It also provides users with a variety of features ranging from recursive downloading to playing and pausing the downloads as well as limiting its bandwidth. Moreover, it is cross-platform which gives it quite the edge over many other command line downloaders as well as graphical downloaders.
Wget usually comes pre-installed with most of the Linux Distributions. It is to be noted that the command given above is for only Debian based Linux systems such as Ubuntu. If a user has a Red Hat Linux system such as Fedora, then the user needs to enter the following command into the command line:. As mentioned before, Wget has multiple features incorporated inside of it.
The most basic operation that Wget offers to users is downloading files by simply using its URL. This can be done by inputting the following command into the terminal:.
Let us show an example to further clarify this. We will be downloading a simple image in the png format from the internet. I am using Ubuntu here but apart from the installation, rest of the commands are equally valid for all other Linux distributions. You can download a single file, multiple files, entire directory or even an entire website using wget. This means you can easily use it in scripts or even build tools like uGet download manager.
Most Linux distributions come with wget preinstalled. On Ubuntu and Debian based distribution, you can use the apt package manager command:. You just need to provide the URL of the file or webpage.
It will download the file with its original name in the directory you are in. It will be a good idea to provide custom name to downloaded file.
Suppose you are browsing an FTP server and you need to download an entire directory, you can use the recursive option. Specify a list of files to download using the -i switch. Start by creating a regular text file with a list of downloads, one full URL per line. Use wget to download all the files using the following command:. The trouble with downloading files from the internet is that sometimes the file or URL is unavailable. The timeout for the connection can take a while, and if you are trying to download lots of files, it is counterproductive to wait for the default timeout.
Specify your own timeout the amount of time the system waits for a file to begin, in seconds using the following syntax:. The above command stops the download of files wgen megabytes has been reached. You can also specify the quota in bytes use b instead of m or kilobytes use k instead of m.
You may not have a download limit but you might have a slow internet connection. To download files without devouring all the available bandwidth on your connection, specify a limit that sets a maximum download rate.
The above command limits the download rate to 20 kilobytes per second. Please help me with some command that can help to do download the file from server to local machine. Thanks in advance. You should use rsync or scp command to get the file from remote server to local, please go through these articles on how to do it.. Have a question or suggestion?

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. The parameters might be used to format the returned data, for example, or they may be used to select the exact data that the user wishes to retrieve.
It is often possible to interact with web application programming interfaces APIs using curl. As a simple example, the ipify website has an API can be queried to ascertain your external IP address. It returns a JSON object describing a book. You can find these on the back cover of most books, usually below a barcode. Especially if the protocol was one of the many not supported by wget.
