    That's a nice & quick tutorial.
    Back in 2009 and 2011 the CRU email leak took place. I used Kate and the following grep command to search all 1,072 emails for words and phrases:
    grep -B3 -A4 kill /home/jerry/Documents/IPCC stuff/FOIA_2009/FOIA/mail/*
    The "-B3" and "-A4" would print 3 lines before and 4 lines after the line that contained the match.

    I ran this using Kate. I had all 1,072 files listed in the left "Documents" panel, and had the Kate terminal panel open. I ran the grep command in the terminal panel. A listing of all the matches appeared in the terminal panel. If I clicked on the file name in the terminal panel that file was loaded into the text panel with the matched line in the center. From there I could copy&paste lines from the emails into a document I was writing about a selected topic. Kate and grep are powerful combinations.
