alias

is it possible to setup an alias for cd to automatically give me an ls?

for example: alias -x cdls="cd $whatever:ls -la"

alias cdls='cd $whatever; ls -la'

that will work for any directory? so now if I put cdls /home its the same as
$cd /home
$ls -la

correcT?

Yes.

To be more precise, if you set your alias like this:

Code:

alias cdls='cd $1; ls -la $1'

the $1 means the first argument given to `cdls` (which is the path)

so if you type:

Code:

cdls /tmp

the shell interprets it as:

Code:

cd /tmp; ls -la /tmp

also to make this permanent add the alias line to your ~/.bashrc file.

I have since found that the above doesn't actually work as intended, apparently aliases don't work with arguments inside the command string; therefore you must use shell functions instead.

Type this in your ~/.bashrc instead:

Code:

cdls() {

    cd $1;
    ls -la $1

}
