Replacement for $() in Windows batch script
up vote

I am trying to convert my bash script into a Windows batch file. It's a really simple one liner that's supposed to feed the contents of a file as arguments to script.exe, and send the results to output.txt.
This is the working bash script:
./script.exe $(cat input.txt) > output.txt
I know this might be bad style, but it works. The problem is, I have no idea how to do something like $() in a windows batch file. When I use it it sends the string "$(cat input.txt)" as the argument instead of running the command.

If the unknown windows script.exe accepts redirected input, eithertype input.txt|script.exe >output.txtorscript.exe <input.txt >output.txtotherwise you can have bash through wsl or a similar syntax with powershell.

This bash construct is called command substitution. Here is a great answer from @MichaelBurr.
You can get a similar functionality using cmd.exe scripts with the
for /fcommand:
for /f "usebackq tokens=*" %%a in (`echo Test`) do my_command %%a
Yeah, it's kinda non-obvious (to say the least), but it's what's
there.
See
for /?for the gory details.
Sidenote: I thought that to use "
echo" inside the backticks in a
"for /f" command would need to be done using "cmd.exe /c echo" since
Testechois an internal command tocmd.exe, but it works
in the more natural way. Windows batch scripts always surprise me
somehow (but not usually in a good way).
