in reply to Re^3: Subsetting text files containing e-mails
in thread Subsetting text files containing e-mails

Aha! I get it. So essentially when a paragraph is found that contains '^From:' it places a marker at the beginning of that paragraph?

I could not figure out how it was handling all the blank lines within the e-mails until I realized that it wasn't and didn't need to.

Just to be clear, in order to actually subset the file I would still need to close and reopen it, right? I'm thinking something like:

open (<MYDATA>, $filein); while (<MYDATA>) { if (/^---- Email 1/ ... /---- Email2/) { open (<MYOUTPUT>, ">$fileout"); print MYOUTPUT $_; close (MYOUTPUT); } } close (MYDATA);

I suppose I might create a loop so that a new value for the search terms (i.e., /^---- Email 2/ ... /^---- Email 3/ for the second iteration, etc.) is selected as well as a new output file to catch the results...
