- Make a virtual mosaic from all TIFF files contained in a directory:

`gdalbuildvrt {{path/to/output.vrt}} {{path/to/input_directory/*.tif}}`

- Make a virtual mosaic from files whose name is specified in a text file:

`gdalbuildvrt -input_file_list {{path/to/list.txt}} {{path/to/output.vrt}}`

- Make an RGB virtual mosaic from 3 single-band input files:

`gdalbuildvrt -separate {{path/to/rgb.vrt}} {{path/to/red.tif}} {{path/to/green.tif}} {{path/to/blue.tif}}`

- Make a virtual mosaic with blue background color (RGB: 0 0 255):

`gdalbuildvrt -hidenodata -vrtnodata "{{0 0 255}}" {{path/to/output.vrt}} {{path/to/input_directory/*.tif}}`
