The Logtools package contains a number of programs for managing log files (mainly for web servers).
clfmerge will merge a number of Common Logfile Format web log files into a single file while also re-ordering them in a sliding window to cope with web servers that generate log entries with the start-time of the request and write them in order of completion.
logprn operates like tail -f but will (after a specified period of inactivity) spawn a process and write the new data in the log file
to it’s standard input.
clfsplit will split up a single CLF format web log into a number of files based on the client’s IP address.
funnel will write it’s standard-input to a number of files or processes.
clfdomainsplit split a CLF format web log containing fully qualified URLs (including the host name) into separate files, one for each host.
logtools-0.13e.tgz – made it compile with the latest STL, and made it not default to “verbose” mode.
