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..

This question came from our site for professional and enthusiast programmers.

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 \;
