Redirecting standard input\output in Windows PowerShell
You can't hook a file directly to stdin, but you can still access stdin.
Get-Content input.txt | ./program > output.txt
If there is someone looking for 'Get-Content' alternative for large files (as me) you can use CMD in PowerShell:
cmd.exe /c ".\program < .\input.txt"
Or you can use this PowerShell command:
Start-Process .\program.exe -RedirectStandardInput .\input.txt -NoNewWindow -Wait
It will run the program synchronously in same window. But I was not able to find out how to write result from this command to a variable when I run it in PowerShell script because it always writes data to the console.
EDIT:
To get output from Start-Process you can use option
-RedirectStandardOutput
for redirecting output to file and then read it from file:
Start-Process ".\program.exe" -RedirectStandardInput ".\input.txt" -RedirectStandardOutput ".\temp.txt" -NoNewWindow -Wait$Result = Get-Content ".\temp.txt"
For output redirection you can use:
command > filename Redirect command output to a file (overwrite) command >> filename APPEND into a file command 2> filename Redirect Errors
Input redirection works in a different way. For example see this Cmdlet http://technet.microsoft.com/en-us/library/ee176843.aspx
