hope you can help me, I'm looking for a command to let me copy all files above 500kB in my directory one to directory 2..

Basically I have a lot of Images in directory1 and would like to copy all images larger than 500kB to my other folder directory2..

Do you want to copy, move, or make a link? You probably want to either move or make a (hard) link. Copying is rarely necessary. – William Pursell Nov 26 '12 at 19:34
    
Well, I want to copy, because thats what i want. My folder of images is made by foremost, so I want to keep the collection as a whole untill later... – Qw_freak Nov 26 '12 at 22:08
    
I notice that I am getting some votes down, why is this? Should i have elaborated that I had tried various things with xargs, which did'nt work before asking my question? – Qw_freak Nov 27 '12 at 7:38

You can use find thus:

find directory1 -type f -size +500k -exec cp -nv {} directory2/ \;
  • -v : verbose copy (you see what's copying)
  • -n : noclobber (might not be available to your cp version): do not overwrite an existing file (just in case).

Thanks man, it really helped, I had like a million images ranging from 1kB to 7mB, and 99% of those where >500kB... They where collected by foremost because i acidently deleted an image folder... – Qw_freak Nov 26 '12 at 22:10
    
Why the Backslash semicolon in the end? – Qw_freak Nov 27 '12 at 7:38
    
@Qw_freak because for bash, a semicolon is a separation character, so if not escaped, it would not be sent to find. But find needs to have a semicolon to know where the -exec option ends. We must hence escape it. – gniourf_gniourf Nov 27 '12 at 9:49

This should do it:

find directory1 -type f -size +500k -exec cp {} directory2 \;
