A good example is [this post](https://kudithipudi.org/how-to-sort-apache-web-logs-for-hits-by-unique-ip-addresses/) about using grep and sort to find the unique hits to a website. Here is another way to do it using [grep](http://en.wikipedia.org/wiki/Grep?ref=kudithipudi.org) and [awk](http://en.wikipedia.org/wiki/AWK?ref=kudithipudi.org). Say the log file you are analyzing is in the format below and you need to get the unique number of BundleIDs ``` 2013-02-25 12:00:06,684 ERROR [com.blahblah.sme.command.request.CustomCommand] Unable to execute AssignServiceCommand, request = ‘1234565080' ``` you can use grep and awk to find the number of times a unique bundleID appears by running ``` grep -i bundleID LOG_FILE_NAME | awk ‘{ split ($11,a,">"); print a[6]}’ | sort | uniq -c | sort -rn ``` breaking down the commands **grep -i** : tells grep to only show the lines from the file (LOG\_FILE\_NAME) containing the text bundleID and makes the search case insensitive **awk ‘{ split ($11,a,”>”); print a\[6\]}’** : tells awk to grab the input from grep and take the 11th item (by default awk separates content with a space) and split the string into an array (a) using > as a delimiter. And finally print out the value of the array a’s sixth member **sort** : sorts the output from awk into ascending order **uniq -c** : takes the output from sort and counts uniq items **sort -qn** : takes the output from uniq and does a reverse order sort The output looked like this ``` 173 5080
