Re: [Bug-wget] Any explanation for the '-nc' returned value?

[Tim Rühsen]

Hi,

from the man pages (--no-clobber):

########
           When running Wget without -N, -nc, -r, or -p, downloading the
same file in the same directory will result
           in the original copy of file being preserved and the second
copy being named file.1.  If that file is
           downloaded yet again, the third copy will be named file.2,
and so on.  (This is also the behavior with
           -nd, even if -r or -p are in effect.)  When -nc is specified,
this behavior is suppressed, and Wget will
           refuse to download newer copies of file.  Therefore,
""no-clobber"" is actually a misnomer in this
           mode---it's not clobbering that's prevented (as the numeric
suffixes were already preventing clobbering),
           but rather the multiple version saving that's prevented.
########

Regards, Tim
