Well - you can override the exit builtin (in bash) with a function
Obviously this is a bit of a kludge.
I'd say it'd be easiest to write your own exit function and then call that function instead of exit when you leave the program, e.g.
Yet another way to do it (and how I'd personally go about it) would be to call your script from within another script. You could then test the value of $? and process accordingly... e.g.

i downloaded a text file from metalab.unc.edu called sh.txt and in this reference manual it refers to shell scripting exit status .. at the end of one of the examples that author gave an exit status of 127..
to what does a 127 exit status refer too and what is its purpose in the code.

I'm preparing for exam and one of exams is to write own test command...
I wonder if in unix is a command which just returns exit code you specify..
I know I can easily write a function like this:
exStatus() {
return $1
}
-> my question is rather theoretical
thank you! (9 Replies)
hi,
exit status variable $?, returns some digits.
0 ---> succes.
1..126
Failure (the program itself will decide what the numbers mean)

Command not found

The program did not exit normally. (E.g., it crashed, or received a signal)
255
Invalid exit code

exit
EXIT(3) 1 EXIT(3)exit - Output a message and terminate the current scriptSYNOPSIS
void exit ([string $status])
DESCRIPTION
void exit (int $status)
Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.
exit is a language construct and it can be called without parentheses if no $status is passed.
PARAMETERS
o $status
- If $status is a string, this function prints the $status just before exiting. If $status is an integer, that value will be used
as the exit status and not printed. Exit statuses should be in the range 0 to 254, the exit status 255 is reserved by PHP and
shall not be used. The status 0 is used to terminate the program successfully.
Note
PHP >= 4.2.0 does NOT print the $status if it is an integer.
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
exit example
<?php
$filename = '/path/to/data-file';
$file = fopen($filename, 'r')
or exit("unable to open file ($filename)");
?>
Example #2
exit status example
<?php
//exit program normally
exit;
exit();
exit(0);
//exit with an error code
exit(1);
exit(0376); //octal
?>
Example #3
Shutdown functions and destructors run regardless
<?php
class Foo
{
public function __destruct()
{
echo 'Destruct: ' . __METHOD__ . '()' . PHP_EOL;
}
}
function shutdown()
{
echo 'Shutdown: ' . __FUNCTION__ . '()' . PHP_EOL;
}
$foo = new Foo();
register_shutdown_function('shutdown');
exit();
echo 'This will not be output.';
?>
The above example will output:
Shutdown: shutdown()
Destruct: Foo::__destruct()
NOTES
Note
Because this is a language construct and not a function, it cannot be called using variable functions.
Note
This language construct is equivalent to die(3).
