Powershell script to download file from ftp
If you are working in a hybrid IT environment, you often need to download or upload files from or to the cloud in your PowerShell scripts. If you only use Windows servers that communicate through the Server Message Block SMB protocol, you can simply use the Copy-Item cmdlet to copy the file from a network share:. This assumes that you have powershell script to download file from ftp VPN solution in place so that your cloud network virtually belongs to your intranet.
Things get a bit more complicated if we are leaving the intranet and have to download from an extranet or the Internet. The next simple case is where you have to download a file from the web or from an FTP server. In PowerShell 2, you had to use the New-Object cmdlet for this purpose:. This is perhaps an understatement; Invoke-WebRequest is more powerful than wget because it allows you to not only download files but also parse them. But this is a topic for powershell script to download file from ftp post.
In the example, we just download the HTML page that the web server at www. Note that, if you only specify the folder without the file name, as you can do with Copy-ItemPowerShell will error:.
If you omit the local path to the folder, Invoke-WebRequest will just use your current folder. The -Outfile parameter is always required if you want to save the file. The reason is that, by default, Invoke-WebRequest sends the downloaded file to the pipeline. However, the pipeline will then not just contain the contents of the file. Instead, you powershell script to download file from ftp find an object with a variety of properties and methods that allow you to analyze text files.
To only read the contents of the text file, we need to read the Content property of the object in the pipeline:. This command does the same thing as the previous one, powershell script to download file from ftp. If you want to have the file in the pipeline and store it locally, you have to use -PassThru parameter:.
Note that, if you omit the -Credential parameter, PowerShell will not prompt you for a user name and password and will throw this error:. You have to at least pass the user name with the -Credential parameter.
PowerShell will then ask for the password. If you want to avoid a dialog window in your script, you can store the credentials in a PSCredential object:.
You can use the -UseDefaultCredentials parameter instead of the -Credential parameter if you want to use the credentials of the current user. To add a little extra security, you might want to encrypt the password. If the web server uses basic authentication, your password will be transmitted in clear text if you download via HTTP. Note that this method only works if the web server manages authentication. Nowadays, most websites powershell script to download file from ftp the features of a content management system CMS to authenticate users.
Usually, you then have to fill out an HTML form. I will explain in one of my next posts how you can do this with Invoke-WebRequest. However, third-party PowerShell modules exist that step into the breach. Join the 4sysops PowerShell group! Your question was not answered?
Ask in the forum! I am running a script on a scheduled basis daily to download a. However the uri changes every month, so I was wondering if the uri destination value can be set based on a value in a reference file as opposed to hard coding it, if so how? Is the date on the website? Will take some coding. Great tips, can you tell me how you would apply this same concept in powershell to download all files from a web folder?
Thank you in advance. Im not sure whether this is possible. You would somehow need to enumerate the content of the folder and then download it. That is normally forbidden by webservers. Then you could parse the output and ask for specific files to be downloaded or all of them.
But I dont see any straight-forward way. Your email address will not be published. Notify me of followup comments via e-mail. Receive new post notifications. Member Leaderboard — Month.
