xcode-select

Manages active developer directory for Xcode and BSD tools.

xcode-select [-h|--help] [-s|--switch path] [-p|--print-path] [-v|--version]

Controls the location of the developer directory used by xcrun, xcodebuild, cc, and other Xcode and BSD development tools as well as the locations that are searched for by man.

Allows switching between different versions of the Xcode tools and can be used to update the path to the Xcode if it is moved after installation.

When multiple Xcode applications are installed (e.g. /Applications/Xcode.app, containing the latest Xcode, and /Applications/Xcode-DP.app containing a developer preview) use xcode-select --switch path/to/Xcode.app to specify the Xcode for command line tools.

xcode-select provided tool shims (see FILES) invoke the version inside the selected directory. Your own scripts, makefiles, and other tools can use xcrun to easily lookup tools in the developer directory, allowing them to function properly where the Xcode has is installed to a non-default location.

-s path
--switch path
Sets the active developer directory. Requires root. Affects all users .
for only the current shell session, use $DEVELOPER_DIR=
-r
--reset
Unsets user-specified directory. Requires root. affects all users
-p
--print-path
--install Opens a dialog to request installation of the command tools.
xcode-select: note: install requested for command line developer tools
"Install now?"
-v
--version
as of 3/18/16 xcode-select version 2343.
-h
--help
 

$DEVELOPER_DIR
Overrides the active developer directory.

Examples

Select /Applications/Xcode.app/Contents/Developer as the active developer directory.
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
Yosemite use xcode-select --switch path/to/Xcode.app

select /Applications/Xcode.app/Contents/Developer as the active developer directory.
The content directory is inferred .

xcode-select --switch /Applications/Xcode.app

Run xcodebuild from the active developer directory.
/usr/bin/xcodebuild

Use xcrun to locate xcodebuild inside the active developer directory.
/usr/bin/xcrun --find xcodebuild
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild

Execute xcodebuild using an alternate developer directory.

env DEVELOPER_DIR="/Applications/Xcode-DP.app" /usr/bin/xcodebuild

FILES

to find or run arbitrary commands from the active developer directory. See xcrun /usr/bin/xcrun

Run the matching Xcode tool from with the active developer directory. /usr/bin/agvtool /usr/bin/desdp /usr/bin/ibtool /usr/bin/ictool /usr/bin/instruments /usr/bin/iprofiler /usr/bin/opendiff /usr/bin/sdef /usr/bin/sdp /usr/bin/xcodebuild /usr/bin/xed Run the matching BSD tool from with the active developer directory, specify /usr/bin/ ie
