various examples of sed strings within a vi session

PROBLEM:  copied files from another file system over to a different drive, but put them in /home instead of correct directory

	1) first make sure that the files are owned by "fred"
	2) then move the files to a sub-directory showing the old drive, in this case an old 250GB drive
	3) note that sudo is first used to chown (change owner).  
	4) A relative path is chosen, this was run from /home/fred
	5) to create the file, fred typed:   ls ../ > clean
	6) then fred opened the file using vi,   vi clean

		BATCH_XP
		Misc_files
		Pictures
		MP3s
		OLD_320G_IDE-copy-4-2013
		penguin-artifacts
	
	7) then fred typed this string:

		:%s$.*$sudo chown -R fred:users ../& ; mv ../& 250GB-files$g 

		1) the first thing fred hit was  to go into the command mode in vi
		2) the next thing he typed was : (colon), this opened up the ex editor at the bottom
		3) then he typed %s to indicate substitute ALL found in the search, the search delimited by $ (the default is / )
			the search can be limited to specific lines, e.g.  1,15s  or from line 16 to the end,  16,$s
		4) fred used the $ delimiter because there were slashes (/) in the replacement string
		5) after the first $ there is .* (period, star), this means any character, multiple instances (in other words, everthing on the line)
		6) after the second $ the replacement string was typed... if there had been any $ in that string they would need to be "escaped" with a \
		7) in the replacement string fred inserts the original line, represented by & - and inserts that into the actions he'll take.
		8) after the replacement string fred adds the closing $ and g for global.  YMMV in that some versions don't require this.

	8) then fred hit return and the text above was replaced line by line with the following:

		sudo chown -R fred:users ../BATCH_XP ; sudo mv ../BATCH_XP 250GB-files
		sudo chown -R fred:users ../Misc_files ; sudo mv ../Misc_files 250GB-files
		sudo chown -R fred:users ../Pictures ; sudo mv ../Pictures 250GB-files
		sudo chown -R fred:users ../MP3s ; sudo mv ../MP3x 250GB-files
		sudo chown -R fred:users ../OLD_320G_IDE-copy-4-2013 ; sudo mv ../OLD_320G_IDE-copy-4-2013 250GB-files
		sudo chown -R fred:users ../penguin-artifacts ; sudo mv ../penguin-artifacts 250GB-files

	9) fred then saved and exited vi by typing, :wq 
	10) from the command line, fred typed:   sh ./clean
        11) note, fred needed to be in /etc/sudoers to execute sudo, he may have to enter his password during this script.
