Use webalizer as a command line tool to analyse the apache2 access logs.
After installing webalizer create a folder into which the results will be saved (as HTML), using mkdir, and then cd (change directory) into the folder.
Next, collect together all of the apache logs you can access using
zcat for compressed files and
cat for text files, redirecting the output to the
file tmp.log.
zcat /var/log/apache2/access*.gz > tmp.log
cat /var/log/apache2/access.log.1 /var/log/apache2/access.log >> tmp.logWe sort the lines in tmp.log, saving to
access.log, so that we don’t confuse the
webalizer. This command line comes from

sort -u -t ' ' -k 4.9,4.12n -k 4.5,4.7M -k 4.2,4.3n -k 4.14,4.15n -k 4.17,4.18n -k 4.20,4.21n tmp.log > access.logNow run the webalizer over the sorted access.log
file targeting the output, using -o, to be the current working
