DESCRIPTION
httrack allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads.

EXAMPLES

httrack www.example.com/bob/
    mirror site www.example.com/bob/ and only this site

httrack www.example.com/bob/ www.anothertest.com/mike/ +*.com/*.jpg -mime:application/*
    mirror the two sites together (with shared links) and accept any .jpg files on .com sites

httrack www.example.com/bob/bobby.html +* -r6

httrack www.example.com/bob/bobby.html --spider -P proxy.myhost.com:8080

httrack --update

httrack

httrack --continue

OPTIONS

  General options:

-O  path for mirror/logfiles+cache (-O path_mirror[,path_cache_and_logfiles]) (--path <param>)

  Action options:

-w  *mirror web sites (--mirror)

-W  mirror web sites, semi-automatic (asks questions) (--mirror-wizard)

-g  just get files (saved in the current directory) (--get-files)

-i  continue an interrupted mirror using the cache (--continue)

-Y  mirror ALL links located in the first level pages (mirror links) (--mirrorlinks)

  Proxy options:

-P  proxy use (-P [socks5://|connect://][user:pass@]proxy:port) (--proxy <param>)

-%f *use proxy for ftp (f0 don't use) (--httpproxy-ftp[=N])

-%b use this local hostname to make/send requests (-%b hostname) (--bind <param>)

  Limits options:

-rN set the mirror depth to N (* r9999) (--depth[=N])

-%eN
    set the external links depth to N (* %e0) (--ext-depth[=N])

-mN maximum file length for a non-html file (--max-files[=N])

-mN,N2
    maximum file length for non html (N) and html (N2)

-MN maximum overall size that can be uploaded/scanned (--max-size[=N])

-EN maximum mirror time in seconds (60=1 minute, 3600=1 hour) (--max-time[=N])

-AN maximum transfer rate in bytes/seconds (1000=1KB/s max) (--max-rate[=N])

-%cN
    maximum number of connections/seconds (*%c5) (--connection-per-second[=N])

-%G random pause of MIN[:MAX] seconds between files (e.g. %G5:10) (--pause <param>)

-GN pause transfer if N bytes reached, and wait until lock file is deleted (--max-pause[=N])

  Flow control:

-cN number of multiple connections (*c4) (--sockets[=N])

-TN timeout, number of seconds after a non-responding link is shutdown; also bounds host name resolution (--timeout[=N])

-RN number of retries, in case of timeout or non-fatal errors (*R1) (--retries[=N])

-JN traffic jam control, minimum transfert rate (bytes/seconds) tolerated for a link (--min-rate[=N])

-HN host is abandoned if: 0=never, 1=timeout, 2=slow, 3=timeout or slow (--host-control[=N])

  Links options:

-%P *extended parsing, attempt to parse all links, even in unknown tags or Javascript (%P0 don't use) (--extended-parsing[=N])

-n  get non-html files 'near' an html file (ex: an image located outside) (--near)

-t  test all URLs (even forbidden ones) (--test)

-%L <file> add all URL located in this text file (one URL per line) (--list <param>)

-%S <file> add all scan rules located in this text file (one scan rule per line) (--urllist <param>)

-%m seed the crawl from the site's sitemap (robots.txt Sitemap:, then /sitemap.xml); --sitemap-url URL names one explicitly. A sitemap you name, or one the site declares, is fetched even under robots.txt Disallow; only the guessed /sitemap.xml obeys it. The URLs found still pass every filter and scope rule (--sitemap)

  Build options:

-NN structure type (0 *original structure, 1+: see below) (--structure[=N])
    or user defined structure (-N "%h%p/%n%q.%t")

-%N delayed type check, don't make any link test but wait for files download to start instead (experimental) (%N0 don't use, %N1 use for unknown extensions, * %N2 always use) (--delayed-type-check)

-%D cached delayed type check, don't wait for remote type during updates, to speedup them (%D0 wait, * %D1 don't wait) (--cached-delayed-type-check)

-%M generate a RFC MIME-encapsulated full-archive (.mht) (--mime-html)

