Bash function

Shell Programming and Scripting

startvm()
{
   startguest
}

Is there a way use one line to get this ? actually I want startvm=startguest

Your question is not so clear. But I guess what you need is an alias :-

alias startvm='startguest'

It doesn't work

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

}

alias yy='xx'
yy

It will report

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

Oh I got now what you are asking. You can use eval for this:

#!/bin/bash
xx()
{
    echo "xx"
}
yy=xx
eval $yy

Thanks, if alias work that's perfect
I have a script is

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

Just out of curiosity... what are you trying to achieve here!!

why don't you call these functions as it is?
