Help with bash - ls command

Hi,

I would like to write up a command (this is the default version):

ls -o -h --color=auto --group-directories-first

that turns default output:

is it possible? I know very little sed, and this look troublesome because of tabs and different string sizes...

Then you should add a little awk, which is perfect when dealing with rows. Google might give you more information, try the search term "awk sort rows".

Do not do this by modifying ls's output. Use GNU stat(1) or the printf option to find(1).

ls -o -h --color=auto --group-directories-first | awk '{if (NF == 2) print; else print sprintf("%-20s",$8),$2,$3,$4,$5,$6,$7,$1;}'

Specifying column widths need more love

Here's a way:

 ls -o -h --color=auto --group-directories-first | awk -F " " '{ print $8" "$2" "$3" "$4" "$5" "$6" "$7" "$1}' | column -t
