Good afternoon ladies and gents (although I've got a feeling I'm speaking to mostly gents.
I've got a file that I need to read into a hash line by line, the file in the form of:
Data_Type:1234567890 data data data data data
Data_Type:1237834810 data data data data data
after the inital key, there is a tab, followed by multiple descriptions...lengths and number of them vary again separated by tabs. However I only want to split them once into $id and $descriptions.
So far I know I need
open(IN,'file.txt');
while($line = <IN>)
{
chomp $line;
($id, $description)### regex expression to split it
push(%hash{$id, $descriptions)### then a push?
}
I hope you can help guys, I'm new at programming, so far I'm doing ok, but this has stumped me.
Thanks in advance
