Notes:
Many Unix commands have modifiers which can augment their function. For example "ls -t" will sort files by time of creation or update rather than alphabetically. See the "man" entry for a particular command for details
".alias" files can be used to create a list of aliases for various commands.
For example: alias dr 'ls -alsF' makes "dr" equivalent to Unix command "ls -alsF"
