我有没有shebang的python脚本（它的问题）。当我用相对路径运行它时一切正常，异常直接到终端：
$ python -V
Python 2.6.6
$ cat 1.py
import os
print os.getcwd()
a=b
print c
$ python ./1.py
/home/user
Traceback (most recent call last):
File "./1.py", line 5, in <module>
a=b
NameError: name 'b' is not defined
$
但是只有当类型Control-C指定脚本的绝对路径时才会引发异常（注意跟踪部分之前的代码片段中的^ C符号）：
$ python /home/user/1.py
/home/user
^CTraceback (most recent call last):
File "/home/v-yyushyn/1.py", line 5, in <module>
a=b
NameError: name 'b' is not defined
$
首先，我认为它的行为取决于绝对路径＆＃39;在子shell中运行，但经过短暂的调查后，我发现两个启动都在同一个shell中运行。
是的，可以放置一个shebang并运行脚本而不指定解释器。但有趣的是，在脚本的绝对/相对路径的情况下行为是不同的。
有人建议吗？ 谢谢
更新：python -v /home/user/1.py

客户端已安装abrt automatic bug reporting tool。它拦截异常并将它们发送到专用进程来跟踪崩溃。它是CentOS和Redhat系统上的常见插件（另请参阅Redhat documentation）
该进程挂起，并要求您使用中断来绕过它。
见abrt configuration documentation;内省它正在做什么并将其调整为 not hang 。 abrt FAQ也可能有所帮助;例如，那里列出了用于检查服务状态的命令。
我可以从hook abrt installs看到具有相对路径的脚本被忽略;它只处理具有绝对路径的脚本中的异常（所以/home/user/1.py），这就是为什么你只看到这个问题。
从相同的代码中我们可以看到它会将消息记录到syslog;使用默认值，以便它们最终以/var/log/user.log结尾;注意那里的脚本文件名（1.py）。
很可能与abrtd守护程序的套接字连接已挂起。套接字挂起的原因可能是多种原因including faulty network firmware。
