# Show pretty HDD/SSD list
Long time ago when I've switched from Solaris to Linux, I missed the "hd"
utility. In Linux "hd" command is used for hex dump, in Solaris it displayed a
pretty table with HDD info.
I had written "shd" shell script with a similar functionality. After I rewrote
it in Python, added options and pretty colors. The current version 0.1 comes in
Rust, as statically built binaries for x86\_64 Linux, i686, ARM and AARCH64.

## Installation
Install *smartmontools (>=7.0)*, then download the appropriate binary from the
[releases](https://github.com/alttch/shd/releases) page, chmod +x and enjoy.
## Usage
```
shd [-h] [--temp-warn TEMP] [--temp-crit TEMP] [-R] [-y] [-e] [-s] [-f]
--temp-warn TEMP Warning temperature, default: 40 C
--temp-crit TEMP Critical temperature, default: 45 C
-f, --fahrenheit Temperature in Fahrenheit
-R, --raw Suppress colors
-y, --full Display full disk info
-e, --errors Display only disks with errors / critical temperature
-s, --no-header Suppress header
```
## Exit codes
* **1** critical temperature
* **2** errors detected
* **3** smartctl error
The tool considers a drive has errors if its smart status is either not
reported or reported as passed=false.
