5# These options are used to have safer shell commands. Option '-e' is used to
6# exit on error and option '-u' is used to give error for unset variables.
7# Option '-f' disables pathname expansion which can be useful when $f, $fs, and
8# $fx variables contain names with '*' or '?' characters. However, this option
9# is used selectively within individual commands as it can be limiting at
10# times.

16# is newline. You need to consider the values of these options and create your
