How do I redirect command output to vim in bash?

Question

I am trying to redirect the output of a bash command into a new file.

If I try the pipe as below :

ls -la | vim

Bash shows me the errors :

Vim: Error reading input, exiting...
Vim: preserving files...
Vim: Finished.

I know that I can open Vim and then use :

:r !ls -la

But is there a way to do this in bash itself, so that Vim is opened and the output is pasted there automatically?

You can use process substitution (this also works with applications that can't read from STDIN):

vim <(ls -la)

Or use vim's function to read from STDIN:

ls -la | vim -

<(ls -la) is actually process substitution rather than command substitution. – Eliah Kagan Sep 02 '14 at 01:32

I really like vim's option, it allows me to search, find and save the output easily from data dumps. – Josue Alexander Ibarra May 11 '16 at 21:36
vim will warn of your buffer is not saved. You may pass -R or -c "setlocal buftype=nofile bufhidden=hide noswapfile" to avoid this. – Jérôme Pouiller Dec 11 '20 at 12:24
This question/answer is the closest to what I've been trying to search on SO, but if anyone can help me: Is it possible to be using a shell (ie bash), and then turn my current shell buffer (ie, everything above my cursor) into a doc I can temp edit in vim? Even read only? For example ls somdir/ and then after it dumps output, i can search and yank from it? Much appreciated!!! – Evan Morrison Jan 28 '21 at 06:17
@EvanMorrison This is a good question, why not asking it? – chaos Jan 28 '21 at 06:27
@chaos Thanks, I did:) – Evan Morrison Jan 29 '21 at 06:29
@EvanMorrison I know that hitting v while typing a command in bash brings up the command in vim. But just the command... – Tom Russell Feb 28 '21 at 20:49
Entering the command ls -la | vim in bash results in Vim: Warning: Input is not from a terminal and vim just exits. But vim <(ls -la) works for me As does its gvim analog. – Tom Russell Feb 28 '21 at 20:50
@TomRussell You need the - (minus) after the command to tell vim to read from the stdin. – chaos Feb 28 '21 at 23:02
@chaos I see my error. Thanks! – Tom Russell Mar 01 '21 at 06:58
Is there a way to make this the default behavior for certain git commands? I have my .zshrc set up to open man pages in vim by default, for example. – Aaron Parisi Jul 20 '22 at 18:16

You're really close on your own. You were just missing one character.

ls -la | vim -

Here's another approach, hopefully to teach someone something new.

If you know that the command :r !ls -la works inside vim, you can do the following to open vim and make it run the command as soon as it opens, straight from bash:

vim -c ':r! ls -la'

This is the equivalent of opening vim then executing the command :r! ls -la. This should work with any vim command, where the command comes after the -c option.

I like it. This results in a little cleaner launch of vim on my system (doesn't hang the bash terminal) but results in the output from git diff missing syntax highlighting. This may be a particularity of my system. – Tom Russell Mar 01 '21 at 07:14
I meant, cleaner launch of gvim... And bash comes back with a carriage return. – Tom Russell Mar 01 '21 at 07:57

You can tell vim to open stdin:

ls -la | vim -

I would like to add an option

ls -al | view -

view is a read-only version of vim(equivalent to vim -R)

setlocal buftype=nofile

This is a good option if you are going to create an alias to replace less:

seq 100 | vim +':setlocal buftype=nofile' -

Now you don't need to type the ! to quit.

Another option is:

seq 100 | vim +'nnoremap q :quit!' -

so you can exit with just q<enter>.

If your goal is simply to get the output into a text file then you don't need to invoke vim. Bash can do it alone with

ls -la > outputfile.txt
