when it is installed on different systems whenever the first argument given to echo starts with a hyphen and whenever any argument given to echo contains a backslash character.

We still have no idea whether ithenr00 is asking about the command echo asterisk or echo *. If the latter is the question, then what is it about filename expansion that needs to be explained? And, what files are in the directory where this command is being executed?
