NAME

hget  − retrieve a web page corresponding to a url

SYNOPSIS

­hget [ ­-dhv ][ ­-o ­ofile ][ ­-p ­body ][ ­-x ­netmntpt ] ­url

DESCRIPTION

­Hget retrieves the web page specified by the URL ­url and writes it, absent the ­-o option, to standard output.  The known URL types are: http and ftp. 

If ­url is of type HTTP and the ­-p option is specified, then an HTTP POST is performed with ­body as the data to be posted. 

The ­-o option is used to keep a local file in sync with a web page.  If the web page has been modified later than the file, it is copied into the file.  If the file is up to date but incomplete, ­hget will fetch the missing bytes. 

Option ­-h causes HTTP headers to be printed to standard output in addition to the transferred web page. 

Option ­-d turns on debugging written to standard error. 

Normally, ­hget uses the IP stack mounted under /net.  The ­-x option can be used to specify the mount point of a different IP stack to use. 

Option ­-v writes progress lines to standard output once a second.  Each line contains two numbers, the bytes transferred so far and the total length to be transferred. 

If the environment variable ­httpproxy is set, it is used as a URL denoting an HTTP proxy server.  All HTTP accesses use this server to get the page instead of calling the destination server.
