# # This script was taken in its entirety from:

# https://github.com/rtrouton/rtrouton_scripts/
|
|
#
|
|
# This script will download and install the Xcode command line
|
|
# tools on Macs running 10.7.x and higher.

|
|
# How the script works:
|
|
#
|
|
# On 10.9.x and 10.10.x:
|
|
#
|
|
# 1. Creates a placeholder file in $tmpDir. This file's existence is checked by the
|
|
# softwareupdate tool before allowing the installation of the Xcode command line tools.
|
|
#
|
|
# 2. Runs the softwareupdate tool and checks for the latest version of the Xcode command
|
|
# line tools for the OS in question.
|
|
#
|
|
# 3. Uses the softwareupdate tool to install the latest version of the Xcode command
|
|
# line tools for the OS in question.
|
|
#
|
|
# 4. Removes the placeholder file stored in /tmp.
|
|
#
|
|
#
|
|
# On 10.7.x and 10.8.x:
|
|
#
|
|
# 1. Uses curl to download a disk image containing the specified Xcode Command Line
|
|
# Tools installer from Apple's web site
|
|
#
|
|
# 2. Renames the downloaded disk image to cltools.dmg.
|
|
#
|
|
# 2. Mounts the disk image silently in $tmpDir. Disk image will not be visible to any
|
|
# logged-in user.
|
|
#
|
|
# 3. Installs the Xcode Command Line Tools using the installer package stored on the
|
|
# disk image
|
|
#
|
|
# 4. After installation, unmounts the disk image and removes it from the Mac in question.
