Using aliases with nohup

Question

Why doesn\'t the following work?

$ alias sayHello=\'/bin/echo \"Hello world!\"\'
$ sayHello 
    Hello world!
$ nohup sayHello
    nohup: appending output to `n         


        

Answer 1

If you look at the Aliases section of the Bash manual, it says

The first word of each simple command, if unquoted, is checked to see if it has an alias.

Unfortunately, it doesn't seem like bash has anything like zsh's global aliases, which are expanded in any position.
