如何从Perl调用python脚本? [英] How to call a python script from Perl?

问题描述

我需要用Perl脚本中很少的参数调用"/usr/bin/pdf2txt.py".我该怎么办?

I need to call "/usr/bin/pdf2txt.py" with few arguments from my Perl script. How should i do this ?

推荐答案

如果您需要捕获 STDOUT :

my $ret = `/usr/bin/pdf2txt.py arg1 arg2`;

您可以轻松捕获 STDERR ，将其重定向到STDOUT:

You can easily capture STDERR redirecting it to STDOUT:

my $ret = `/usr/bin/pdf2txt.py arg1 arg2 2>&1`;

如果您需要获取退出状态，则可以使用:

If you need to capture the exit status, then you can use:

my $ret = system("/usr/bin/pdf2txt.py arg1 arg2");

请记住， `` 和 system() 块，直到程序完成执行.

Take in mind that both `` and system() block until the program finishes execution.

如果您不想等待，或者需要同时捕获STDOUT/STDERR和退出状态，则应使用 IPC :: Open3 .

If you don't want to wait, or you need to capture both STDOUT/STDERR and exit status, then you should use IPC::Open3.
