# BASH3 Boilerplate: ini_val
|

#
|

# This file:

#
|

# - Can read and write .ini files using pure bash
|
||||
#
|
||||
# Limitations:
|
||||
#
|
||||
# - All keys inside a section of the .ini file must be unique
|
||||
# - Optional comment parameter for the creation of new entries
|
||||
#
|
||||
# Usage as a function:
|
||||
#
|
||||
# source ini_val.sh
|
||||
# ini_val data.ini connection.host 127.0.0.1 "Host name or IP address"
|
||||
#
|
||||
# Usage as a command:
|
||||
#
|
||||
# ini_val.sh data.ini connection.host 127.0.0.1 "Host name or IP address"
