Wget – is the non-interactive network downloader, and you can set it up to download without retrying / making any retries with the following option:
-t number / --tries=number: Set number of retries to number. Specify 0 or ‘inf’ for infinite retrying. The default is to retry 20 times, with the exception of fatal errors like “connection refused” or “not found” (404), which are not retried.
It is usually also helpful to set up a timeout for requests which may take a long time:
-T seconds / --timeout=seconds: Set the network timeout to seconds seconds. This is equivalent to specifying ‘–dns-timeout’, ‘–connect-timeout’, and ‘–read-timeout’, all at the same time. When interacting with the network, Wget can check for timeout and abort the operation if it takes too long. This prevents anomalies like hanging reads and infinite connects. The only timeout enabled by default is a 900-second read timeout. Setting a timeout to 0 disables it altogether. Unless you know what you are doing, it is best not to change the default timeout settings.
All timeout-related options accept decimal values, as well as subsecond values. For example, ‘0.1’ seconds is a legal (though unwise) choice of timeout. Subsecond timeouts are useful for checking server response times or for testing network latency.
