how to map "dir" to "ls -al

learnfast · 03-09-2005, 06:03 AM

how can I map a command, e.g. when I type "dir" I want it to execute "ls -al | more"

"dir" already executes "ls" but the listing is not in color (I don't understand that either)

i'm using red hat 9.0 in text mode (init 3)

thanks

Hi,

alias dir='ls -al | more'

Take a look at the bash manpage (section: aliases).

Hope this helps.

Try

Code:

alias dir="ls -al --color=always | more"

excellent, that's exactly what I was looking for
and how can I save this alias so that it is available when I boot up / log in again?

thanks

where are the colors defined for the --color parameter?
directories seem to be dark blue, "mount" is white on red, some green, some aqua...
I checked "man ls" but it didn't tell me

thanks

To be able to use it everytime you boot the PC, add the aliast to your .bashrc file, for the colors, I don't know exactly what you want. If you don't want colors at all, add to the alias --color=none.
If you want to change colors, you must edit your /etc/DIR_COLORS file and put the colors you wish there for every time of archive.

how can I make an alias which accepts a parameter, e.g. as in msdos the %1 %2
so that I can say "dir b*"
something like this:
dir="ls -al --color=always %1 | more"

Add to the alais $1 so you end up with dir="ls -al --color=always $1 | more".
Note that you have to modify the alias if you want more parameters ($2 $3 and so on).
If you plan to use multiple parameters, I suggest you to make the alias as dir="ls -al --color=always" and add the | more afterwards if needed. as ls will take all the parameters you put as they are, you don't need to specify the $1 and more. Even though I can't imagine doing an ls with more that one parameter....

Hi,

Don't know if any of you noticed/know this, but dir is an excisting command (/usr/bin/dir).

Creating a alias/variable could give you unexpected outcome.

Just a 'heads-up'.

I got this to work:
dir="ls -al --color=always $1"

but this will not work:
dir="ls -al --color=always $1 | more"

does anyone know how to put the "more" command in the alias itself (I don't know why I would ever want ALL the files to just scroll on by and I only see the last ones, especially in text mode where I can't scroll back up)

thanks
