About this capture

COLLECTED BY

Organization:Internet Archive

These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.

Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.

The goal is tofix all broken links on the web. Crawls of supported "No More 404" sites.

Collection:Wikipedia Near Real Time (from IRC)

This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.

This is part of the Internet Archive's attempt torid the web of broken links.

NAME

file —determine file type

SYNOPSIS

file

[-bchiLsW]file ...

DESCRIPTION

Thefile utility tests each argument and attempts to determine its type. Three sets of tests are performed:

Filesystem tests, for example if a file is empty, or a special file such as a socket or named pipe (FIFO).
“Magic” tests for data in particular fixed formats. These are loaded from the/etc/magic file (or~/.magic instead if it exists andfile is not running as root). The file format is described inmagic(5).
Tests for text files such as plain ASCII or C programming language files.

The first test which succeeds causes the file type to be printed. The type will often contain one of the wordstext (contains only printing characters and is probably safe to read on an ASCII terminal),executable (the file contains a compiled executable program) ordata meaning anything else.

Iffile is a single dash (‘-’),file reads from the standard input.

The options are as follows:


-b,--brief: Does not prepend filenames to output lines.

-c: Prints a summary of the parsed magic file; usually used for debugging.

-h: Causes symlinks not to be followed. This is the default.

-i,--mime,--mime-type: Outputs MIME type strings rather than the more traditional human-readable ones. Thus it may say “text/plain” rather than “ASCII text”.

-L,--dereference: Causes symlinks to be followed.

-s: Attempts to read block and character device files, not just regular files.

-W: Displays warnings when parsing the magic file or applying its tests. Usually used for debugging.

FILES

/etc/magic: default magic file

EXIT STATUS

Thefile utility exits 0 on success, and >0 if an error occurs.

AUTHORS

file commands have appeared in many previous versions ofUNIX. This version was written byNicholas Marriott forOpenBSD 5.8 to replace the previous version originally written byIan Darwin.

There is a large number of contributors to the magic files; many are listed in the source files.
