* UNIX supports aliasing of commands; aliasing means using a user defined command for a unix command. For eg it is possible to set "list" in place of the regular unix command 'ls' so you can use both 'list' and 'ls' to see the directory contents.

* In UNIX '/' is used to specify file and directory path names. An example use would be to copy a file from another directory to the current directory like cp pictures/me.gif .

* In UNIX, '.' represents the current working directory, whereas '..' represents the parent directory. For eg. to go to the parent directory type cd .. To go to the parent's parent directory the command would be cd ../..
