-#### Batch editing with ex
-Ex is vim's equivalent of `ed` and `ex` is symlinked as `vim -e` on many
-systems. It's equivalent to vim's command line, similar to `ed`, though many
-commands are different
-
-    $ ex file
-    $ vim -Nes file
-Roughly equivalent ways of entering ex-mode. `Q` also works from within vim
-
-    :g/re/p         Globally exectute a command on lines with /re/
-    :v/re/p         Inverse of :g. Executes on all lines without /re/
-    :3,6co$         Copy lines [3,6] to the end of the document
-    :3m6            Move line 3 to line 6
-    :z=3            Pretty print lines in [-2,+2]
-Some infrequently used vim commands are very important in ex-mode
-
-    :g/re/z3
-Prints all the lines and line numbers that contain regex `re`
-
-    :g/bash/exe "normal! cfish\<esc>" | undo | nu
-Changes every line with "bash" to "fish", undoes that, then prints the line
-
-    :g/string/nu | g/num/nu
-Does NOT print all the lines with `string` or `num`. This prints all the lines
-with `string` then reprints them if they also have `num`. `:g` only uses a new
-line to delimit its commands from the next set!
-
-Batch editing style (in bash):
- 1. Here-string: For only one command, here-strings are a quick and easy choice
-
-    $ for f in $(find ~/); do vim -Nes <<<"g/re/p"; done
-Prints all lines with `re` in the home directory. Be careful chaining with `:g`
-
- 2. Here-ansi-c-string: Allows including c-style escape sequences
-
-    $ for f in $(find ~/); do vim -Nes <<< $'g/re/nu\n3'; done
-Prints all lines with `re` then moves to line 3. Often can be avoided with `|`
-
- 3. Here-documents: Probably the best choice for quick batch edits
-
-    $ for file in $(fd -at type subs_)
-    do
-    vim -Nes $file <<'DOC'
-    g/^Stl/exe "norm! cStyle: new\<CR>\<esc>"
-    $ | a
-    # ex: ff=unix:
-    .
-    wq
-    DOC
-    done
-
-Changes The style lines and appends a modeline to files found by `fd`
-
-    $ for file in ~/.bash*; do vim -Nes $file <<EOF
-    a
-    # ex: set syntax=bash:ff=unix:
-    .
-    wq
-    EOF
-    done
-Adds a mode line to all bash dot files in the home directory
-
- 4. Sourced documents: Better for recurring batch edits
-
-    $ fd -a subs_ -x ex < change_font
-    $ fd -a subs_ -x vim -Nes < change_font
-Changes font for all subtitle files. Similar to `vim -S $file`
-
-#### Best practices
-Use `-t file` in `fd`, otherwise `ex` may stop when it hits a directory
-
-Recent version of `fd` seems to consume here-documents and strings. To avoid
-this, use the bash `for` loop syntax as below:
-
-    $ for file in $(fd -at file .); do vim -Ne $f <<<$'nu'; done
-
-Or with here-documents
-    $ for file in $(fd -at file .); do vim -Ne $f <<doc
-    nu
-    doc
-    done
-
-#### Batch editing manually
-    fd -t file . -X awk '$0  ~ / ex:/ { print FILENAME }' | xargs -o vim
-Open all files containing ` ex:` in vim as separate buffers
+See vim_batch_editing.md for practical application of this

+
+# Batch editing with ex
+Ever needed to apply the same edit to several files? Well ex-mode is the only
+generalized solution for this
+
+Ex-mode is vim's equivalent of `ed` and `ex` is symlinked as `vim -e` on many
+systems. Use the `-N` flag for a more familiar experience. Enter this mode while
+in vim with `gQ`. Using the `ex` executable is slightly different from neovim's
+implementation, notably neovim doesn't echo back with `nu` and `p`
+
+```bash
+ex file
+vim -Nes file
+```
+
+Ex-mode uses vim's command-mode syntax, which is similar though different from
+visual mode
+
+```
+:21             Goes to line 21. ^ and $ are for the first and last line
+:10,20d         Deletes lines 10 through 20, inclusive on both ends
+:u[ndo]         Undoes the last action
+:g/re/p         Globally exectute a command on lines with /re/
+:v/re/p         Inverse of :g. Executes on all lines without /re/
+:3,6co$         Copy lines [3,6] to the end of the document
+:3m6            Move line 3 to line 6
+:z=3            Pretty print lines in [-2,+2]
+```
+
+Several commands can be chained with `|`, similar to `;` in bash
+
+```
+:g/bash/exe "normal! cfish\<esc>" | undo | nu
+```
+
+Changes every line with "bash" to "fish", undoes that, then prints the line
+
+    :g/string/nu | g/num/nu
+Does NOT print all the lines with `string` or `num`. This prints all the lines
+with `string` then reprints them if they also have `num`. `:g` only uses a new
+line to delimit its commands from the next set!
+
+## Batch editing styles:
+ 1. Here-string: For only one command, here-strings are a quick and easy choice
+```bash
+for f in $(find ~/); do nvim -Nes <<<"%s/re/p | wq"; done
+```
+
+ 2. Here-ansi-c-string: Allows including c-style escape sequences
+```bash
+for f in $(find ~/); do vim -Nes <<< $'%s/re/nu\nwq'; done
+```
+
+ 3. Here-documents: The best choice for quick batch edits
+```bash
+for file in $(fd -at type subs_); do
+  nvim -Nes $file <<'DOC'
+g/^Stl/exe "norm! cStyle: new\<CR>\<esc>"
+$ | a
+# ex: ff=unix:
+.
+wq
+DOC
+done
+```
+
+```bash
+for file in ~/.bash*; do vim -Nes $file <<EOF
+a
+# ex: set syntax=bash:ff=unix:
+.
+wq
+EOF
+done
+```
+
+ 4. Sourced documents: Better for recurring batch edits. Similar to `nvim -S`
+```bash
+fd -a subs_ -x ex < change_font
+fd -a subs_ -x nvim -Nes < change_font
+
+for f in *.html; do nvim -Nes "$f" < ex_commands; done
+for f in "$(rg -l homu)"; do nvim -Nes "$f" < ex_commands; done
+```
+
+## Best practices
+Use `-t file` in `fd`, otherwise `ex` may stop when it hits a directory
+
+Unless you're really confident, always use files to store commands, then first
+try them out on copies of files you'd like to edit. It's often hard to debug an
+edit in advance and there's no undo
+
+## Batch editing manually
+This isn't really a batch edit... though it's worth mentioning
+
+```bash
+fd -t file . -X rg --files-with-matches 'ex:' | xargs -o vim
+```
