Now use the cat command to display the contents of do-bots. If you happened to try to fetch the robots. You can verify this by using the -I flag, which displays the request headers rather than the contents of the file:. The output shows that the URL was redirected. The first line of the output tells you that it was moved, and the Location line tells you where:. You could use curl to make another request manually, or you can use the --location or -L argument which tells curl to redo the request to the new location whenever it encounters a redirect.
Give it a try:. I have tried to do in bash script: iiumlabs. If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;. OK, considering that you are using Windows, the most simple way to do that is to use the standard ftp tool bundled with it.
I base the following solution on Windows XP, hoping it'll work as well or with minor modifications on other versions.
First of all, you need to create a batch script file for the ftp program, containing instructions for it. Name it as you want, and put into it:. The first line opens a connection to the ftp server at ftp. The two following lines specify the login, and the password which ftp will ask for replace login and pass with just the login and password, without any keywords. Finally, you use quit to close the ftp program without interactive prompt. If you needed to enter some directory first, add a cd command before mget.
It should be pretty straightforward. Sadly, file transfer over SSH is not natively supported in Windows. But for that case, you'd probably want to use PuTTy tools anyway. The one of particular interest for this case would be pscp which is practically the PuTTy counter-part of the openssh scp command. If you authenticate using a key file, you should pass it using -i path-to-key-file.
If you use password, -pw pass. Note that the address in the browser address bar is a local file on this computer, not a remote website. We can create a file by using the -o output option, and telling curl to create the file. To have the text-based download information replaced by a simple progress bar, use the - progress bar option. It is easy to restart a download that has been terminated or interrupted. To restart the download, use the -C continue at option. This causes curl to restart the download at a specified point or offset within the target file.
If you use a hyphen - as the offset, curl will look at the already downloaded portion of the file and determine the correct offset to use for itself. Using xargs we can download multiple URLs at once. Perhaps we want to download a series of web pages that make up a single article or tutorial. This is the command we need to use to have xargs pass these URLs to curl one at a time:. The -n 1 option tells xargs to treat each line of the text file as a single parameter.
Checking in the file browser shows the multiple files have been downloaded. Each one bears the name it had on the remote server. Using curl with a File Transfer Protocol FTP server is easy, even if you have to authenticate with a username and password. This is a free-for-testing FTP server hosted by Rebex.
Use the same command as a moment ago, with the filename appended to it:. In almost all cases, it is going to be more convenient to have the retrieved file saved to disk for us, rather than displayed in the terminal window. Once more we can use the -O remote file output command to have the file saved to disk, with the same filename that it has on the remote server.
The file is retrieved and saved to disk. We can use ls to check the file details. It has the same name as the file on the FTP server, and it is the same length, bytes.
Some remote servers will accept parameters in requests that are sent to them. Seems like a nice addon, ArkadiuszDrabczyk. However, I would like to download the files given a list of DOIs from a remote server. Add a comment. I managed to get this fine wget -O main.
