MacOS – Command Line Tools fail to install OS X Lion 10.7.3 Xcode 4.3

You can install the command line tools within XCode.

Open XCode and navigate to the preferences.

From here you have to go to the Downloads-Section. Here you can see the ability to install the command line tools:

EDIT: I can see the right command line tools on the download-page from Apple:

Wish I could claim credit for this one, but I found it buried in https://github.com/chcokr/osx-init/blob/master/install.sh

This worked on my 10.10 headless VM without a logged in UI. Updates applied for compatibility with at least 10.9-10.14

touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress;
PROD=$(softwareupdate -l |
  grep "\*.*Command Line" |
  head -n 1 | awk -F"*" '{print $2}' |
  sed -e 's/^ *//' |
  tr -d '\n')
softwareupdate -i "$PROD" --verbose
rm /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress

This presumes you only have 1 result to softwareupdate -l | grep "\*.*Command Line" - if this returns multiple versions, you might need more specific logic. (I dont have a repro case)

one variation that seems to work (limited testing) on 10.10-10.14 (10.9 doesn't return an osx version number in the cli tools name..so this doesn't work there):

PROD=$(softwareupdate -l |
 grep "\*.*Command Line.*$(sw_vers -productVersion|awk -F. '{print $1"."$2}')" |
 head -n 1 | awk -F"*" '{print $2}' |
 sed -e 's/^ *//' |
 tr -d '\n')

a few example results:

* Command Line Tools (OS X Mavericks)-6.2
* Command Line Tools (OS X 10.10) for Xcode-7.2
* Command Line Tools (macOS El Capitan version 10.11) for Xcode-8.2
* Command Line Tools (macOS High Sierra version 10.13) for Xcode-10.1
* Command Line Tools (macOS Mojave version 10.14) for Xcode-10.1
