END OF PRACTICE + + +NUMBERED BUFFERS +---------------- +In all of the previous pasting exercises you've used the "un-named" +buffer. The un-named buffer contains the text you most recently cut or +copied. When you make a new cut or copy, the old contents of the +un-named buffer are moved to one of the "numbered" buffers. The +buffers are numbered 1-9. Each time you cut or copy text, + + vi saves your current cut or copy in a buffer #1 + vi saves your 2nd to last cut or copy in a buffer #2 + The cut or copy before that is saved in a buffer #3 ... + vi saves your 8th oldest cut or copy in a buffer #8 + vi saves your 9th oldest cut or copy in a buffer #9 + +Note that buffer #1 is the same as the un-named buffer. Here's how to +paste from the numbered buffers: + + "#P (upper p) PUT contents of buffer # before the cursor + "#p (lower p) PUT contents of buffer # after the cursor + +For example: + + "1p PUT buffer 1 after the cursor + "7p PUT buffer 7 after the cursor + +>>> Delete this 1st line with dd +>>> Delete this 2nd line with dd +>>> Delete this 3rd block with d2d +>>> (2nd half of block 3) +>>> Delete this 4th block with dd +>>> Now type "1p "2p "3p "4p + +If you are using vi and have made accidental deletions, just PUT the +contents of each numbered buffer to recover the deleted text. + + +NAMED BUFFERS +------------- +vi maintains the un-named and numbered buffers automatically. You can +maintain your own buffers named a-z. That is, you can cut or copy text +into buffer x and later paste the text from buffer x. + + '"'aDELETE DELETE text into buffer a + "aYANK YANK text into buffer a + "aPUT PUT text from buffer a + +Note, don't actually type 'DELETE', 'YANK', or 'PUT'; type one of the +DELETE commands, YANK commands, or PUT commands.

(In vi you also +exit with 'Z''Z'.) With :w you can save and not quit vi. It is a safe +practice to save changes to a file regularly. This reduces re-typing +in the event your computer crashes. + + :w<RETURN> WRITE contents of the file (without quitting) + (type a colon, type w , then press the RETURN key) + +>>> Try :w now. Note the message at the bottom of the screen. + + +PASTING BETWEEN FILES +--------------------- + +* EMACS-NOTICE: In Emacs there are no problems editing several + files. You can however do it in the more complicated vi way below if + you really want to ;-) + +This is an extremely useful procedure in vi. Only one new command is +required for pasting between files, the EDIT command + + :e filename<RETURN> Begin EDITing the file called "filename" + +The EDIT command allows you to edit another file without quitting vi. +This is useful since named buffers are lost when you quit vi. + +Let's say you want to copy 6 lines from the file called "3temp" into +this file which is named "3cutpaste": +(Note that "3temp" has already been created for you) + + 1) WRITE "3cutpaste". vi will not allow :w (press RETURN) + you to edit another file without first + saving any changes you've made. + + 2) EDIT "3temp" without quitting vi. :e 3temp (press RETURN) + + 3) YANK 6 lines from "3temp". "ay6y + + 4) Return to "3cutpaste". :e 3cutpaste (press RETURN) + + 5) PUT from buffer a "ap + +Note that the un-named and numbered buffers are lost when the EDIT +command is used. Only named buffers are preserved with EDIT. + +>>> Follow the 5-step procedure outlined above. Don't be concerned +>>> with remembering all 5 steps, the instructions are repeated in +>>> "3temp". Paste the text from "3temp" near this line of this file, +>>> "3cutpaste". + +You can use this 5-step procedure on any two files, with any cutting or +copying action (here, y6y is the example). + + +SUMMARY +------- + + #movement repeat movement # times + * EMACS-NOTICE: You may also use 'r' or 'R' in Viper. + + 'd'movement DELETE to where "movement" command specifies + 'd'#movement DELETE to where the #movement command specifies + (e.g. 'd''w' 'd''3''w' ) + + 'y'movement YANK to where "movement" command specifies + 'y'#movement YANK to where the #movement command specifies + (e.g. 'y''w' 'y''3''w' ) + + 'P' (upper p) PUT the contents of the buffer before the cursor + 'p' (lower p) PUT the contents of the buffer after the cursor + + '"'#P (upper p) PUT contents of buffer # before the cursor + '"'#p (lower p) PUT contents of buffer # after the cursor + (e.g. '"''2''p' '"''7''P' ) + + '"'aDELETE DELETE text into buffer a + '"'aYANK YANK text into buffer a + '"'aPUT PUT text from named buffer a + (Note, don't actually type 'DELETE', 'YANK', or 'PUT'; + type one of the DELETE commands, YANK commands, or PUT + commands, e.g. '"''a''d''}' '"''b''y''3''y' '"''c''y''2''0''0''G' '"''d''p' '"''z''P' ) + + :w<RETURN> WRITE contents of the file (without quitting) + (type a colon, type w , then press the RETURN key) + + :e filename<RETURN> Begin EDITing the file called "filename" + + +You are now prepared to handle all cutting, copying and pasting tasks +which may arise.
