Sending log output to an external file with BASH

Asked by xperttech in Microsoft Office Suite, Shell Scripting, Linux

Tags: linux, bash

While creating a file (see sample below), I'm sending output to a file, but the output is being sent upon creation of the file and then when executed. How can I limit the output to the execution only?
The "echo" commands outside and inside the script are ran sequentially. And I have the feeling the commands too. I'm new to bash. Can someone clarify this?
