This is a Bash-question, not cygwin - i.e. off topic here ;-)


$ cat t.c 
#include <stdio.h>

int main(int argc, char **argv) {

  if (argc<=1)
    printf("Use: %s [o] [e]\n" \
           " o - print short text on stdout\n" \
           " e - print short text on stderr\n",argv[0]);
  else {

    if ((argc>1) && (argv[1][0]=='o'))
      fprintf(stdout,"%s: This text on stdout\n",argv[0]);
        
    if ((argc>2) && (argv[2][0]=='e'))
      fprintf(stderr,"%s: This text on stderr\n",argv[0]);
      
    }
    
return 0;
}
$ gcc t.c

$ a o e 2>&1 | less
