That command will cat the output of /var/log/httpd/access and pipe its
output to the grep command, which will "grep" from the term .ida and the
pipe the output of grep to the wc -l command (word count, # of lines)

Basically is searches for all occurances of the term ".ida" in the httpd log
and then displays that number

Basic unix 101
