:silent exec "!command"
Note that your vim session will still be occupied while your command is executing. This is due to Vim's synchronous nature. You can still get back to your shell by pressing CTRL+z (to send Vim to the background) and then resume vim with the command fg as usual.
To do things asynchronously, take a look at Tim Pope's plugin vim-...

:!{cmd} sends {cmd} to the shell which executes it and shows its output on the screen.
:{range}!{filter} sends the lines from the current buffer inside {range} as the input of the {filter} program and replaces them with its output.
In your example, :%!jq :
% is the range, which means: all the lines of the current buffer
It could also be written 1,$ (from ...

I wrote a pretty extensive answer about this over on stack-overflow. The basic idea is that since the write command is about writing not saving, you can write the text in your buffer into an external program, such as python or bash. In your case, you would want to do something like:
:w !bash
or
:w !sh
These commands literally just write the text in your ...

You can do this with the system function:
let language = system('echo $LANG')
Bonus point: if your output is a list, you can use the systemlist instead to get back a list. e.g.
let files = systemlist('ls')
" ['bin', 'dev', ... ]
ref: :h system

Among all the plugins I have tried, I found ConqueGDB to be the best approach. ConqueGDB uses Conque Shell to embed an interactive shell inside vim, that is used by GDB.
The workflow with ConqueGDB consists not entering GDB commands on the GDB terminal, you use shortcuts on the vim source code. But you can continue using the GDB prompt if you want, for more ...

To execute a command without triggering the Enter message, like:
Press ENTER or type command to continue
try the following simple example:
:silent !echo Hello
Then press Ctrl+L (or :redraw!) to refresh the screen when back to Vim.
To avoid need for refresh, you can define your own custom command, like:
:command! -nargs=1 Silent execute ':silent !'.&...

:grep/:vimgrep both use the quickfix list to store locations. As you have noticed vim will automatically jump to the first occurrence (use ! to avoid this behavior). Simply use :cnext to go to the next location in the quickfix list.
Quickfix commands
:cnext/:cprevious to navigate the quickfix forwards and backwards in the quickfix list
:cfirst/:clast to ...

I find that often the easiest way is to use visual mode with v (or capital V to select whole lines), and select the text you want to pipe.
Then type:
:!cat
This doesn't do anything useful, as such. A useful command I use often is:
:!python -m json.tool
to format JSON.
You can also just type (without visual mode):
:<range>!command
For example, ...

There are a couple of vim plugins that allow for this. I use Conque (Github).
After putting it in your plugins directory all you have to do is:
:ConqueTermSplit bash
And you will have an interactive bash shell in vim. You can then use your regular vim gestures to do anything else you may want to do in the window.
Also the other plugin is vimshell.

You can use gCTRL+g, which will give you:
Col 1 of 118-121; Line 1 of 5; Word 1 of 142; Byte 1 of 678
You can also use this from visual mode, if you want to get the word count for just the selection, which is especially useful combined with text objects such as ip. (e.g. you can use vipg<C-g> to get the word count of the current paragraph).
See: :...

By sheer luck I found out that both:
:%!jq . %
or shorter:
:%!jq .
work, yet I don't understand why this updates the buffer.

As @Carpetsmoker points out in his comment, g:netrw_gx determines what will be considered part of a URI.
By default it is set to "<cfile>". From the docs (:help <cfile>):
<cfile> is replaced with the path name under the cursor
It escapes me, why parameter parts (i.e. ?) of a URL are being disregarded as parts of a "path name", but I ...

Don't be so inefficient! Your time is valuable. Use the vimtex plugin offered by @lervag: see here. You can control all of the plugins you install by using Vundle or any similar plugin manager (vim-plug is getting pretty popular).
Why waste your time installing vimtex? Great question!

You could delete the text and insert the output of a command using CtrlR-=:
CTRL-R {0-9a-z"%#*+:.-=} i_CTRL-R
Insert the contents of a register. Between typing CTRL-R and
the second character, '"' will be displayed to indicate that
you are expected to enter the name of a ...

