exit(1)

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

  ksh
     *exit [n]

     *return [n]

DESCRIPTION

  sh
     exit will cause 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
     will also cause 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 executed.

  csh
     exit will cause the calling shell or shell script  to  exit,
     either  with  the  value  of the status variable or with the
     value specified by the expression 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 characters. 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.

  ksh
     exit will cause the calling shell or shell  script  to  exit
     with  the  exit status specified by n. The value will be 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 will also cause  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 will be the least significant 8 bits of the speci-
     fied 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, ksh(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  assign-
        ments.

     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 substitution is performed after the = sign and word
        splitting and file name generation are not performed.
