用python实现抽象shell代码

Question

我分析了一些放在字典里的数据。一些dict值会随着每个读取行而更新。 我想输入这些字典元素使用外壳代码（它必须去一个icinga cmd解析器）

我有点搞不懂怎么用欧斯波本如果要在shell中执行此操作：

/usr/bin/printf“[%lu]添加主机注释；$1；1；CompuWare就绪；$2，$3\n”$now>；$commandfile

$1$2$3必须被dictionary值替换，$现在需要是现有日期（在我的代码中还没有）。你知道吗

也许吧欧斯波本不是去这里的路

谢谢你的帮助和建议

#Script to use external commands
#Add Host Comment , can take up to 30s ! You can add multiple comments if you keep adding them !

from subprocess import call

if len(sys.argv) == 2:

        csv_f = csv.reader(f, delimiter=';')    # create a csv file object
        for row in csv_f:

                dict = {"hostname" : row[0], "group" : "grp_PDU", "service" : "svc_Datacenters", "location" : row[1]}

                #print os.popen("printf " + dict["hostname"]).read() + os.popen("printf " + dict["group"]).read()
                os.popen("printf " + dict["group"]).read()
else:
        print "You did not provide exactly 1 argument. Exiting..."
        sys.exit
f.close()

你真的需要用管道发布主机评论吗？ 我认为，最好的选择是将其放入主机配置并重新加载icinga。你知道吗
