Your question is not so clear. But I guess what you need is an alias:-
Code:
alias startvm='startguest'

It doesn't work

Code:
#!/bin/bash
xx()
{
        echo "xx"

}

alias yy='xx'
yy

It will report

Code:
./xx.sh: line 9: yy: command not found

Oh I got now what you are asking. You can use eval for this:
Code:
#!/bin/bash
xx()
{
    echo "xx"
}
yy=xx
eval $yy

Thanks, if alias work that's perfect
I have a script is
Code:
xx()
{
something
}
zz()
{
something 
}

main()
{
aa
bb
xx
}

in another script I want to call "main" BUT, the xx I want to be zz, and don't want to change main() function anything, here you are use eval $xx
