如何在Eclipse C IDE中使用grep函数（ubuntu）

Question

我有一个包含两行的文件，每行都有一个进程ID及其生成。 我需要打印每一代中有多少个进程，并且只用一个循环就可以完成，并且必须使用grep和wc函数来完成，但是找不到如何在我的IDE中使用grep而不是将其用作终端函数。 我看到应该是这样的：

class PDFDoc():
    def __init__(self):
        self.rsrcmgr = PDFResourceManager()

read_document = PDFDoc()

但这不是我可以在IDE中编写的东西。

有什么想法吗？
