typeset -l section
is creating a variable that will be forced lower case.
Check by typing:
Code:
typeset -l section
section=LSKDHFLKSDHF
echo $section

section=${2:-.}

Means, assign section variable the value of the 2nd command line argument.
If that argument is not set, then set the value of section to a dot.
