How do I use a pipe to redirect the output of one command to the input of another

Question

I have a program which sends text to an LED sign   prismcom exe  To use the program to send  Hello    prismcom exe usb Hello   Now  I wish to  for example use a command program called Temperature   temperature   Let s say the program gives your computer s temperature   Your computer is 100 degrees Fahrenheit    Now  I wish to write the output of temperature to prismcom exe   temperature   prismcom exe usb   This does not seem to work   Yes  I ve looked for a solution to this for more than twenty minutes  In all cases  they are either kludges hacks or a solution for something besides the Windows command line   I would appreciate direction as to how I would pipe the output from temperature to prismcom   Thanks   Edit  Prismcom has two arguments  The first will always be  usb   Anything that comes after that will be displayed on the sign

This should work   for  F  tokens     i in   temperature   do prismcom exe usb  i   If running in a batch file  you need to use   i instead of just  i  in both places

Not sure if you are coding these programs  but this is a simple example of how you d do it   program1 c   include  lt stdio h gt  int main  int argc  char   argv           printf   s   argv 1         return 0      rgx cpp   include  lt cstdio gt   include  lt regex gt   include  lt iostream gt  using namespace std  int main  int argc  char   argv           char input 200       fgets input 200 stdin       string s input      smatch m      string reg exp argv 1        regex e reg exp       while  regex search  s m e           for  auto x m  cout  lt  lt  x  lt  lt             cout  lt  lt  endl        s   m suffix   str              return 0      Compile both then run program1 exe  this subject has a submarine as a subsequence    rgx exe   b sub           The   operator simply redirects the output of program1 s printf operation from the stdout stream to the stdin stream whereby it s sitting there waiting for rgx exe to pick up

Try this  Copy this into a batch file - such as send bat - and then simply run send bat to send the message from the temperature program to the prismcom program   temperature exe  gt  msg txt set  p msg   lt  msg txt prismcom exe usb   msg
