Passing Environment Variables

In this blog I show you how to set ssh and sudoers for passing environment variables on Linux machines. We use it to set the name of the administrator who commits the changes to the repository (see gitkeeper).

Example

	tomas@client# env | grep GIT_AUTHOR_NAME
	-> GIT_AUTHOR_NAME=Tomas Jurman
	ssh tomas@server
	tomas@server# env | grep GIT_AUTHOR_NAME
	-> GIT_AUTHOR_NAME=Tomas Jurman
	tomas@server# sudo -i
	root@server# env | grep GIT_AUTHOR_NAME
	-> GIT_AUTHOR_NAME=Tomas Jurman
