wget -O - http   yoursite com tasks php  gt  dev null 2 gt  amp 1   That should work for you  Just have a wget script that loads the page   Using -O - means that the output of the web request will be sent to STDOUT  standard output   by adding  gt  dev null we instruct standard output to be redirect to a black hole   by adding 2 gt  amp 1 we instruct STDERR  errors  to also be sent to STDOUT  and thus all output will be sent to a blackhole   so it will load the website  but never write a file anywhere

You don t need the redirection  use only            wget -qO  dev null http   yoursite com tasks php

wget --quiet https   example com file --output-document  dev null  I find --quiet clearer than -q  and --output-document  dev null clearer than -O -  gt   dev null
