The short script below called " testme " writes a message to standard output, then another slightly different message to standard error. We will use this later to show how the shell has parsed the command-line. The script is as follows. This is enough to be able to accurately test what happens in different situations: How the Standard and Error streams are redirected, and how the parameters to the script are parsed.

When we run this script, it writes output and errors to the same place. It also tells us what parameters it was called with:. We can also choose just to hide the errors, but keep the standard output.

Be careful here, because whitespace matters. If you think about it, how else would you be able to pass " hello world 2 " and tell the shell to redirect stdout?
