-Q quota
--quota=quota
Specify download quota for automatic retrievals. The value can be specified in bytes (default), kilobytes (with k suffix), or megabytes (with m
suffix).
Note that quota will never affect downloading a single file. So if you specify wget -Q10k ftp://wuarchive.wustl.edu/ls-lR.gz, all of the ls-lR.gz
will be downloaded. The same goes even when several URLs are specified on the command-line. However, quota is respected when retrieving either
recursively, or from an input file. Thus you may safely type wget -Q2m -i sites---download will be aborted when the quota is exceeded.
Setting quota to 0 or to inf unlimits the download quota.
