Help with sorting folders

ncube22 · 12-19-2012, 09:17 AM

Linux Newbie.. So pardon my ignorance.
I need to sort folders for "each year" based on the ls -ltr cmd below and copy them to a diff path.
Ex: ls -ltr
drwxr-xr-x 2 mqm mqm 80 Mov 3 2007 38
drwxr-xr-x 2 mqm mqm 80 Dec 2 2007 21
drwxr-xr-x 2 mqm mqm 80 Jan 3 2008 01
drwxr-xr-x 2 mqm mqm 80 Jan 3 2008 82
drwxr-xr-x 5 mqm mqm 1024 Dec 3 2009 24
drwxr-xr-x 2 mqm mqm 80 Jan 3 2010 21
drwxr-xr-x 2 mqm mqm 80 Nov 3 2010 613
drwxr-xr-x 5 mqm mqm 1024 Feb 3 2011 493
drwxr-xr-x 5 mqm mqm 1024 Oct 4 2012 349

Hello ncube22, welcome to LQ,

is this homework? As per our forumrules we do not each other's homework.

Could you please explain, what you have achieved so far?
Have you already written some code? please post it here.
Which tools/programs do you want to use?

Markus

Dude. Chill out. This ain't a homework, so people have to list out their achievements to post a qn and look for a solution/help. Wow.
Didn't know that.. If you can help do so or else please move on with you life.

Later !

How is the sorting you want different from what ls -tr provides? Please understand that directories are stored in no particular order on disk; only the presentation of the order can vary. When userspace code gets a list of files or directories, they are read in whatever order the kernel/filesystem chooses. The application (like ls, for example) then sorts the list (or not) according to its own purpose. The same goes for copying. When you write the files or directories, they will be stored in an arbitrary arrangement not controllable by you.

BTW, it is customary for people to demonstrate that they are actually trying to accomplish their objective on their own, and not simply using LQ as a source of free workers.

Sorting on basis of yrs value can be done as:

Code:

ls -la | sort -n -k 7

You can then create a small script and copy/move selected files to another place.

Ciao!

No need to be so harsh. As previously pointed out - if you show some effort and tell us at which point you're stuck or what exactly puzzles you, you will receive answers more suitable to your needs. Being it homework or not.

Regarding your question, you can start from something like:

Code:

for dir in */
do
  destination=/path/to/destination/$(date -r $dir +%Y)
  mkdir -p $destination && cp -a $dir $destination
done

This will create yearly directories under /path/to/destination based on the timestamp of the directories and copy them accordingly. Not sure if it's really what you're looking for. Hope it helps, anyway.
