xcrun(1) [osx man page]

xcrun
     xcrun -- run or locate development tools

SYNOPSIS
xcrun [-sdk SDK] -find <tool_name> xcrun [-sdk SDK] [-log] <tool_name> [<tool_arguments>] <tool_name> [<tool_arguments>] DESCRIPTION
xcrun provides a means locate or invoke coexistence- and platform-aware developer tools from the command-line, without requiring users to modify makefiles or otherwise take laborious or inconvenient measures to adopt Xcode's multiple tool chains. xcode-select is used to specify which installation of Xcode is used, and may be overridden by the DEVELOPER_DIR environment variable. The SDK defaults to the current OS SDK, and can be specified by SDKROOT environment variable or the -sdk flag (which takes precedences over SDKROOT). USAGE
The first usage returns the full path to the found tool_name. The second usage executes tool_name with the given tool_arguments. The last syntax is when xcrun replaces any of the standard UNIX developer tools (typically in /usr/bin). In this case, xcrun will use its tool name to locate the corresponding tool within evaluated DEVELOPER_DIR and SDK. If the tool is not named xcrun , tool_arguments are not parsed by xcrun. OPTIONS
-verbose display information about how the redirected path is constructed. -no-cache don't consult the cache when looking up values. In effect, causes the cache to be refreshed. -sdk SDK specifies which SDK to use. Overrides any SDKROOT set in the environment. -log print the full command line that is invoked. -find print the full path to the tool. ENVIRONMENT
DEVELOPER_DIR - specifies the search path for locating the current developer tools (overrides xcode-select default). SDKROOT - specifies the SDK to use; overriden by the command line -sdk flag. xcrun_log - same as specifying -log xcrun_nocache - same as specifying -no-cache xcrun_verbose - same as specifying -verbose DIAGNOSTICS
When xcrun is invoked with the name xcrun , the flags -log and -verbose are useful debugging aids. The flag -no-cache can be used to bypass cache lookup. When xcrun as taken the place of another tool, the arguments are those of the tool replaced, and the various xcrun flags can't be used. In this case, use the specific environment variables instead.

XCODE-SELECT(1) 					    BSD General Commands Manual 					   XCODE-SELECT(1)

NAME
xcode-select - Manages the active developer directory for Xcode and BSD tools. SYNOPSIS
xcode-select [-h|--help] [-s|--switch <path>] [-p|--print-path] [-v|--version] DESCRIPTION
xcode-select controls the location of the developer directory used by xcrun(1), xcodebuild(1), cc(1), and other Xcode and BSD development tools. This also controls the locations that are searched for by man(1) for developer tool manpages. This allows you to easily switch between different versions of the Xcode tools and can be used to update the path to the Xcode if it is moved after installation. Usage When multiple Xcode applications are installed on a system (e.g. /Applications/Xcode.app, containing the latest Xcode, and /Applica- tions/Xcode-beta.app containing a beta) use xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools. After setting a developer directory, all of the xcode-select provided developer tool shims (see FILES) will automatically invoke the ver- sion of the tool inside the selected developer directory. Your own scripts, makefiles, and other tools can also use xcrun(1) to easily lookup tools inside the active developer directory, making it easy to switch them between different versions of the Xcode tools and allow- ing them to function properly on systems where the Xcode application has been installed to a non-default location. OPTIONS
-h, --help Prints the usage message. -s <path>, --switch <path> Sets the active developer directory to the given path, for example /Applications/Xcode-beta.app. This command must be run with supe- ruser permissions (see sudo(8)), and will affect all users on the system. To set the path without superuser permissions or only for the current shell session, use the DEVELOPER_DIR environment variable instead (see ENVIRONMENT). -p, --print-path Prints the path to the currently selected developer directory. This is useful for inspection, but scripts and other tools should use xcrun(1) to locate tool inside the active developer directory. -r, --reset Unsets any user-specified developer directory, so that the developer directory will be found via the default search mechanism. This command must be run with superuser permissions (see sudo(8)), and will affect all users on the system. -v, --version Prints xcode-select version information. --install Opens a user interface dialog to request automatic installation of the command line developer tools. ENVIRONMENT
DEVELOPER_DIR Overrides the active developer directory. When DEVELOPER_DIR is set, its value will be used instead of the system-wide active developer directory. Note that for historical reason, the developer directory is considered to be the Developer content directory inside the Xcode applica- tion (for example /Applications/Xcode.app/Contents/Developer). You can set the environment variable to either the actual Developer con- tents directory, or the Xcode application directory -- the xcode-select provided shims will automatically convert the environment vari- able into the full Developer content path. EXAMPLES
xcode-select --switch /Applications/Xcode.app/Contents/Developer Select /Applications/Xcode.app/Contents/Developer as the active developer directory. xcode-select --switch /Applications/Xcode.app As above, selects /Applications/Xcode.app/Contents/Developer as the active developer directory. The Developer content directory is auto- matically inferred by xcode-select. /usr/bin/xcodebuild Runs xcodebuild out of the active developer directory. /usr/bin/xcrun --find xcodebuild Use xcrun to locate xcodebuild inside the active developer directory. env DEVELOPER_DIR="/Applications/Xcode-beta.app" /usr/bin/xcodebuild Execute xcodebuild using an alternate developer directory. FILES
