>                 Key: KARAF-5629
>                 URL: https://issues.apache.org/jira/browse/KARAF-5629
>             Project: Karaf
>          Issue Type: New Feature
>          Components: karaf-shell
>    Affects Versions: 4.1.5, 4.2.0.M2
>            Reporter: Lijun Liao
>            Assignee: Guillaume Nodet
>            Priority: Minor
>             Fix For: 4.2.0
>
>
> Take the following example:
> {code:java}
> if {"$v" equals "a"} {
>   do something a
> } {
>   if {"$v" equals "b"} {
>     do something b
>   } {
>     if {"$v" equals "c"} {
>       do something c
>     } {
>       do something others
>     }
>   }
> }
> {code}
> By introducing the commands shell:elif and shell:else, this can be simplified as follows:
> {code:java}
> if {"$v" equals "a"} {
>   do something a
> } elif {"$v" equals "b"} {
>   do something b
> } elif {"$v" equals "c"} {
>   do something c
> } else {
>   do something others
> }
> {code}
