The previous behavior was incorrect because `if` was checking the return status of the `[` command which was never going to be an error. `[` seems to only return an error if no args are provided. This was basically a useless use of `[` anyway since it was just meant as a straight interpretation of command exit, something that `if` can do itself. Compare: ```sh [ ]; echo ?=$? [ /bin/false ]; echo ?=$? if [ /bin/false ]; then echo this is the unintended bug; fi if /bin/false; then echo this will not be printed; fi ```

## Grimshot: a helper for screenshots within sway
|
|
## Requirements:
|
|
## - `grim`: screenshot utility for wayland
|
|
## - `slurp`: to select an area
|
|
## - `swaymsg`: to read properties of current window
|
|
## - `wl-copy`: clipboard utility
|
|
## - `jq`: json uliity to parse swaymsg output
|
|
## - `notify-send`: to show notifications
|
|
## - `mktemp`: to create a temporary file
|
|
## Those are needed to be installed, if unsure, run `grimshot check`
|
|
##
|
|
## Examples:
|
|
## `grimshot copy win` - to copy current window
|
|
## `grimshot save area` - to select area and save it to default file (Pictures/Grimshot-$datetime.png)
|
|
## `grimshot save screen ~/screenshot.png` - to save screenshot under ~/screenshot.png
|
|
## `grimshot` - usage
|
|
## `grimshot check` - verify if tools are installed
|
