Every now and then, one may wish to have had a simple script to check out or
update all the github repos you have, at once, using a single command.
This can be for the reason of backups, or simply, check out new ones that you don’t have etc,
or, keeping a local up-to-date copy of everything.
Well, I wrote a similar little script some time back for BitBucket.
(http://emberlabs.tech/2023/05/08/easily-mirror-a-bitbucket-repo/)
This should work just fine on pretty much any Linux or Mac install (or similar with a bash).
Nuf of the talk! Show me the code!! =D
