Very Computer

From the UNIX command line I would like to prompt the user for a
password using getpass (to hide the password) and then pipe the
password to a korn shell script.

Here is what I have tried so far:

#include <stdlib.h>
/* hide_password.c */

int main(argc, argv)
int argc;
char *argv[];
{
 char *pw;
 char cmdline[128];
 pw = getpass("Password: ");
 sprintf(cmdline,"use_password.ksh %s",pw);
 system(cmdline);

Quote:}

---------------------------------
#!/bin/ksh
# use_password.ksh
print $1
---------------------------------
$ hide_password | use_password.ksh
Password:

Broken Pipe
$
---------------------------------

Can anyone help me with this?

Thanks

I don't see what you're trying to pipe (you never write anything to
stdout, and your script never reads anything). In fact, you're _already_
doing everything you want (i.e. building the command, including the
password obtained, and running the script via system()) in the code
you've posted.

use_password.ksh `hide_password`

Your script does not read from stdin; it uses a command line argument.

or do this to read from stdin:

#!/bin/ksh
# use_password.ksh
read p
echo $p

$ hide_password | use_password.ksh
