为什么Python不运行我的bash代码？

Question

我正在尝试调试为测试集成而提供的一些单元测试。

我确定上次我在本地计算机上测试时效果很好，但这似乎已经改变了 - 文件没有被修改过，所以我不知道＆＃39;从那以后改变了。

我已经删除了识别注释，并更改了原始单元测试中的一些名称，因为它是专有软件。

语法错误是：

  File "unitTests.sh", line 39
    gLastFullPath=`python -c "import os; print os.path.realpath('${1}')"`
                 ^
SyntaxError: invalid syntax

完整的脚本在这里：

#!/bin/bash

# If non-zero, then run in debug mode, outputting debug information
debug=0

# Set the following to 1 to force an error for testing purposes
forceError=0

    # a full path.

这一切都在Python 2.7中运行

这是一个bash脚本，而不是Python脚本。使用./script_name.sh或bash script_name.sh代替python script_name.sh运行它。
