perl, Reading into a two-dimensional array from STDIN

Reading into a two-dimensional array from STDIN

Author	Message
Superma #1 / 3	Reading into a two-dimensional array from STDIN Greets and Salutes, I would like to read into a two-dimensional array after getting the input from parsing an Apache log. I start with lines (in the access_log) which look like this: 203.135.248.191 - - [27/Mar/2002:12:20:56 -0500] "GET /sunysb/swebsock/0014879/0815702/SUNYSB/center.cml?12+5+x+x+x+x+x+x HTTP/1.0" 200 9939 203.135.248.191 - - [27/Mar/2002:12:21:13 -0500] "GET /sunysb/swebsock/0014879/0815702/SUNYSB/confhome.cml?19+6+225+x+x+x+x+x HTTP/1.0" 200 18127 perform some grep(ing) and awk(ing) to get multiple occurrences of: ctl1 view.cml sunysb center.cml sunysb center.cml sunysb center.cml synysb confhome.cml synysb confhome.cml The first is a directory, the second is a filename in that directory. I would like have a per-directory count of hits on a particular file then email the results: echo "Directory $dir had $count hits on file $filename." >> $file_to_email I understand that first I must read the $dir and $filename into an array, which I may then traverse in order to keep a count of occurrences. How exactly do I read into that array? TIA, Godwin

If you knew anything about perl at all, you'd know that you can do everything you want to do here, without external grepping or awking, or two-dimensional arrays. I would use a hash. The directory is the name of the hash, the file as the key of the hash, and keep count using the value of the hash. However, there are as many ways to do any given thing in perl as there are people using perl.

Superma #3 / 3	Reading into a two-dimensional array from STDIN I appreciate your point in the right direction. If I may extend my welcome to ask for pointers on "hash", I'd be even more appreciative. Trouble is, I don't really know Perl other than to know is a great data extraction tool. tnx, Godwin Quote: > > perform some grep(ing) and awk(ing) to get multiple occurrences of: > > ctl1 view.cml > > sunysb center.cml > > sunysb center.cml > > sunysb center.cml > > synysb confhome.cml > > synysb confhome.cml > > I understand that first I must read the $dir and $filename into an array, > > which I may then traverse in order to keep a count of occurrences.
