Let us show an example to further clarify this. We will be downloading a simple image in the png format from the internet. See the image below for better understanding:. Wget also allows users to download multiple files from different URLs.
This can easily be done by the following command:. Once again, we can show this using an example. We will be downloading two HTML files from two different websites. For better understanding, please look at the image below:. Here filename refers to the name that you want to address the file as.
Using this, we can also change the type of the file. This is shown in the image below:. Wget also allows users to recursively download their files which is basically downloading all the files from the website under a single directory. For more information regarding Wget, users can input the following command into the terminal to get access to all the Wget commands that appear to be available:.
Run just like that it updates inline on the console but when I pipe it, it appends a new line to the file. OK I understand using this will overwrite the file. But only after I run it the first time. I really do not need to keep a log of all the transfer rates and only interested in writing that one line on every update while the application is running. Instead of appending lines during executions, I want it to create a new file or overwrite it every second. For obtaining just the last line while ifstat is executing you could extract it in a 2nd file like this:.
You can try one of the following I do not have your version of ifstat , so I cannot verify this on my own system. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

To download multiple files with PowerShell we first need to know which files are available. We can use the Invoke-WebRequest cmdlet first to get the content from the webpage.
This will return not only the content of the webpage but also other properties, like Links and InputFields. We can filter the links with a simple like query and select only the href property from each link. So we now have the links for all random binary files. All we need to do is download each one of them. It allows you to download multiple files simultaneously in the background with the parameter -Asynchronous.
Other advantages of the BitsTransfer cmdlet is it can handle connection interruptions and is aware of your network bandwidth usage. We can start all the download jobs by using the parameter — Asynchronous. Without it, the BitsTransfer cmdlet downloads the first file completely before starting the next download while putting your script on hold in the meantime.
You can use the Get-BitTransfer cmdlet to show the progress of the download. If you want to stop the download job then use the Remove-BitTransfer cmdlet.
You can stop a single job based on its JobId or all jobs with:. When using Asynchronous it creates a temp file during the download process. But to actually use the file you will need to run the following cmdlet:. Instead, we can simply use the Copy-Item cmd to download a file from a server. On failure move the files back and raise an error. There isn't a simple way to do what you want using just wget unless you know specifically the name of all files, in which case the -O option will allow you to force the filename of the file downloaded.
