in reply to Question about the most efficient way to read Apache log files without All-In-One Modules from CPAN (personal learning exercise)
I've never personally seen an apache logfile, care to post a link to one for an example? I am positive in as long as you can understand the format of the file, then it can be parsed. Pack and Unpack work great, i use it in almost every script i write, though i deal alot with binary information, and it is easier for me to parse through it if i can see the hexadecimal representation of the data.
Either way, post that log file and see if we can figure out how it is formatted ;D
EDIT: Though usually, if there is a module for it, then that will most likely be the fastest way to parse said file 99% of the time.
