I'm in a Linux class right now and the question was brought up as to if there was a command to see what's in your buffer list inside vi. I searched online to see if I could find anything, but found nothing, so I went ahead and started to attempt creating a script myself, however I cannot seem to get the commands right.

Here's what I have so far:

while [ : ]
do
clear

echo "What buffer position would you like to see?"

read choice

case $choice in
1) '"1p' ;;
2) '"2p' ;;
3) '"3p' ;;
4) '"4p' ;;
5) '"5p' ;;
6) '"6p' ;;
7) '"7p' ;;
8) '"8p' ;;
9) '"9p' ;;
0) '"0p' ;;


esac ; read -n 1 ;

done

I've tried swapping the command for something like this too:

1) vi -c \"1p ;;

Any ideas on how I might be able to pull a vi command out into command line like that? Thank you! (Side note, this is NOT homework or required. I just want to see if it can be done. I asked my professor to help me with it, and even he was stumped)

    Er, :ls lists buffers. Were you perhaps talking about registers? In that case, its :reg [r] – D. Ben Knoble Jan 25 '18 at 16:50
  • @DavidBenKnoble Judging by the code included, I gather that the OP is trying to write a shell script that, from outside of Vim outputs the contents of Vim's registers. – Rich Jan 25 '18 at 17:29

First thing's first: I infer from your code (which uses "1p etc.) that you actually mean "register" when you write "buffer". In Vim terminology, a "buffer" is Vim's in-memory representation of a file (which may or may not actually exist on disk).

Secondly, I gather from your code that what you are trying to achieve is the construction of a bash script that will allow you to query the contents of Vim's registers from outside of Vim.

That said, here is a command that will print the contents of Vim's numbered register "0 (the yank register) from your shell:

vim -es -c'normal "0P' -c%p -cq! -

I leave it as an exercise to you to figure out how to incorporate that into your bash script: it's outside the scope of this site.

Broken down:

  • vim: Run Vim,
  • -es: in silent mode,
  • -c: passing in the commands...
  • normal "0P: use the normal mode command "0P to paste the contents of the "0 register at the start of the buffer,
  • -c%p: print the contents of the buffer (i.e. output it to stdout i.e. the shell)
  • -cq!: quit, discarding the contents of the buffer (which you altered with the "0P command),

See :help vim-arguments, this earlier question, and this one for more details on how this works.
