powershell command line parameter are executed in uppercase?

Question

I would like to use a WGET command line program under Windows in a powershell script.

example : wget https://domain-name/file_01.pdf -o wgetlog.txt

Step 1 - Executed with cmd.exe, this command works fine :

• Download the file "file_01.pdf" in the current directory.
• Create a log file named wgetlog.txt in the current directory.

Step 2 - Executed within a powershell script, this command doesn't work as expected :

• Download the file "file_01.pdf" in the current directory
• Rename it as wgetlog.txt.

WGET is a program with case sensitive parameters :

• -o means "create a log file with a specified name"
• -O means "save the downloaded file with a specified name"

So, I suspect that the script executed with powershell don't take in charge the "case sensitive" functionality and execute the command line "after an upper case conversion".

Is there a way to apply the command with case sensitive or a workaround to solve this problem ?

Answer 1

For some inexplicable reason, the Windows PowerShell team decided to make wget the alias name of the Invoke-WebRequest cmdlet.

Invoke-WebRequest does not even try to be compatible with wget.

To make sure PowerShell uses the actual wget program, use its full name, wget.exe

wget.exe https://domain-name/file_01.pdf -o wgetlog.txt
