split-logfile - Split combined virtual hosts access log into one file per
split-logfile < logfile
This script will take a combined Web server access log file and break its
contents into separate files. It assumes that the first field of each line is
the virtual host identity (put there by "%v"), and that the logfiles
should be named that+".log" in the current directory.
The combined log file is read from stdin. Records read will be
appended to any existing log files.
