What’s the zypper command to change alias name of a repo?
This changes the descriptive name not the alias of a repo.


zypper mr -n new-name old-name
#2 
zypper nr old-name new-name

nr = rename repo
old-name = Old name of the repo (also can provide repo number, like 3 or 5 etc)
new-name = New name for the repo

#3

The man page says:

renamerepo (nr) <alias|name|#|URI> <new-alias>
Assign new alias to the repository specified by alias, name, number, or URI.
Example:
Rename repository number 8 to ‘myrepo’ (useful if the repo has some dreadful alias which is not usable on the command line).
$ zypper nr 8 myrepo
