The test.sh script will provide following help text:

Description:

g.parser test script



Usage:

test.sh [-f] option=name



Flags:

-f a flag



Parameters:

option an option

An option can be instructed to allow multiple inputs by adding the following line:

While this will only directly change the Usage section of the help

screen, the option's environmental string may be easily parsed from within

a script. For example, individual comma separated identities for an option

named "input" can be parsed with the following Bash shell code:

for opt in $GIS_OPT_input ; do

... "$opt"

done

g.findfile
