Aliases do not take any parameters and will run the command, statement, or script verbatim. If for example, an alias named 'bob' is set to 'echo', it will always run exactly 'echo' which will print nothing, even if you run 'bob "some text". | Aliases do not take any parameters and will run the command, statement, or script verbatim.
