DESCRIPTION

asql provides a simple console interface to allow a user to query the contents of an Apache logfile via an SQL interface. The shell features include: Persistent alias definitions. Command line completion Command history Simple scriptability
INTRODUCTION
The asql shell will create a temporary SQLite database based upon any number of Apache logfiles. This temporary database may then be interactively queried using common SQL syntax. To get started you should load your logfiles into the database: load /var/log/apache2/acces* (The tool will automatically decompress files which have been compressed with gzip or bzip2.) Once you've loaded at least one file you may run queries, for example: SELECT source,SUM(size) AS Number FROM logs GROUP BY source ORDER BY Number DESC, ip This example shows all the clients connecting to your webserver and the size of files/requests that they have downloaded in total. As you can see we've selected two columns "source" and "SUM(size)". To see which other columns are available you may execute the "show" command. Because parsing the Apache logfile(s) specified might be quite slow there is the option of dumping the temporary SQLite database to a known filename with the 'save' command. The analog to the save command is the 'restore' command, which will read in an existing SQLite database and allow future queries to be executed against it.
FILES
When the shell starts up it will read and intepret the initialisation file of ~/.asqlrc if it exists. Any commands present in that file will be executed prior to the launch of the interactive session. All aliases will be read and written to the file ~/.asql.aliases. All interactive history will be written to the file ~/.asql.
