1、 需求&解决方案
- 打开文件 或url（用默认应用程序）：
$ open fileName - 打开文件 或url（用指定应用程序）：
$ open -a appName fileName## appName 中若有空格，则用引号" 括起来 - 打开Finder，定位到当前位置:
$ open 'curDir'## PS: curDir 一定要用引号括起来 ， open . # 表示Finder打开当前文件夹

NAME
open - open files and directories
SYNOPSiS
open [-e] [-t] [-f] [-F] [-W] [-R] [-n] [-g] [-h] [-s _sdk]
[-b bundle_identifier] [-a application] _file. [-args arg1 ...]
DESCRIPTION
The open command opens a file (or a directory or URL), just as if you had
double-clicked the file's icon. If no application name is specified, the
default application as determined via LaunchServices is used to open the
specified files.
If the file is in the form of a URL, the file will be opened as a URL.
You can specify one or more file names (or pathnames), which are interpreted relative to the shell or Terminal window's current working direc-
tory. For example, the following command would open all Word files in the
current working directory:
open *.doc
Opened applications inherit environment variables just as if you had
launched the application directly through its full path. This behavior
was also present in Tiger.
The options are as follows:
-a application
Specifies the application to use for opening the file
-b bundle_identifier
Specifies the bundle identifier for the application to use when open-
ing the file
-e Causes the file to be opened with /Applications/TextEdit
-t Causes the file to be opened with the default text editor, as deter-
mined via LaunchServices
-f Reads input from standard input and opens the results in the default
text editor. End input by sending EOF character (type Control-D).
Also useful for piping output to open and having it open in the
default text editor.
-F Opens the application "fresh," that is, without restoring windows.
Saved persistent state is lost, except for Untitled documents.
-W Causes open to wait until the applications it opens (or that were
already open) have exited. Use with the -n flag to allow open to
function as an appropriate app for the $EDITOR environment variable.
-R Reveals the file(s) in the Finder instead of opening them.
-n Open a new instance of the application(s) even if one is already running.
-g Do not bring the application to the foreground.
-h Searches header locations for a header whose name matches the given
string and then opens it. Pass a full header name (such as NSView.h)
for increased performance.
-s For -h, partial or full SDK name to use; if supplied, only SDKs whose
names contain the argument value are searched. Otherwise the highest
versioned SDK in each platform is used.
-args
All remaining arguments are passed to the opened application in the
argv parameter to main(). These arguments are not opened or interpreted by the open tool.
EXAMPLES
"open '/Volumes/Macintosh HD/foo.txt'" opens the document in the default application for its type (as determined by LaunchServices).
"open '/Volumes/Macintosh HD/Applications/'" opens that directory in the Finder.
"open -a /Applications/TextEdit.app '/Volumes/Macintosh HD/foo.txt'"
opens the document in the application specified (in this case, TextEdit).
"open -b com.apple.TextEdit '/Volumes/Macintosh HD/foo.txt'" opens the
document in the application specified (in this case, TextEdit).
"open -e '/Volumes/Macintosh HD/foo.txt'" opens the document in TextEdit.
"ls | open -f" writes the output of the 'ls' command to a file in /tmp
and opens the file in the default text editor (as determined by LaunchServices).
"open http://www.apple.com/" opens the URL in the default browser.
"open 'file://localhost/Volumes/Macintosh HD/foo.txt'" opens the document
in the default application for its type (as determined by LaunchServices).
"open 'file://localhost/Volumes/Macintosh HD/Applications/'" opens that
directory in the Finder.
"open -h NSView" lists headers whose names contain NSView and allows you
to choose which ones to open.
"open -h NSView -s OSX10.12" lists headers whose names contain NSView in
the MacOSX 10.12 SDK and allows you to choose which ones to open.
"open -a Xcode -h NSString.h" quickly opens /System/Library/Frameworks/Foundation.framework/Headers/NSString.h in Xcode.
