## Usage

```

❯ mhv -h

A minimalist hex viewer

Usage: mhv [OPTIONS] 

Arguments:

    Target file

Options:

  -s, --skip       Skip `N` bytes of the input. The `N` argument can also

                      include an unit (see `--length` for details). [default: 0]

  -l, --length     Read `N` bytes from the input. None for full read. The `N`

                      argument can be a unit with a decimal prefix(kb, mb).

                      Examples: --length 3kb, -l3kb, --length 1mb...

                      N unis are kb(1000), K(1024), mb(1000 * 1000), M(1024 * 1024),

                      and a prefix 0x for hexadecimal, `0x0a`

  -n, --no-squeezing  Displays all input data. Otherwise any number of output

                      lines which would be identical to the last one are replaced

                      with a line comprised of a single asterisk

  -h, --help          Print help

  -V, --version       Print version

```

* **Read 32 bytes from start**

* **Skip 16 bytes and read 40**

* **Read using units kb(1000), K(1024), mb(1000 * 1000) or M(1024 * 1024)**

* **Read from offset 0x50 plus 16 bytes**
