Piping reference for "INSTALL=y sh"

I came around this

With the following command for shell:

curl https://raw.github.com/visionmedia/git-extras/master/bin/git-extras | INSTALL=y sh

Which results in:

mkdir: cannot create directory `/share': Permission denied
make: *** [install] Error 1
No manual entry for git-extras

I am curious to know about this piping for 'INSTALL', which my short googling I only found the example in this github. I would like to know how it could be run with sudo and a reference to this sort of piping.

Solution 
  • INSTALL=y sh

    means to run the sh program with the environment variable INSTALL set to y. You can use sudo as follows:

    curl https://raw.github.com/visionmedia/git-extras/master/bin/git-extras | sudo INSTALL=y sh
