How to use pipe for stderr?
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 ((argc1) (argv[1][0]=='o'))
fprintf(stdout,%s: This text on stdout\n,argv[0]);
if ((argc2) (argv[2][0]=='e'))
fprintf(stderr,%s: This text on stderr\n,argv[0]);
}
return 0;
}
$ gcc t.c
$ ls -l a.exe
-rwxr-xr-x1 Hannu 19876 Jun 14 13:02 a.exe*
$ a o e 21 | less
-- less display --
a: This text on stdout
a: This text on stderr
