Exercise #1 1- Create the following directory maps: TECH172-1 WK01 TECH172-2 ~/LABS WORK01 WKO2 WORKO2 SOFTLINKO1 LK01 SOFTLINKO2 ~/LINK HARDLINKO1 LKO2 HARDLINKO2 2- Create filename /LABS/WK01/TECH0172-1/file1.txt by using vi and write the following statement in it: File and path names There are two ways to reference a file in Unix: a- using a relative path name or using an absolute path name. An absolute path name always begins with a / and names every directory on the path from the root to the file in question. A relative path names a path relative the current working directory. The current working directory is set using the cd command. Note The special name ".." is used to reference the directory above the current working directory. b- There are two ways to reference a file in Unix: using a relative path name or using an absolute path name.
