如何在終端機打開圖形界面的應用程式?
一般而言, 打開應用程式要透過 Finder 進到 Applications 慢慢找某特定的應用程式. 然後點兩下執行它. 雖然, 常用的應用程式大部份都會依個人偏好放在 Dock 上方便執行. 但是, 總是會有些程式放在 Dock 上. 所以透過 Finder 尋找應用程式然後執行. 某種程度而言算是有點瑣碎. 對有些重度使用 Terminal 的使用者會認為, 如果能用某指令就能打開圖形界面的應用程式那是最好不過的. 尤其透過遠端登入要打開某個程式.那更是方便. 因為遠端沒辦法直接對某應用程式直接執行.
至於, 該怎麼遠端或是透過終端機打開圖形界面應用程式? 簡單來說就使用 open 這個指令. 先大概看一下基本的說明如下 :
$ open
Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-b ] [-a ] [filenames] [--args arguments]
Help: Open opens files from a shell.
By default, opens each file using the default application for that file.
If the file is in the form of a URL, the file will be opened as a URL.
Options:
-a Opens with the specified application.
-b Opens with the specified application bundle identifier.
-e Opens with TextEdit.
-t Opens with default text editor.
-f Reads input from standard input and opens with TextEdit.
-R, --reveal Selects in the Finder instead of opening.
-W, --wait-apps Blocks until the used applications are closed (even if they were already running).
--args All remaining arguments are passed in argv to the application's main() function instead of opened.
-n, --new Open a new instance of the application even if one is already running.
-g, --background Does not bring the application to the foreground.
-h, --header Searches header file locations for headers matching the given filenames, and opens them.
上面的內容就稍微自己看一下吧 : )
就示範幾個範例, 讓你參考.
開啓計算機
open -a Calculator
開啓 photoshop
open -a Adobe\ Photoshop\ CS4
用 Smultron 打開桌面上的 README.txt 檔案
open -a Smultron ~/Desktop/README.txt
打開某個網址
open http://liho.tw/
打開某張圖
open sexy.jpg
當然你可以把這些指令編輯道 .profile 裡面. 以方便日後開啓程式.
alias photoshop="open -a Adobe\ Photoshop\ CS4"
之後打 photoshop 就可以開啓photoshop.
遠端開啓的話, 也是一樣的方式. 只是記得在 System Preferences 開啓 Remote Login 的選項. 讓你自己能從遠端登入開啓圖形應用程式.
