One way would be to use find combined with realpath.

find /media/data -exec realpath "{}" \;

That's recursive.  If you want only that one directory, limit how deep
it may go:

find /media/data -maxdepth 1 -exec realpath "{}" \;

If that's too long to type out each time, you can make a shell alias or
function that accepts the path as an option and then passes that to find.


To get the format as the OP displayed it, you may also need to pipe
the output through sort.

But bear in mind that, using realpath, the output could have files
rooted all over the place (eg try with /etc/systemd/), so after
sorting them, files that you thought would appear together may well
get separated.

man find   will make a good long read during the Polar Vortex!

something else that you could use is 'locate'

it's on most systems nowdays and it updates each night from cron.  it's not as 
cpu intensive and you can update is quickly with 'updatedb'.

if you're just searching removable media, as in your /media/... example then 
find would be better.

i prefer locate to find when searching the entire system.

"find" is what I was looking for.
Browsing the man page suggests I can even select which lines to 
print - i.e. I'm only really in files of form *.html .

Thanks again.

I don't recall now when I first learnt about the find command.  Now I
use it all the time.  The Unix Power Tools book
(http://shop.oreilly.com/product/9780596003302.do) has a chapter on the
find command.  If you have access to an O'Reilly Safari account, you
could browse through it.

I can't say for sure that ls can't do this, but if I wanted that, I'd
use find.

'find /path/to/directory' produces a list of all nodes (files,
directories, or otherwise) in the specified directory, in exactly the
format you indicate.

Generally, if you want to do something recursively across directories in
an *nix environment, find is the tool to use. Some tools do have
recursiveness options of their own, and occasionally those options are
easier to use or provide better functionality, but in most cases you're
better off going to find as a first resort.

[Newbie] Can ls command format output my way?

[Richard Owlett]

ls -R /media/data produces the content but not the NEEDED format.

I want a list like:
/media/data/dir1/filea
/media/data/dir1/fileb
/media/data/dir1/subdir1/filex
/media/data/dir1/subdir1/filey
/media/data/dir1/subdir1/filez
/media/data/dir2/filea
/media/data/dir2/fileb
/media/data/dir2/subdir1/filex
/media/data/dir2/subdir1/filey
/media/data/dir2/subdir1/filez
et cetera

I don't wish anything but full path to all files in a top level 
directory.
