Mac OS是Unix系統(tǒng)的分支蝶押，有著強大的命令行功能。很多事情在命令行下處理會事半功倍膘盖，所以我就iOS程序員可能會用到的功能講述一下衩椒。
終端設(shè)置
Mac的終端有一個很關(guān)鍵的配置，就是“使用 Option 鍵作為 Meta 鍵”惹资。勾上這個選項之后贺纲，就可以使用Emacs的編輯命令了。
Snip20150413_5
我發(fā)現(xiàn)有些人的終端沒有設(shè)置“平滑文本”褪测，導(dǎo)致終端上的文字很難看猴誊。趕緊把這個選項勾上吧。
Snip20150413_7
常用的幾個快捷鍵如下侮措。
- control+a稠肘，跳到命令行開始位置；control+e萝毛，跳到命令行結(jié)尾位置项阴。
- option+f，向前跳一個word笆包；option+b环揽，向后跳一個word。
- option+d庵佣，向后刪除一個word歉胶；option+delete，向前刪除一個word巴粪。
- control+_通今，撤銷之前一次編輯操作。
- control+k肛根，刪除到行尾辫塌；control+u，刪除到行首派哲。
終端顏色高亮也不錯臼氨，看起來感覺會更有感覺。比如ls可以看到目錄會是藍(lán)色的芭届，普通文件是白色的储矩，可執(zhí)行程序會是綠色的感耙。

具體設(shè)置可以參考：讓Mac OS X的終端多姿多彩。
homebrew
homebrew是一個非常有用包管理工具持隧，通過homebrew可以安裝更多有用的unix工具即硼，比如wget、tree等等屡拨。
安裝
目前最好的安裝方式都是下面這樣的只酥，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這個工具看目錄的內(nèi)容非常直觀好看洁仗。

GNU Coreutils包含了各種GNU好用的工具层皱。根據(jù)我的觀察性锭，我發(fā)現(xiàn)Mac預(yù)裝了Coreutils赠潦，只是版本比較低，建議自己安裝一下草冈，否者sort連"-h"參數(shù)都沒有她奥。具體安裝和配置的方法在讓Mac OS X的終端多姿多彩這篇文章里面也有。

Xcode圖形化操作挺好用的怎棱，不過知道一些命令行的操作會更佳哩俭。在下面這個地方看到Xcode編譯的詳細(xì)過程。
Snip20150413_3
如果在編譯的時候遇到鏈接錯誤拳恋，在命令行下檢查一下就非常有必要了凡资。下面這個命令就是鏈接生成來往二進制程序的，可以拷貝到終端里面運行谬运。如果鏈接出錯誤了隙赁，可以仔細(xì)檢查一下這個命令。

vim
做簡單的文本編輯和分析，vim是非常方便的温算。最簡單有用的配置如下怜校。在HOME目錄下創(chuàng)建.vimrc隱藏文件，把下面的內(nèi)容拷貝進去即可注竿。
syntax on #支持語法高亮茄茁，看源代碼文件會很舒服。
set hls #使用 / 查找內(nèi)容的時候巩割，會高亮字符串裙顽。
set ic #搜索的時候忽略大小寫
CocoaPods
CocoaPods的源都安裝在"~/.cocoapods/repos"目錄下，有時候找不到pod宣谈、版本有問題愈犹、或者想確定一下pod的信息，都可以來這個地方翻一翻。
[~/.cocoapods/repos]$ ls

[~/.cocoapods/repos]$ ls TBMainClientSpecs/

sqlite
Mac自帶了sqlite命令行工具饭玲。小工具用起來很快很方便。所以簡單介紹一下怎么使用這個工具叁执。其實".help"講得很詳細(xì)啦茄厘。
[~/Downloads]$ sqlite3 laiwang.sqlite3
SQLite version 3.8.5 2014-08-15 22:37:57
Enter ".help" for usage hints.
sqlite> .tables
lw_messages lw_session_event_post
lw_offline_post2 lw_sessions
sqlite> .schema lw_sessions
CREATE TABLE lw_sessions (primaryKey INTEGER primary key autoincrement, sessionId TEXT, userId TEXT, title TEXT, icon TEXT, content TEXT, sourceType TEXT, data BLOB, actionType TEXT, actionContent TEXT, senderId TEXT, settings BLOB, unreadCount INTEGER, pushEnnabled INTEGER, lastModify TEXT, ancientStampInDB TEXT, recentStampInDB TEXT, sortIndex INTEGER, background TEXT, members BLOB);
CREATE UNIQUE INDEX idx_sessions_SidUidSt ON lw_sessions(sessionId, userId, sourceType);
CREATE INDEX idx_sessions_UidStSiLm ON lw_sessions(userId, sourceType, sortIndex, lastModify);

Python
Python有很多好用的模塊，做一些事情非常便利谈宛。
SimpleHTTPServer
SimpleHTTPServer模塊絕對是Python最有用的一個模塊（另外一個可能是json）次哈。一個命令就能啟動一個Web服務(wù)器，做演示或者mock接口吆录，不要太方便了窑滞。
$ python -m SimpleHTTPServer 9876
Serving HTTP on 0.0.0.0 port 9876 ...
JSON格式化
使用json.tool模塊格式化JSON字符串很方便。
$ python -m json.tool < /tmp/1 <java:10>
{
"address": {
"city": "Nara",
"postalCode": "630-0192",
"streetAddress": "naist street"
},
"age": 26,
"firstName": "John",
"lastName": "doe",
"phoneNumbers": [
{
"number": "0123-4567-8888",
"type": "iPhone"
},
{
"number": "0123-4567-8910",
"type": "home"
}
]
}
nomad houston
nomad houston這個工具支持在命令行下給APP推送信息径筏，感覺蠻不錯的葛假。詳細(xì)介紹請看：使用Houston給iOS APP推送信息障陶。
