# Provide a simple shell extension to save and load govc
|

|
|
# environments to disk. No more running `export GOVC_ABC=xyz`
|
||
|
|
# in different shells over and over again. Loading the right
|
||
|
|
# govc environment variables is now only one short and
|
||
|
|
# autocompleted command away!
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# * Source this file from your `~/.bashrc` or running shell.
|
||
|
|
# * Execute `govc-env` to print GOVC_* variables.
|
||
|
|
# * Execute `govc-env --save <name>` to save GOVC_* variables.
|
||
|
|
# * Execute `govc-env <name>` to load GOVC_* variables.
