loris has asked for the wisdom of the Perl Monks concerning the following question:
Hello Knowledgable Ones,
I have around 40 logfiles of about 15 MB each. Around 30 processes write willy-nilly into these files, whereby each line contains text which identifies the process. I would like to untangle the log files to produce a single file for each process.
Naively I could try to slurp all the logfiles and then just use grep or split to get the process ID and then write to the appropriate new log file. However, I suspect that I might have some memory issues slurping all the data, but apart from that I would like to know what would be a more scalable approach.
