MEL used to be the maya embedded scripting language. What does that have to do with a bash terminal command? It sounds like you need the MEL syntax to execute a bash script or command.
I do not know MEL - you get to figure out how to execute something like this native UNIX statement:
where foo is the valid username and bar is the valid password. And be able to see the status return code of the script a 1 (one) or a 0 (zero).
script lives in /somefolder/somewhere/you/put/it, with file permissions 755:
myscript.sh does all the stuff you cannot do in "one line", it has a status code of 0 if all is well, 1 otherwise.
Plus - as a wild guess - I believe that your question is probably ill-formed. There must be a way to run your MEL script process from bash itself under maya, maya is an executable. You are already running MEL.
You could construct your password query there, since you appear to have a hard-coded password and username anyway. Then either run or not run the entire maya/app/scripts bundle.
partial bash/Pseudocode ( I know nothing about maya)
Can we write a script to telnet to a unix server from unix with the username and password hardcoded in the script??
something like ssh a@b -p password ??? (5 Replies)

system
SYSTEM(3) Linux Programmer's Manual SYSTEM(3)NAME
system - execute a shell command
SYNOPSIS
#include <stdlib.h>
int system(const char *string);
DESCRIPTION
system() executes a command specified in string by calling /bin/sh -c string, and returns after the command has been completed. During
execution of the command, SIGCHLD will be blocked, and SIGINT and SIGQUIT will be ignored.
RETURN VALUE
The value returned is -1 on error (e.g. fork failed), and the return status of the command otherwise. This latter return status is in the
format specified in wait(2). Thus, the exit code of the command will be WEXITSTATUS(status). In case /bin/sh could not be executed, the
exit status will be that of a command that does exit(127).
If the value of string is NULL, system() returns nonzero if the shell is available, and zero if not.
system() does not affect the wait status of any other children.
CONFORMING TO
ANSI C, POSIX.2, BSD 4.3
NOTES
As mentioned, system() ignores SIGINT and SIGQUIT. This may make programs that call it from a loop uninterruptable, unless they take care
themselves to check the exit status of the child. E.g.
while(something) {
int ret = system("foo");
if (WIFSIGNALED(ret) &&
(WTERMSIG(ret) == SIGINT || WTERMSIG(ret) == SIGQUIT))
break;
}
Do not use system() from a program with suid or sgid privileges, because strange values for some environment variables might be used to
subvert system integrity. Use the exec(3) family of functions instead, but not execlp(3) or execvp(3). system() will not, in fact, work
properly from programs with suid or sgid privileges on systems on which /bin/sh is bash version 2, since bash 2 drops privileges on
startup. (Debian uses a modified bash which does not do this when invoked as sh.)
The check for the availability of /bin/sh is not actually performed; it is always assumed to be available. ISO C specifies the check, but
POSIX.2 specifies that the return shall always be non-zero, since a system without the shell is not conforming, and it is this that is
implemented.
It is possible for the shell command to return 127, so that code is not a sure indication that the execve() call failed.
