我有strace,其中载有所有系统电话。 现在我想获得所有系统的名称。 因此,我要说,如果我有<代码>mprotect,则我只需要一分钟,我只需要列出独特的系统电话。
一种思维方式是使用假装或支持定期表达的其他语言定期表达,首先看所有系统电话,然后消除重复。 为此,我首先尝试利用附注pad++的搜索特征测试我的定期表述。 我想与这一条相匹配。 为此,我制定了以下定期表述:
但笔记没有发现。 你认为,这样做是正确的定期表述?

你们为什么认为需要定期表达这一点? <代码>strace的输出是一系列的线体,从每一条开始。
<c_identifier>(
识别符号可以有<代码>(),因此,你只能参加<代码>()以获得系统名称。 在Adhur,这个一线人对一套不同的系统进行 comp击:
syscalls = set(ln.split( ( , 1)[0] for ln in strace_output)
(如果你在伤口工作而不是在Awk的一线工作,你也可以这样做)。
Notepad++本应告诉你invalid regular expression。 最新版本就是这样。
定期表示,母体具有特别的意义,因此,你必须逃离:
[a-zA-Z_](
<h>(
in blah (
),因为方括号中的部分为t定量(如@CharlesDuffy所指出)。
为了与整个<代码>blah()保持一致,使用
[a-zA-Z_]+(
It should be [a-zA-Z_]+(
instead. This is because round brackets are used as meta characters.
