My server is Windows Server. I would like to replicate the Unix tail command in Windows Server.
Unix Server: tail -f test.txt
PowerShell: Get-Content test.txt
How to execute in Windows Server?
Below command is not working:
powershell -File "Get-Content test.txt"
Error message:
Unable to execute program 'powershell -File "\"Get-Content...
Any idea?
Get-Content is not a file; it is a cmdlet. The -file parameter to Powershell.exe instructs Powershell to read the file supplied and execute the commands in it, as a script.
You can pass commands directly to Powershell by using the -command parameter; the parameter can be a quoted string, which is interpreted as a Powershell command. You would therefore want to use
powershell -command "Get-Content test.txt"
in the simplest case.
Note that Powershell.exe must be in your system path; if it is not, you would need to supply the full path to powershell, e.g.,
C:\WINDOWS\System32\WindowsPowerShell\v1.0\powershell.exe -command "Get-Content text.txt"
This question is very similar - perhaps essentially identical - to Unix tail equivalent command in Windows Powershell; I would recommend reading that question and its answers as well.
Additionally, exploring the help for Get-Content will provide useful information.
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command Get-Content test.txtWorking fine after setting full path of powershell.exe and without any quotes
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command Get-Content test.txt
Within a powershell window :
Get-Content test.txt
command returns :
hello world. i'm inside test.txt. bye.
powershell -File "myScript.ps1"vspowershell -Command "Get-Content test.txt"-Tailfor following the file), but his error message suggests that for some reason his entire statement is interpreted as a single command.