Using :execute
All command arguments in Vim are interpreted literally unless designed to be evaluated. To build a command dynamically, you can use :execute. Each argument to :execute is evaluated, and they are all joined by a space to produce the final command.
function Compile_and_run(game, major, minor)
execute '!_compile' a:game a:major a:minor

I actually fixed this myself a long time ago. The problem is that when you run !python you're starting up a new shell with your existing environment. But, this means workon xxxx wasn't called to actually activate the virtualenv. This lead to a lot of confusion for me since $VIRTUAL_ENV was set.
I got around it by adding the following to my ~/.zshenv ...

You have several plugins that integrates gdb.
We used to have pyclewn. The project has been discontinued after version 2.3. The last commit has been made in 2016. For the curious ones there is still a mirror on github where its author has archived his work. Note: pyclewn used to be the last stage step in the evolution of the other Xavier Degaye's *clewn ...

A quick and dirty solution (in pure Vimscript)
This can start a process in the background:
:!slow_command_here > /tmp/output 2>&1 &
But Vim needs a way to find out when the process has completed, and how, so let's use a marker file:
:!(rm -f /tmp/finished; slow_command_here > /tmp/output 2>&1; echo "$?" > /tmp/finished) &

Your issue is with bash and not with vim. The problem is that when you run !<cmd> in vim or /bin/bash -c <cmd> from another shell you are launching an instance of bash in non-interactive mode. In non-interactive mode alias are not expanded and you get this error. I don't know if you'd be able to enable the shell option expand_aliases from these ...

You were close. Enclose the path pattern in single quotes instead of double quotes for the find command like so:
args `find . -type f -not -path '*/\.*'`
By the way, a handy way to ignore hidden files is to use :args **. But this will include folders too.
I'm not completely sure why you need to enclose it in single quotes, I believe that Vim will evaluate ...

You could use :make for this; you can set makeprg (short for make program) to any command.
Some examples:
au FileType ruby set makeprg=ruby\ %
au FileType javascript set makeprg=node\ %
au FileType python set makeprg=python\ %
au FileType coffeescript set makeprg=coffee\ -c\ %
noremap ,b :make<CR>
:make was originally intended to run the make tool ...

When you execute an external command with :!, Vim doesn't know what the external command might have written to the terminal, so it waits for you to confirm that you are ready to continue.
To avoid that, you can use the system() function like this:
autocmd BufWritePost *.cpp call system("ctags -R")
autocmd BufWritePost *.h call system("ctags -R")

Vim displays the "Press ENTER" prompt when the number of lines printed in the command area is greater than the number of lines it has available. This is to ensure the user doesn't miss a message.
The issue has been documented in Vim's help (:h press-enter) and also addressed on the VimTips wiki.

You can use the "filter" command,:!, which like most commands can be prefixed with a range:
:{range}!cmd
If you prefix this with a range, it will pipe those lines to the command's stdin, and replace those lines with the program's output. In this case you want to use % as the range, which means the entire buffer. For example:
:%!sort
You can find the Vim ...

You have a couple of options here:

endfunction

This works as designed, and is documented under :help :silent:
":silent" will also avoid the hit-enter prompt. When
using this for an external command, this may cause the
screen to be messed up. Use |CTRL-L| to clean it up
then.
You can also use the :redraw command.

Why doesn't this work?
This doesn't work for exactly why you say, vim is replacing the % with the path.
So, your non working line
:! mv % ${%/.txt/.asc}
is expanding to
:! mv myfile.txt ${myfile.txt/.txt/.asc}
which bash will call a bad substitution; You are trying to expand a variable called myfile.txt, and bash doesn't support variable names with . ...

Mentioned in the comments above, the v:shell_error variable gives the result of the last shell command. So the exit status can be tested as follows:
let output = system("my_shell_command")
if v:shell_error != 0
echo output
