Git restore accidentally deleted files

	# Az alap koncepció innen származik: http://stackoverflow.com/questions/953481/restore-a-deleted-file-in-a-git-repo

	# Csak a törölt fájlokat akarom visszaállítani a módosítottakat nem (ezt a grep 'D' és cut kombináció biztosítja)
	# Elméleti:

	git co $(git rev-list -n 1 HEAD -- <file_path>)~1 -- $(git diff --name-status $(git rev-list -n 1 HEAD -- <file_path>)~1 head \| grep '^D' \| cut -f 2)

	# Egysorban az egész db könyvtáron mint példa:

	git co $(git rev-list -n 1 HEAD -- db)~1 -- $(git diff --name-status $(git rev-list -n 1 HEAD -- db)~1 head \| grep '^D' \| cut -f 2)

How to make an activerecord model use a tempory table or view dynamically per query

	# Creating view or temp table
	ActiveRecord::Base.connection.execute("CREATE TEMPORARY TABLE users#{args.offset} SELECT * FROM users LIMIT #{limit} OFFSET #{(args.offset - 1) * limit}")

	# or
	ActiveRecord::Base.connection.execute("CREATE VIEW users#{args.offset} AS SELECT * FROM users LIMIT #{limit} OFFSET #{(args.offset - 1) * limit}")

	### Giving relation back, suitable for find_in_batches

	#User.arel_table.name ='users2'
	# This changes table name in FROM part of the query
