Mac OS是Unix系統的分支，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。

終端設置

Mac的終端有一個很關鍵的配置，就是“使用 Option 鍵作為 Meta 鍵”。勾上這個選項之後，就可以使用Emacs的編輯命令了。

我發現有些人的終端沒有設置“平滑文本”，導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，跳到命令行結尾位置。
option+f，向後跳一個word；option+b，向前跳一個word。
option+d，向後刪除一個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色的，普通文件是白色的，可執行程序會是綠色的。

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.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容非常直觀好看。

shell

GNU Coreutils包含了各種GNU好用的工具。根據我的觀察，我發現Mac預裝了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，可以拷貝到終端裡面運行。如果鏈接出錯誤了，可以仔細檢查一下這個命令。

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量。可以發現業務裡面文件數量最多的三個業務分別是扎堆、敲門和聊天。

[~/ilaiwang/LaiwangV3/Laiwang/PageViews]$ find . -maxdepth 1 -type d -print0 | xargs -0 -I {} sh -c 'echo $(find {} -type f | wc -l) {}' | sort -nr
914 .
167 ./EventPage
92 ./ChatPage
91 ./KnockPage
88 ./FriendPage
86 ./PubAccountPage
54 ./FeedPage
47 ./SharedPage
44 ./PostPage
29 ./SearchPage
29 ./PhotoEditorPage
29 ./MorePage
28 ./NearByPage
26 ./FriendRadarPage
15 ./LoginPage
14 ./MinePage
14 ./AlbumPage
12 ./PhotoFilterPage
10 ./EmotionBoxPage
9 ./ShareMsgPage
8 ./XiamiPage
8 ./NotificationPage
4 ./IntroducePage
2 ./OAuthPage
2 ./NewGuidePage
2 ./MusicPage
2 ./MoviePage
2 ./DiscoveryExPage

grep，搜索文本。結合正則表達式，分析日志什麼的，非常之強大。grep有幾個有用的選項，分別是“-r”遞歸搜索目錄；“-i”，忽略大小寫；“-c”，統計符合搜索條件的文本的行數；“–color”，高亮搜索結果。

du，統計目錄大小。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 LWImageAssets
8.2M  LWImageAssets

[~/iOS_release/lwimageassets/LWImageAssets]$ du -sh * | sort -hr
2.1M  shared_img

32K  my_img
20K  slide_img
16K  animal_img
12K  xiamibar_img
4.0K  search_img
4.0K  movie_img

file，用於查看文件信息。

$ 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，查看可執行程序裡面的符號信息。

$ nm Laiwang | head -n 10

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目錄下創建.vimrc隱藏文件，把下面的內容拷貝進去即可。

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]$ ls
TBMainClientSpecs/ alibaba/ master/
[~/.cocoapods/repos]$ ls TBMainClientSpecs/
AMPSDK/          TBCalendar/       TBLoginCenter/     TBScanCode/     TBWeiTao/
AccsSDK/         TBCalendarService/    TBLoginService/     TBScanCodeService/ TBWeiTaoService/

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麼使用這個工具。其實”.help”講得很詳細啦。

[~/Downloads]$ sqlite3 laiwang.sqlite3
