wget to console
Use the -O - option to output contents to the console.
$ wget -O - http://google.ca
Since the contents go to stdout, you can pipe it to a shell to execute remote commands:
$ wget -O - http://scripthost.local/fix_graphics.sh | sh
Note: This is equivalent to using curl with no options. Eg: curl http://google.ca.
Save to Directory
Use the -P to specify the prefix of the output file.
$ wget -P /tmp http://google.ca/
Saving an Entire Open Directory
To download an entire open directory from a remote server:
$ wget --no-check-certificate -np -r -c --reject "index.html*" -e robots=off http://server/remote/dir
Where:
| Flag | Description |
|---|---|
--no-check-certificate
|
Don't check SSL certificates |
-np
|
No parent directory (don't crawl up) |
-r
|
Recursive |
-c
|
Continue |
--reject "index.html*"
|
Don't save index.html* files from directory listing |
-e robots=off
|
Don't check robots.txt |
wget on FreeBSD
wget is available in ports under ftp/wget. If you don't want to compile it, you could just use fetch (1) to download files.
