The command gdalinfo -hist ${path-to-input-tif} is a command used in the GDAL (Geospatial Data Abstraction Library) toolset. It is used to retrieve information and histogram (frequency distribution) of a raster dataset in TIF (Tagged Image Format) format.

Breaking down the command:

• gdalinfo is the utility/command that provides information about raster datasets.
• -hist is an option/flag that instructs gdalinfo to also generate a histogram along with the other information.
• ${path-to-input-tif} is a placeholder that should be replaced with the actual path to the input TIF file. It refers to the file path of the TIF raster dataset you want to retrieve information and histogram for.

When executed, this command will display various information about the specified TIF file such as its size, compression, coordinate system, pixel data type, and georeferencing information. Additionally, it will calculate and output a histogram, which represents the frequency distribution of pixel values in the raster dataset. The histogram can provide insights into the distribution of data values and help in understanding the characteristics of the raster data.
