# cli_getFont.sh -- This function creates a list of all True Type

# Fonts (TTF) installed in your workstation and returns the absolute

# path of the file matching the pattern passed as first argument.

# Assuming more than one value matches, the first one in the list is

# used. In case no match is found, the function verifies if there is

# any file in the list that can be used (giving preference to sans

# files). If no file is found at this point, an error will be printed

# out.
