Mac OS是Unix系統(tǒng)的分支，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，所以我就iOS程序員可能會用到的功能講述一下。
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”。勾上這個選項之后，就可以使用Emacs的編輯命令了。
我發(fā)現(xiàn)有些人的終端沒有設(shè)置“平滑文本”，導(dǎo)致終端上的文字很難看。趕緊把這個選項勾上吧。
常用的幾個快捷鍵如下。
control+a，跳到命令行開始位置；control+e，跳到命令行結(jié)尾位置。
option+f，向后跳一個word；option+b，向前跳一個word。
option+d，向后刪除一個word；option+delete，向前刪除一個word。
control+_，撤銷之前一次編輯操作。
control+k，刪除到行尾；control+u，刪除到行首。
終端顏色高亮也不錯，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，普通文件是白色的，可執(zhí)行程序會是綠色的。
homebrew
homebrew是一個非常有用包管理工具，通過homebrew可以安裝更多有用的unix工具，比如wget、tree等等。
安裝
目前最好的安裝方式都是下面這樣的，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.tgzAlready 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。

shell
GNU Coreutils包含了各種GNU好用的工具。根據(jù)我的觀察，我發(fā)現(xiàn)Mac預(yù)裝了Coreutils，只是版本比較低，建議自己安裝一下，否者sort連”-h”參數(shù)都沒有。
Xcode圖形化操作挺好用的，不過知道一些命令行的操作會更佳。在下面這個地方看到Xcode編譯的詳細(xì)過程。
如果在編譯的時候遇到鏈接錯誤，在命令行下檢查一下就非常有必要了。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。如果鏈接出錯誤了，可以仔細(xì)檢查一下這個命令。

常用的工具如下。
find，查找文件。比如我想分析一下來往源代碼各個部分的文件數(shù)量?？梢园l(fā)現(xiàn)業(yè)務(wù)里面文件數(shù)量最多的三個業(yè)務(wù)分別是扎堆、敲門和聊天。

du，統(tǒng)計目錄大小。比如我想知道來往圖片資源的情況。可以看出圖片資源一共有8.2MB，其中共享的圖片占到2.1MB，其次是聊天的圖片占了1.4MB。
[~/iOS_release/lwimageassets]$ du -sh LWImageAssets8.2M LWImageAssets[~/iOS_release/lwimageassets/LWImageAssets]$ du -sh * | sort -hr2.1M shared_img1.4M chat_img636K event_img528K icon_default524K feed_img472K post_img464K knock_img392K radar_img284K profile_img264K friend_img236K pub_account_map_img140K editor_img132K yifa_img132K emotion_img84K neighbour_img80K lwuikits_img76K discovery_img72K graffiti_img72K asr_img60K login_img52K video_guide_img44K qr_img40K more_img36K share_msg_img32K my_img20K slide_img16K animal_img12K xiamibar_img4.0K search_img4.0K movie_img
file，用于查看文件信息。
$ file libxiamiMusic.a libxiamiMusic.a: Mach-O universal binary with 4 architectureslibxiamiMusic.a (for architecture armv7): current ar archive random librarylibxiamiMusic.a (for architecture i386): current ar archive random librarylibxiamiMusic.a (for architecture x86_64): current ar archive random librarylibxiamiMusic.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 10kSearchTextKeykSearchedPersonKeyinvalid_tokenuser_in_black_listuser_blockedexpired_tokeninvalid_grantrefreshed_tokenclient_idclient_secret
nm，查看可執(zhí)行程序里面的符號信息。
$ nm Laiwang | head -n 1000000001001425e4 t +[ABContact addressWithStreet:withCity:withState:withZip:withCountry:withCode:]0000000100142484 t +[ABContact arrayForProperty:inRecord:]0000000100146438 t +[ABContact contactWithData:]000000010014591c t +[ABContact contactWithDictionary:]000000010014191c t +[ABContact contactWithRecord:]0000000100141984 t +[ABContact contactWithRecordID:]0000000100141b70 t +[ABContact contact]000000010014252c t +[ABContact dictionaryWithValue:andLabel:]0000000100141c50 t +[ABContact localizedPropertyName:]00000001001424e8 t +[ABContact objectForProperty:inRecord:]
vim
做簡單的文本編輯和分析，vim是非常方便的。最簡單有用的配置如下。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。
syntax on #支持語法高亮，看源代碼文件會很舒服。set hls #使用 / 查找內(nèi)容的時候，會高亮字符串。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、版本有問題、或者想確定一下pod的信息，都可以來這個地方翻一翻。
[~/.cocoapods/repos]$ lsTBMainClientSpecs/ alibaba/ master/[~/.cocoapods/repos]$ ls TBMainClientSpecs/AMPSDK/ TBCalendar/ TBLoginCenter/ TBScanCode/ TBWeiTao/AccsSDK/ TBCalendarService/ TBLoginService/ TBScanCodeService/ TBWeiTaoService/[~]$ pod search swiftyjson-> AISwiftyJSON (1.0.6) AISwiftyJSON makes it easy to deal with JSON data in Swift . pod 'AISwiftyJSON', '~> 1.0.6' - Homepage: https://github.com/asiainfomobile/AISwiftyJSON - Source: git@mirror.git.alibaba-inc.com:asiainfomobile/AISwiftyJSON.git - Versions: 1.0.6, 1.0.3 [master repo]-> SwiftyJSON (2.3.2) SwiftyJSON makes it easy to deal with JSON data in Swift pod 'SwiftyJSON', '~> 2.3.2' - Homepage: https://github.com/SwiftyJSON/SwiftyJSON - Source: git@mirror.git.alibaba-inc.com:SwiftyJSON/SwiftyJSON.git - Versions: 2.3.2, 2.3.1, 2.3.0, 2.2.1, 2.2.0, 2.1.3 [master repo]
sqlite
Mac自帶了sqlite命令行工具。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。其實”.help”講得很詳細(xì)啦。

SimpleHTTPServer模塊絕對是Python最有用的一個模塊（另外一個可能是json）。一個命令就能啟動一個Web服務(wù)器，做演示或者mock接口，不要太方便了。

nomad houston
nomad houston這個工具支持在命令行下給APP推送信息，感覺蠻不錯的。
