### Test 5 with MacOS's built in echo

| Index | Platform | Test | Result |
| ----- | -------- | ---------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 13 | MacOS | ^echo '\*\*/\*.json' | \*\*/\*.json|
| 14 | MacOS | ^echo "\*\*/\*.json" | \*\*/\*.json|

### Test 6 quote argument with spaces

| Index | Platform | Test | Result |
| -------- | -------- | -------- | ------------ |
| 17 | MacOS | ^echo "--name='xx' --value='yy'" | --name='xx' --value='yy' |
| 18 | MacOS | ^echo '--name="xx" --value="yy"' | --name="xx" --value="yy" |
| 19 | Windows | ^echo "--name='xx' --value='yy'" | "--name='xx' --value='yy'" (failure)|
| 20 | Windows | ^echo '--name="xx" --value="yy"' | '--name="xx" --value="yy"' (failure) |

But if the argument is defined as a variable, we don't need to quote them.

let argument = "--name='xx' --value='yy'"

| Index | Platform | Test | Result |
| -------- | -------- | -------- | ------------ |
| 21 | MacOS | ^echo $argument | --name='xx' --value='yy' |
| 22 | Windows | ^echo $argument | --name='xx' --value='yy' |

| Index | Platform | Test | Result |
| -------- | -------- | -------- | ------------ |
| 23 | MacOS | ^echo '--aa="bbbb"' | --aa="bbbb" |
| 24 | MacOS | ^echo "--aa='bbbb'" | --aa='bbbb' |
| 25 | MacOS | ^echo --aa="bbbb" | --aa="bbbb" |
| 26 | Windows | ^echo '--aa="bbbb"' | --aa=\bbbb" (failure) |
| 27 | Windows | ^echo "--aa='bbbb'" | --aa=bbbb (failure) |
| 28 | Windows | ^echo --aa="bbbb" | --aa=bbbb (failure) |

### Test 7 - fzf with list of parameters

#### Setup

let-env FZF_DEFAULT_OPTS = '--cycle --layout=reverse --border --height=90% --preview-window=wrap --marker="*"'

let log_fmt_str = '%C(bold blue)%h%C(reset) - %C(cyan)%ad%C(reset) %C(yellow)%d%C(reset) %C(normal)%s%C(reset)  %C(dim normal)[%an]%C(reset)'

#### Test 7.1 (preview with git show)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf [--ansi --multi --tiebreak=index --preview='git show --color=always --stat --patch {1}']
)

#### Result 7.1

- Windows - Fails
- MacOs - Fails

#### Test 7.2 (preview with git show - change quoting)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf [--ansi --multi --tiebreak=index  "--preview=git show --color=always --stat --patch {1}"]
)

#### Result 7.2

- Windows - Succeeds
- MacOs - Succeeds

#### Test 7.3 (preview with git show - remove list syntax)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf --ansi --multi --tiebreak=index  --preview='git show --color=always --stat --patch {1}'
)

#### Result 7.3

- Windows - Succeeds
- MacOs - Succeeds
