NAME
       exit,  return,  goto - shell built-in functions to enable the execution
       of the shell to advance beyond its sequence of steps

SYNOPSIS
   sh
       exit [n]


       return [n]

   csh
       exit [( expr )]


       goto label

   ksh88
       *exit [n]


       *return [n]

   ksh
       +exit [n]


       +return [n]

DESCRIPTION
   sh
       exit causes the calling shell or shell script to  exit  with  the  exit
       status  specified  by n. If n is omitted the exit status is that of the
       last command executed (an EOF also causes the shell to exit.)


       return causes a function to exit with the return value specified by  n.
       If  n  is  omitted,  the return status is that of the last command exe‐
       cuted.

   csh
       exit causes the calling shell or shell script to exit, either with  the
       value of the status variable or with the value specified by the expres‐
       sion expr.


       The goto built-in uses a specified label as  a  search  string  amongst
       commands.  The shell rewinds its input as much as possible and searches
       for a line of the form label: possibly preceded by space or tab charac‐
       ters.  Execution  continues after the indicated line. It is an error to
       jump to a label that occurs between a while or for built-in command and
       its corresponding end.

   ksh88
       exit  causes  the  calling  shell or shell script to exit with the exit
       status specified by n. The value is the least significant 8 bits of the
       specified  status.  If n is omitted then the exit status is that of the
       last command executed. When exit occurs when executing a trap, the last
       command  refers  to  the  command  that  executed  before  the trap was
       invoked. An end-of-file also causes the shell  to  exit  except  for  a
       shell which has the ignoreeof option (See set below) turned on.


       return  causes a shell function or '.' script to return to the invoking
       script with the return status specified by n. The value  is  the  least
       significant  8  bits  of the specified status. If n is omitted then the
       return status is that of  the  last  command  executed.  If  return  is
       invoked while not in a function or a '.' script, then it is the same as
       an exit.


       On this man page, ksh88(1) commands that are preceded by one or  two  *
       (asterisks) are treated specially in the following ways:

           1.     Variable  assignment  lists  preceding the command remain in
                  effect when the command completes.


           2.     I/O redirections are processed after variable assignments.


           3.     Errors cause a script that contains them to abort.


           4.     Words, following a command preceded by ** that  are  in  the
                  format  of a variable assignment, are expanded with the same
                  rules as a variable assignment. This means that  tilde  sub‐
                  stitution  is  performed after the = sign and word splitting
                  and file name generation are not performed.



   ksh
       exit is shell special built-in that causes the shell that invokes it to
       exit. Before exiting the shell, if the EXIT trap is set, it is invoked.


       If n is specified, it is used to set the exit status.


       return  is  a  shell  special  built-in that causes the function or dot
       script that invokes it to exit. If return is invoked outside of a func‐
       tion or dot script it is equivalent to exit.


       If  return  is  invoked  inside  a  function  defined with the function
       reserved word syntax, then any EXIT trap set  within  the  function  is
       invoked in the context of the caller before the function returns.


       If n is specified, it is used to set the exit status.


       On  this  manual  page,  ksh commands that are preceded by one or two +
       symbols are special built-in commands and are treated specially in  the
       following ways:

           1.     Variable  assignment  lists  preceding the command remain in
                  effect when the command completes.


           2.     I/O redirections are processed after variable assignments.


           3.     Errors cause a script that contains them to abort.


           4.     They are not valid function names.


           5.     Words following a command preceded by ++  that  are  in  the
                  format  of  a variable assignment are expanded with the same
                  rules as a variable assignment. This means that  tilde  sub‐
                  stitution  is performed after the = sign and field splitting
                  and file name generation are not performed.



EXIT STATUS
   ksh
       If n is specified for exit, the exit status is  the  least  significant
       eight  bits  of  the value of n. Otherwise, the exit status is the exit
       status of preceding command. When invoked inside a trap, the  preceding
       command means the command that invoked the trap.


       If  n is specified for return, the exit status is the least significant
       eight bits of the value of n. Otherwise, the exit status  is  the  exit
       status of preceding command.
