Question: I want to create two different aliases to the same command without repeating myself. How can I do it in bash? For example, I want listlong and longlist to both be aliases to "ls -al".

Answer: 
```
alias {listlong,longlist}="ls -al"

```

That should do it.
```
alias listlong='ls -al'
alias longlist=listlong

```

And further changes of the alias `listlong` reflect on `longlist` too.