-%Z after the mirror, rewrite each saved page with its stylesheets, scripts, images and fonts inlined as data: URIs, so any page opens by double-click anywhere (links between pages stay relative; audio and video stay links); --single-file-max-size N caps each asset (default 10485760 bytes). %M is the better container where a Chromium-family browser is a given: one archive, no base64 tax on text, a shared asset stored once (--single-file)

-%t keep the original file extension, don't rewrite it from the MIME type (%t0 rewrite)

-LN long names (L1 *long names / L0 8-3 conversion / L2 ISO9660 compatible) (--long-names[=N])

-KN keep original links (e.g. http://www.adr/link) (K0 *relative link, K absolute links, K4 original links, K3 absolute URI links, K5 transparent proxy link) (--keep-links[=N])

-x  replace external html links by error pages (--replace-external)

-%x do not include any password for external password protected websites (%x0 include) (--disable-passwords)

-%q *include query string for local files (useless, for information purpose only) (%q0 don't include) (--include-query-string)

-%g strip query keys for dedup ([host/pattern=]key1,key2,...) (--strip-query <param>)

-o  *save the server's error pages (404..) (o0 discard them) (--generate-errors)

-X  *purge old files after update (X0 keep delete) (--purge-old[=N])

-%p preserve html files 'as is' (identical to '-K4 -%F ""') (--preserve)

-%T links conversion to UTF-8 (--utf8-conversion)

  Spider options:

-bN accept cookies in cookies.txt (0=do not accept,* 1=accept) (--cookies[=N])

-%K load extra cookies from a Netscape cookies.txt (--cookies-file <param>)

-%Y explain which filter rule accepts or rejects a URL, then exit (--why <param>)

-u  check document type if unknown (cgi,asp..) (u0 don't check, * u1 check but /, u2 check always) (--check-type[=N])

-j  *parse scripts (j0 don't parse, bitmask: |1 parse default, |4 don't parse .js |8 don't be aggressive) (--parse-java[=N])

-sN follow robots.txt and meta robots tags (0=never,1=sometimes,* 2=always, 3=always (even strict rules)) (--robots[=N])

-%h force HTTP/1.0 requests (reduce update features, only for old servers or proxies) (--http-10)

-%k use keep-alive if possible, greately reducing latency for small files and test requests (%k0 don't use) (--keep-alive)

-%z do not request compressed content (%z0 request) (--disable-compression)

-%B tolerant requests (accept bogus responses on some servers, but not standard!) (--tolerant)

-%s update hacks: various hacks to limit re-transfers when updating (identical size, bogus response..) (--updatehack)

-%u url hacks: various hacks to limit duplicate URLs (strip //, www.foo.com==foo.com..) (--urlhack)
    opt out of one url-hack part: --keep-www-prefix (www.foo.com<>foo.com), --keep-double-slashes (//), --keep-query-order (?b&a)

-%A assume that a type (cgi,asp..) is always linked with a mime type (-%A php3,cgi=text/html;dat,bin=application/x-zip) (--assume <param>)
    shortcut: '--assume standard' is equivalent to -%A php2 php3 php4 php cgi asp jsp pl cfm nsf=text/html
    can also be used to force a specific file type: --assume foo.cgi=text/html

-@iN
    internet protocol (0=both ipv6+ipv4, 4=ipv4 only, 6=ipv6 only) (--protocol[=N])

FILES
/etc/httrack.conf
    The system wide configuration file.

ENVIRONMENT

HOME
    Is being used if you defined in /etc/httrack.conf the line path ~/websites/#

DIAGNOSTICS
Errors/Warnings are reported to hts-log.txt by default, or to stderr if the -v option was specified.

LIMITS
These are the principals limits of HTTrack for that moment. Note that we did not heard about any other utility that would have solved them. - Several scripts generating complex filenames may not find them (ex: img.src='image'+a+Mobj.dst+'.gif') - Cgi-bin links may not work properly in some cases (parameters needed). To avoid them: use filters like -*cgi-bin*

BUGS
Please reports bugs to <bugs@httrack.com>. Include a complete, self-contained example that will allow the bug to be reproduced, and say which version of httrack you are using. Do not forget to detail options used, OS version, and any other information you deem necessary.
