使用 SHELL 解析 INI 檔
INI 檔的格式
[Section-A]
Var1=XXX
Var2=XXX
[Section-B]
Var1=XXX
Var2=XXX
範例一
使用：myscript.ksh my.ini <SectionName> <VariableName>
NOTE：在同一個 Section，相同 VariableName 只能有一個值。
#!/bin/ksh
#INI_FILE=path/to/file.ini
#INI_SECTION=TheSection
# BEGIN parse-ini-file.sh
# SET UP THE MINIMUM VARS FIRST
#alias sed=/usr/local/bin/sed
INI_FILE=$1
INI_SECTION=$2
INI_NAME=$3
INI_VALUE=""
eval `sed -e 's/[[:space:]]*\=[[:space:]]*/=/g' \
-e 's/;.*$//' \
-e 's/[[:space:]]*$//' \
-e 's/^[[:space:]]*//' \
-e "s/^\(.*\)=\([^\"']*\)$/\1=\"\2\"/" \
< $INI_FILE \
| sed -n -e "/^\[$INI_SECTION\]/,/^\s*\[/{/^[^;].*\=.*/p;}"`
TEMP_VALUE=`echo "$"$INI_NAME`
echo `eval echo $TEMP_VALUE`

Usage：
# parse the config file called 'myfile.ini', with the following
# contents::
# [sec2]
# var2='something'
cfg.parser 'myfile.ini'
# enable section called 'sec2' (in the file [sec2]) for reading
cfg.section.sec2
# read the content of the variable called 'var2' (in the file
# var2=XXX). If your var2 is an array, then you can use
# ${var[index]}
echo "$var2"
