本篇內容主要講解“Betty怎么安裝使用”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實用性強。下面就讓小編來帶大家學習“Betty怎么安裝使用”吧!
Betty的安裝非常簡單直接。首先確認你已經安裝了下面這些依賴包[LCTT譯注,需要安裝至少Ruby1.9以上版本]。
sudo apt-get install git curl ruby
yum install git curl ruby
現在用git工具把Betty庫clone到你自定義的任何路徑。這里我克隆到我的home目錄,例如 /home/sk/.
git clone https://github.com/pickhardt/betty
添加betty的別名到你的bashrc配置文件。
sudo nano ~/.bashrc
將下列行添加到文件的末尾:
alias betty="/home/sk/betty/main.rb"
確保你已經正確地設置好了betty的路徑。
好了,現在是時候和betty好好地玩耍了。
你應該在英語短語之前加上單詞“betty”[LCTT譯注,你自然可以用你的小甜心的名字來替換這個不是知道是誰的Betty :>]。你也許已經知道,如果我們想知道在系統中我們的用戶名,應該運行下面的命令:
whoami
輸出是這樣的:
sk
如你所見,我當前登錄的用戶名是 sk. 現在我也可以通過下面的betty命令獲取相同的結果。
betty whats my username
輸出是這樣的:
Betty: Running whoami sk
真的好酷,是不是?Betty理解我輸入的“whats my username”短語,然后運行“whoami”命令,***輸出結果。
讓我們也來看其他命令。
如果你的輸入不夠準確,Betty也能以多種方式回應你。例如,我們運行下面的命令:
betty whats my name
Betty不確定她應該查找系統用戶名還是用戶全名。這種情況下,她會詢問你多個問題來找到準確的結果。如你下面所見,Betty問我想要運行哪一條命令(whoami 還是 finger $(whoami) | sed 's/.://;q')[LCTT譯注,需要你的系統已經安裝finger]。我只想知道我的用戶名,所以我選擇數字1。
Betty: Okay, I have multiple ways to respond. Betty: Enter the number of the command you want me to run, or N (no) if you don't want me to run any. [1] whoami Gets your system username. [2] finger $(whoami) | sed 's/.*: *//;q' Gets your full name. 1 Betty: Running whoami sk
如果你想要壓縮一個文件或者文件夾,用下面的命令。例如,我想壓縮我home目錄下的“test”文件夾。
betty compress test/ test.tar.gz
輸出是這樣的:
Betty: Running tar -czvf test.tar.gz test/ test/ test/home/ test/home/sk/ test/home/sk/test/ test/home/sk/test/sample
類似的,我們可以用下面的命令來解壓縮一個歸檔文件。
betty uncompress test.tar.gz
輸出是這樣的:
Betty: Running mkdir test &&tar -zxvf test.tar.gz -C test test/ test/home/ test/home/sk/ test/home/sk/test/ test/home/sk/test/sample
Betty工具有一些命令格式。如果你輸入“what is my user name”而不是“whats my username”,它是不能識別的。所以,你只能輸入Betty支持的英語短語。
下面給出一個Betty支持的完整的命令行列表。
Count: betty how many words are in this directory betty how many characters are in myfile.py betty count lines in this folder (Note that there's many ways to say more or less the same thing.) Config: betty change your name to Joe betty speak to me betty stop speaking to me Datetime: betty what time is it betty what is todays date betty what month is it betty whats today Find: betty find me all files that contain california Internet: betty download http://www.mysite.com/something.tar.gz to something.tar.gz betty uncompress something.tar.gz betty unarchive something.tar.gz to somedir (You can use unzip, unarchive, untar, uncompress, and expand interchangeably.) betty compress /path/to/dir iTunes: betty mute itunes betty unmute itunes betty pause the music betty resume itunes betty stop my music betty next song betty prev track betty what song is playing (Note that the words song, track, music, etc. are interchangeable) Fun: betty go crazy betty whats the meaning of life ...and more that are left for you to discover!
