A kill file (also killfile, bozo bin or twit list) is a per-user file used by some Usenet reading programs (originally Larry Wall's rn) to discard summarily (without presenting for reading) articles matching some unwanted patterns of subject, author, or other header lines.
Thus to add a person (or subject) to one's kill file is to arrange for that person to be ignored by one's newsreader in the future. By extension, it may be used for a decision to ignore the person or subject in other media. Sometimes more than one kill file will be used. Some newsreader programs also allow the user to specify a time period to keep an author in the kill file.
Newer newsreader software like Gnus often provides a more advanced form of filter known as a score file, which can use multiple rules to determine which articles are shown. Web-based forums usually have a similar feature called ignore list, which hides any posts sent by users on the list.
Famous quotes containing the words kill and/or file:
“Look, Tiger, if I was to be buried in potter’s field, it’d just about kill me!”
—Samuel Fuller (b. 1911)
“While waiting to get married, several forms of employment were acceptable. Teaching kindergarten was for those girls who stayed in school four years. The rest were secretaries, typists, file clerks, or receptionists in insurance firms or banks, preferably those owned or run by the family, but respectable enough if the boss was an upstanding Christian member of the community.”
—Barbara Howar (b. 1934)
