When the cron job executes wget
command (fetches URL resource), it creates a new file every time. It doesn’t overwrite the old downloaded file, but appends a number so by time, there will be thousands of files unless you tweak your crontab to suppress the output.
Open the crontab in your favorite text editor:
$ vim /etc/crontab
Add /dev/null at the end of the line to enable redirection of the wget’s output:
* * * * * wget https://fullstack-tutorials.com/resource >/dev/null 2>&1
>/dev/null
tells the cron to send output (STDOUT) to /dev/null, which destroys the useless data2>&1
tells the cron to send errors (STDERR) to the same target than the normal output (STDOUT)After this operation, no more downloaded files are created. Please note that also errors are suppressed, so in case of error, there is no track of it.
