Multiple .tif files in folder

[loon032]

Paragraph Using the GDAL library from the terminal;

fn=$(ls *.tif) can give a list of files to the variable fn if there are multiple .tif files in the given folder.
Which could give problems executing the gdal scripts as it expects to have only one file.
Either describe that you can only have one tif file in the folder or run a warning if there are multiple (and use the first file).
