从shell脚本读取配置文件

Question

我正在寻找类似Pythons的ConfigParser或Perl的Config :: INI的shell脚本。我已经在过去提供了文件来完成这个任务，但我宁愿阅读而不是执行我的“配置文件”。有没有人知道任何与上述可用于shell（或bash）脚本的模块相当的东西？

感谢， 杰里

你不希望它来源，所以你应该：

。读的配置，2.verify线3.eval他们

CONFIGFILE="/path/to/config" 
echo "=$ADMIN= =$TODO= =$FILE=" #these variables are not defined here 
eval $(sed '/:/!d;/^ *#/d;s/:/ /;' < "$CONFIGFILE" | while read -r key val 
do 
    #verify here 
    #... 
    str="$key='$val'" 
    echo "$str" 
done) 
echo =$ADMIN= =$TODO= =$FILE= #here are defined 

样本的配置文件

ADMIN: root 
TODO: delete 

var=badly_formtatted_line_without_colon 

#comment 
FILE: /path/to/file 

如果你运行上面的示例应该得到（未测试）：

== == == 
=root= =delete= =/path/to/file= 

肯定这不是最好的解决方案 - 也许有人发布更好的解决方案。

你可能想看看cfget可与sudo apt-get install cfget安装。

Answer 4

你可以使用bash它自身解释INI值，通过：

$ source <(grep = file.ini) 

示例文件：

[section-a] 
    var1=value1 
    var2=value2

或者你可以使用bash INI -parser，可在The Old School DevOps blog site找到。
