python - 如何在 linux 中的 bash 脚本中为文件提供公共(public)路径

Question

我的脚本是这样的，我想使用变量作为路径以便随时更改它。我如何使用 $path 和 $storage 变量来更改它。实际上我正在将数据从 rrd 文件获取到 xml 文件并想在python中解析它。所以，请纠正我

#!/bin/bash

echo "hello ak"
path= /var/lib/ganglia/rrds/cluster1/ankit21
storage_path= /home/ankit/rrd-xml

rrdtool xport -s -25m DEF:xx=$path/bytes_in.rrd:sum:AVERAGE XPORT:xx:    > $storage_path/bytes_in.xml

python $storage_path/zget.py


And the errors are ...

Answer 1

看来错误在行中

path= /var/lib/ganglia/rrds/cluster1/ankit21

我认为问题是空间......

另外，尝试用引号引起来。

路径="/tmp/测试"

This做一些有趣的阅读。
