I type in cdd directory and what that does is cd directory and then ls?

1A note (though others have mentioned) aliases can not have arguments. You need a function. – Rich Homolka – 2011-05-20T23:17:38.920

1Why don't you use ls directory instead? – user unknown – 2012-01-13T07:20:22.767

It'd be easier to make a function:

cdd () 
{
    cd $1
    ls
}

Of course, you can name the function whatever you like. Put it in your .bashrc or .profile or whatever it is on your system.

does that automatically mkae cdls an alias? – funk-shun – 2011-05-19T18:48:37.307

3@funk-shun it makes cdd a function, which in practice acts almost exactly like an alias would. Functions are more powerful and take arguments, though. – Rafe Kettler – 2011-05-19T18:49:48.133

so i take it $2 refers to the second argument in a command call? -r in the case of ls -C -r? – funk-shun – 2011-05-19T18:53:30.813

@funk-shun yes. – Rafe Kettler – 2011-05-19T18:54:20.253

You want to use a function that you'll put in your .bashrc (or .bash_profile, or whatever):

cdd(){
  to=$1
  cd ${to}
  ls
}

Once you put this in your appropriate file, you can use cdd <directory> just like an alias.

1This will break on directories with spaces in them – Daenyth – 2011-05-19T19:55:57.813

Just like the other function examples, but this one will work with directories with spaces, without needing to escape the spaces.

cdd() {
    cd "$*"
    ls
}

alias dirXandLs='cd directory; ls'

I bet you really want to make directory be an argument, i.e. $1. can't do that with aliases.

I hope that helps.

I think here is your answer. you can add this function to your .bashrc file:

function cd(){ builtin cd "$*" && ls }
