# parseini --- parses 'ini' style configuration files.
|
|
#
|
|
# Usage:
|
|
# awk -f parseini S=<section> P=<param> <ini file>
|
|
#
|
|
# if section is an empty string, then we use the default section
|
|
#
|
|
# example ini file:
|
|
#
|
|
# fruit = apple
|
|
# fruit = pear
|
|
# multiline = this is a multiline \
|
|
# parameter
|
|
#
|
|
# # this is a comment
|
|
# [colors]
|
|
# red = yes
|
|
# green = no
|
|
# blue = maybe
|
|
#
|
|
# [ocean]
|
|
# fish = red
|
|
# fish = blue
|
|
#
|
|
# example usage:
|
|
# > awk -f parseini S=ocean P=fish testfile.ini
|
|
# would return:
|
|
# red
|
|
# blue
