Issuing a Here Document as a Single Line Command
How can I run a here document on just one line? I ask, because I need to issue it from C++ as a system() or similar command and for security reasons I don't want to write out a shell script file from the program and run it.
For example, how could I write:
passwd test <<EOF
n3wp3ss
n3wp3ss
EOF
as s single command? I've tried semicolons and they don't work for this.
Thanks in advance.

run
run(1F) FMLI Commands run(1F)
NAME
run - run an executable
SYNOPSIS
run [-s] [-e] [-n] [-t string] program
DESCRIPTION
The run command runs program, using the PATH variable to find it. By default, when program has completed, the user is prompted (Press ENTER
to continue:), before being returned to FMLI. The argument program is a system executable followed by its options (if any).
OPTIONS
The following options are supported:
-e If -e is specified, the user is prompted before returning to FMLI only if there is an error condition
-n If -n is specified, the user is never prompted before returning to FMLI (useful for programs like vi, in which the user must do
some specific action to exit in the first place).
-s The -s option means "silent", implying that the screen does not have to be repainted when program has completed. The -s option
should only be used when program does not write to the terminal. In addition, when -s is used, program cannot be interrupted,
even if it recognizes interrupts.
-tstring If -t is specified, string is the name this process has in the pop-up menu generated by the frm-list command.
EXAMPLES
Example 1 Sample Output of the run Command
Here is a menu that uses run:
menu="Edit special System files"
name="Password file"
action=`run -e vi /etc/passwd`
name="Group file"
action=`run -e vi /etc/group`
name="My .profile"
action=`run -n vi $HOME/.profile`
