228 You Are Here

If we want to see the size of a ﬁle or directory, when it was created and more, we can just add the

“long” option (-l)toourls -a command.

Try it. Type:

ls -al

There’s quite a bit more detail now. You can see the ﬁle creation date, its size, ownership, permissions

and more.

You don’t have to be in the directory whose contents you want to view, either.

Let’sseewhat’sinthe/etc directory by typing:

ls -al /etc

Here, you’ll get plenty of information about the contents of the /etc directory.

If you want to add color to your listing, just include the --color option.

ls -al --color /etc

To some, adding --color does more than add a splash of color; it gives a clue about the types of

ﬁles in a directory. For example, directories might all be a royal blue, program ﬁles would be green,

and so on.

If you like what you see, here’s how you can display the listing in color all the time. Brieﬂy, we’ll be

adding one line to the .bashrc ﬁle in our login directory.

The .bashrc ﬁle is used by your shell when you login (an example .bashrc ﬁle is shown in Figure

16.7).

Now before we go any further...

Remember that any changes you make to conﬁguration ﬁles can cause you a world of grief if you’ve

made a mistake and you don’t have a backup copy of that ﬁle.

To make a backup copy, make sure you’re in your login directory and in an xterm window, type:

cd ˜

to get to your login directory. Then copy the .bashrc ﬁle, keeping it in the same directory, but with

a name like .bashrc2.

cp .bashrc .bashrc2
