 ## Using lnav
 [lnav](https://lnav.org/) is a tool to navigate log files that provides several advanced query features. The default AWS S3 log files are not recognized by `lnav` but if you drop the first two columns of the files then they are recognized:
 
 ```
-for file in ./s3_log_data/*; do awk '{print substr($0, index($0, $3))}' $file > $file.log done
+for file in ./s3_log_data/*; do awk '{print substr($0, index($0, $3))}' $file > $file.log; done
