Duplicity doesn't like max open files setting on Mavericks

Question

I use duplicity to backup some files. I'm now trying to restore to my Mac to test the backup, but get the following error:

> duplicity [email protected]/backup_dr ~/restored_files
Max open files of 256 is too low, should be >= 1024.
Use 'ulimit -n 1024' or higher to correct.

So I try:

sudo ulimit -n 1024

And it seems fine, then run:

> ulimit -a
...
open files                      (-n) 256
...

How do you actually get the limit to change? I've Google'd with no luck :(

Answer 1

I had the exact same problem. Turns out this works under bash, but not in tcsh.

Answer 2

Try ulimit -n 1024 without sudo. For some reason it didn't work with sudo for me. If it says Operation not permitted try closing and opening another terminal.
