我怎样才能用_N_th命令来替代sed(例如,第三次)在一个文件中的再加工(或模式)的发生?我指的是在该文件中发生的_N_th,而不是在一条线路或第一条发生的in the _N_th匹配线中发生的_N_th,而不是在一条线路或第一条发生的in the _N_th匹配线中发生的_N_th。
示例:
只将文件中is的第三次出现改为us。
我的输入文件包含:
hai this is linux.
hai this is unix.
hai this is mac.
hai this is unchanged.
预期产出如下:
hai this is linux.
hai thus is unix.

The kernel source is installed in /usr/src/linux. You should not use this source tree for development because the kernel version against which your C library is compiled is often linked to this tree.
看起来我无法把它和一些非常基本的概念联系起来。

我在我的领域进行了一些集成测试,但是当我在CI上运行时,我得到了以下错误消息:Realm.Sync is not available. Note that the developer edition of the Node.JS SDK for Realm does not include sync on Linux.
我明白消息是什么,我不需要领域同步在我的集成测试。如何在CI环境中禁用Realm.sync?
我已经看过了。它在那里写道:
-- We used to use System.Posix.Internals.dEFAULT_BUFFER_SIZE, which is

我正在尝试从源代码构建openjdk,并且在ubuntu12.04的openjdk6上使用"HOTSPOT_RELEASE_VERSION=20.0-b12“。它会提示:
This OS is not supported:" `uname -a`; exit 1;<br>
This OS is not supported: Linux joker-Inspiron-1545 3.2.0-35-generic-pae #55-Ubuntu SMP Wed Dec 5 18:04:39 UTC 2012 i686 i686 i386 GNU/Linux.
有人能在这方面
My development environment is windows and hosting environment is Linux. At the time of development i have the header:
"#!c:/perl64/bin/perl.exe"
在web服务器上托管时,我需要将所有Perl文件中的头更改为:
"#!/usr/bin/perl"
如果我错过了什么,这个过程就容易出错。这是否可能将Perl文件中的两个标头组合在一起,并取决于操作系统,它会选择正确的头吗?
