I am trying to update Command line tools on my mac osx.
~ softwareupdate --list

Finding available software
Software Update found the following new or updated software:
* Command Line Tools (macOS El Capitan version 10.11) for Xcode-8.2
Command Line Tools (macOS El Capitan version 10.11) for Xcode (8.2), 150374K [recommended]
* iTunesX-12.5.5
iTunes (12.5.5), 263476K [recommended]
But when I run the update command, I get this error:
softwareupdate -i Command Line Tools (macOS El Capitan version 10.11) for Xcode-8.2
zsh: number expected
This doesn't work either:
softwareupdate -i Command Line Tools
Software Update Tool

Command: No such update
Line: No such update
Tools: No such update
No updates are available.
What is the exact string I should specify after sofwareupdate -i?
回答1:
Run softwareupdate -i "Command Line Tools (macOS El Capitan version 10.11) for Xcode-8.2". The quotes are important.

For future travelers, here's a version-agnostic approach. First, run softwareupdate --list. This will probably take a couple of minutes. When it's done, you'll see a bulleted (with an asterisk) output like this:
$ softwareupdate --list
Software Update Tool
Finding available software
Software Update found the following new or updated software:
* Command Line Tools (macOS High Sierra version 10.13) for Xcode-10.1
Command Line Tools (macOS High Sierra version 10.13) for Xcode (10.1), 190584K [recommended]
Find the bullet that refers to the Xcode command line tools. Copy that entire line (except the asterisk...). In the above case, you would copy: Command Line Tools (macOS High Sierra version 10.13) for Xcode-10.1
Then, run the install command (as shown by Brendan Shanks) with what you copied inside quotes:
softwareupdate -i "Command Line Tools (macOS High Sierra version 10.13) for Xcode-10.1"

I'm going to answer a slightly different question here, because this question came up when I searched for a solution to my problem. Hopefully it'll help someone (and it'll surely help me next time I run into the same issue).
I wanted to upgrade the command line tools from version 8 to 9. The App Store didn't suggest this upgrade, and neither did softwareupdate --list.
xcode-select --install
installed the new version of the tools. But clang --version still gave 8.0.0 as the version number. xcode-select -r and rebooting didn't solve this issue.
xcode-select -p returned /Applications/Xcode.app/Contents/Developer, and clang --version reported an installation directory under there. I thought I'd start over again.
sudo rm -rf /Applications/Xcode.app
deleted version 8 of the tools. But xcode-select --install said the command line tools were already installed.
sudo xcode-select -r
Now, sudo xcode-select -p returns /Library/Developer/CommandLineTools/.
It seems that the problem was that the new version of the tools are installed to a different directory, and xcode-select -r is not clever enough to find the latest version.

I ran the same command with sudo and that did the trick.
sudo softwareupdate -i "Command Line Tools (macOS El Capitan version 10.11) for Xcode-8.2"

I faced similar problem on MacOS Mojave version 10.14.3 with Xcode 10.3 installed. The real problem was, when I installed the Xcode 10.3, I deleted the "Xcode-beta.app" first and then installed the new version. Therefore, when I tried installing CLion for C++ development and configuring it, CMake gave me error And Updating Command Line Tool didnt work for me:
softwareupdate -i "Command Line Tools (macOS Mojave version 10.14.3) for Xcode-10.3"
and showed me this response in terminal
Software Update Tool
Command Line Tools (macOS Mojave version 10.14.3) for Xcode-10.3: No such update
No updates are available.
Then I tried to check the version of Clang using:
clang --version
And the response lead me to the real problem i.e. Active Developer path was still pointing to Old version of Xcode that I had already deleted.
xcrun: error: active developer path ("/Applications/Xcode-beta.app/Contents/Developer") does not exist
Therefore, I switched the active developer path to latest Xcode App installed using:
sudo xcode-select --switch /Applications/Xcode.app
And everything worked like a charm automatically.
