hxcopy (1)

hxcopy [\| -i old-URL \|] [\| -o new-URL \|] [\| -s \|] [\| -v \|] [\| file-or-URL [\| file-or-URL \|] \|]

The hxcopy command copies its first argument to its second argument, while updating relative links. The input is assumed to be HTML or XHTML and may be slightly reformatted in the process.

If the second argument is omitted, hxcopy writes to standard output. In this case the option -o is required. If the first argument is also omitted, hxcopy reads from standard input. In this case the option -i is required.

The following options are supported:

-i old-URL

For the purposes of updating relative links, act as if old-URL is the location from which the input is copied. If this option is omitted, the actual location of the first argument is used for calculating relative links.

-o new-URL

For the purposed of updating relative links, act as if new-URL is the location to which the input is copied. If this option is omitted, the actual location of the second argument is used for calculating relative links.

-s

Also replace links to self. This effects the treatment of empty URLs, i.e., links to the document itself that do not explicitly name the document. Without -s, implicit links to the document itself (href=""), to a fragment of the document itself (href="#foo") or to a query over the document itself (href="?query") are not changed and will thus refer to (a fragment of) the new document. With -s, these links are rewritten to refer to (a fragment of) the old document instead.

-v

Print the version number and exit immediately.

To use a proxy to retrieve remote files, set the environment variables http_proxy and ftp_proxy. E.g., http_proxy="http://localhost:8080/"

Unlike the last argument of cp(1), the last argument of hxcopy must be a file, not a directory.

The second argument must be a local file. Writing to a URL is not yet implemented. To work around this, replace hxcopy file.html http://example.org/file.html by hxcopy -o http://example.org/file.html file.html tmp.html and then upload tmp.html to the given URL with some other command, such as curl(1). The first argument, however, may be a URL. hxcopy will download the given file. (Currently only HTTP is supported.)

Assume the HTML file foo.html contains a relative link to "../bar.html". Here are some examples of commands:

hxcopy foo.html bar/foo.html

The file foo.html is copied to ../bar/foo.html and the relative link to "../bar.html" becomes "../../bar.html".

hxcopy foo.html ../foo.html

The file foo.html is copied to ../foo.html and the relative link to "../bar.html" is rewritten as "bar.html".

hxcopy -i http://my.org/dir1/foo.html -o http://my.org/foo.html file1.html file2.html

The file file1.html is copied to file2.html and the relative link to "../bar.html" is rewritten as "bar.html". A command like this may be useful to update files that are later uploaded to a server.
