The command "install-tl -portable" is used to install TeX Live, a widely used software distribution for the TeX typesetting system, in a portable mode.

The "install-tl" command is the main command to install TeX Live. When combined with the "-portable" option, it specifies that the installation should be done in a portable manner.

Installing TeX Live in portable mode means that the entire TeX Live distribution, including all packages, binaries, and configuration files, will be installed within a single directory or folder. This allows you to easily move the TeX Live installation to a different location or even to a different computer without the need to run an installer or modify system settings.

The "install-tl" command with the "-portable" option is typically used when you want to have a self-contained TeX Live installation that can be carried around on a USB drive or transferred between different systems without any external dependencies.

To use this command, you need to have TeX Live distribution files available on your system. These files can be obtained from the official TeX Live website. Once you have downloaded the distribution files, you can run the "install-tl -portable" command in a terminal or command prompt to start the installation process.

After the installation is complete, you will have a portable TeX Live installation that can be used by invoking the appropriate commands or utilities, such as "pdflatex" or "latex", depending on your needs.
