What is your UMASK value? It's 0002, but I think I see the problem. In my testing, I was writing to a file that already existed, named "tmp.nc" that had 644 permissions, so nccopy wasn't changing the permissions, although it was overwriting the file. Apparently the bug is still there for creating a new file, it looks like it ignores the umask value in that case: $ umask 0002 $ nccopy test1.nc tmp.nc && ls -l tmp.nc -rw-rw-r-- 1 russ ustaff 108 Jun 27 13:41 tmp.nc $ nccopy -w test0.nc tmp.nc && ls -l tmp.nc -rw-rw-r-- 1 russ ustaff 104 Jun 27 13:41 tmp.nc $ rm tmp.nc $ nccopy -w test0.nc tmp.nc && ls -l tmp.nc -rwxrwxr-x 1 russ ustaff 104 Jun 27 13:42 tmp.nc Thanks for reporting this! We'll try to fix it for real, this time ... --Russ > On 06/27/2012 11:47 AM, Unidata netCDF Support wrote: > > Charlie, > > > > I should have also pointed out that the fix takes UMASK into account, > > rather than just setting the output file permissions to 644 ... > > > > --Russ > > > >>> What sets/controls the permissions on files nc_create()'d > >>> with NC_DISKLESS?
