Mac OS是Unix系统的分支，有着强大的命令行功能。很多事情在命令行下处理会事半功倍，所以我就iOS程序员可能会用到的功能讲述一下。
终端设置
Mac的终端有一个很关键的配置，就是“使用 Option 键作为 Meta 键”。勾上这个选项之后，就可以使用Emacs的编辑命令了。
我发现有些人的终端没有设置“平滑文本”，导致终端上的文字很难看。赶紧把这个选项勾上吧。
常用的几个快捷键如下。
control+a，跳到命令行开始位置；control+e，跳到命令行结尾位置。
option+f，向后跳一个word；option+b，向前跳一个word。
option+d，向后删除一个word；option+delete，向前删除一个word。
control+_，撤销之前一次编辑操作。
control+k，删除到行尾；control+u，删除到行首。
终端颜色高亮也不错，看起来感觉会更有感觉。比如ls可以看到目录会是蓝色的，普通文件是白色的，可执行程序会是绿色的。
homebrew
homebrew是一个非常有用包管理工具，通过homebrew可以安装更多有用的unix工具，比如wget、tree等等。
安装
目前最好的安装方式都是下面这样的，一句命令搞定。
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
使用
[~]$ brew install tree
==> Downloading http://mama.indstate.edu/users/ice/tree/src/tree-1.7.0.tgz
Already downloaded: /Library/Caches/Homebrew/tree-1.7.0.tgz
==> make prefix=/usr/local/Cellar/tree/1.7.0 MANDIR=/usr/local/Cellar/tree/1.7.0/share/man/man1 CC=clang CFLAGS=-fomit-frame-pointer LD
/usr/local/Cellar/tree/1.7.0: 7 files, 128K, built in 2 seconds
tree这个工具看目录的内容非常直观好看。

GNU Coreutils包含了各种GNU好用的工具。根据我的观察，我发现Mac预装了Coreutils，只是版本比较低，建议自己安装一下，否者sort连”-h”参数都没有。
Xcode图形化操作挺好用的，不过知道一些命令行的操作会更佳。在下面这个地方看到Xcode编译的详细过程。
如果在编译的时候遇到链接错误，在命令行下检查一下就非常有必要了。下面这个命令就是链接生成来往二进制程序的，可以拷贝到终端里面运行。如果链接出错误了，可以仔细检查一下这个命令。

常用的工具如下。
find，查找文件。比如我想分析一下来往源代码各个部分的文件数量。可以发现业务里面文件数量最多的三个业务分别是扎堆、敲门和聊天。
[~/ilaiwang/LaiwangV3/Laiwang/PageViews]$ find . -maxdepth 1 -type d -print0 | xargs -0 -I {} sh -c 'echo $(find {} -type f | wc -l) {}' | sort -nr

4 ./IntroducePage
2 ./OAuthPage
2 ./NewGuidePage
2 ./MusicPage
2 ./MoviePage
2 ./DiscoveryExPage
grep，搜索文本。结合正则表达式，分析日志什么的，非常之强大。grep有几个有用的选项，分别是“-r”递归搜索目录；“-i”，忽略大小写；“-c”，统计符合搜索条件的文本的行数；“–color”，高亮搜索结果。
du，统计目录大小。比如我想知道来往图片资源的情况。可以看出图片资源一共有8.2MB，其中共享的图片占到2.1MB，其次是聊天的图片占了1.4MB。
[~/iOS_release/lwimageassets]$ du -sh LWImageAssets

12K xiamibar_img
4.0K search_img
4.0K movie_img
file，用于查看文件信息。
$ file libxiamiMusic.a
libxiamiMusic.a: Mach-O universal binary with 4 architectures
libxiamiMusic.a (for architecture armv7): current ar archive random library
libxiamiMusic.a (for architecture i386): current ar archive random library
libxiamiMusic.a (for architecture x86_64): current ar archive random library
libxiamiMusic.a (for architecture arm64): current ar archive random library
$ file Laiwang
Laiwang: Mach-O 64-bit executable
strings，查看文件中的文本信息。
$ strings Laiwang | head -n 10
kSearchTextKey
kSearchedPersonKey
invalid_token
user_in_black_list
user_blocked
expired_token
invalid_grant
refreshed_token
client_id
client_secret
nm，查看可执行程序里面的符号信息。

vim
做简单的文本编辑和分析，vim是非常方便的。最简单有用的配置如下。在HOME目录下创建.vimrc隐藏文件，把下面的内容拷贝进去即可。
syntax on #支持语法高亮，看源代码文件会很舒服。
set hls #使用 / 查找内容的时候，会高亮字符串。
set ic #搜索的时候忽略大小写
CocoaPods
CocoaPods的源都安装在”~/.cocoapods/repos”目录下，有时候找不到pod、版本有问题、或者想确定一下pod的信息，都可以来这个地方翻一翻。
[~/.cocoapods/repos]$ ls
TBMainClientSpecs/ alibaba/ master/
