Typically on a cPanel host your access logs are kept in
/usr/local/apache/domlogs/username/incredigeek.com
Where username is your cPanel username and incredigeek.com is your website.
To view the logs you can use tail -f to follow the log.
tail -f /usr/local/apache/domlogs/username/incredigeek.com
You can also use grep to search the logs.
grep "text to search" /usr/local/apache/domlogs/username/incredigeek.com
The -h option allows you to connect to a remote host.

Create a file “list.txt” that contains all the URLs you want to download and launch the following command
for i in cat list.txt ; do wget ${i} && sleep $(( ( RANDOM % 120 ) +1 )) ; done
It’ll now run and after each link will wait a random amount of time up to 120 seconds before downloading the next link. Change the number as needed.
Change the 10 to however many seconds you need or want.
echo $(( ( RANDOM % 10 ) +1 ))
Example output
bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 10 bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 2 bob@localhost:~$ echo $(( ( RANDOM % 10 ) +1 )) 9 bob@localhost:~$
