User Commands                                            break(1)



NAME
     break, continue - shell built-in functions to escape from or
     advance  within  a controlling while, for, foreach, or until
     loop

SYNOPSIS
  sh
     break [n]


     continue [n]


  csh
     break


     continue


  ksh
     *break [n]


     *continue [n]


  ksh93
     +break [n]


     +continue [n]


DESCRIPTION
  sh
     The break utility exits from  the  enclosing  for  or  while
     loop, if any. If n is specified, break n levels.


     The continue utility  resumes  the  next  iteration  of  the
     enclosing  for  or  while loop. If n is specified, resume at
     the n-th enclosing loop.

  csh
     The break utility resumes execution after  the  end  of  the
     nearest  enclosing foreach or while loop. The remaining com-
     mands on the current line are  executed.  This  allows  mul-
     tilevel  breaks  to  be written as a list of break commands,
     all on one line.

User Commands                                            break(1)



     The continue utility continues execution of the next  itera-
     tion of the nearest enclosing while or foreach loop.

  ksh
     The break utility exits from the enclosed for, while, until,
     or select loop, if any. If n is specified, then break n lev-
     els. If n is greater than the number of enclosing loops, the
     outermost enclosing loop shall be exited.


     The continue utility  resumes  the  next  iteration  of  the
     enclosed  for,  while, until, or select loop. If n is speci-
     fied then resume at the n-th enclosed loop. If n is  greater
     than  the number of enclosing loops, the outermost enclosing
     loop shall be used.


     On this manual page, ksh(1) commands that  are  preceded  by
     one  or  two * (asterisks) are treated specially in the fol-
     lowing 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 that follow 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 also that word splitting  and  file
              name generation are not performed.

  ksh93
     break is a shell special built-in that  exits  the  smallest
     enclosing  for,  select, while, or until loop. It also exits
     the nth enclosing loop if n is specified. Execution  contin-
     ues at the command following the loop or loops.


     If n is specified, it must be a positive integer >1. If n is
     larger  than the number of enclosing loops, the last enclos-
     ing loop is exited.


     continue is a shell special built-in that  continues  execu-
     tion  at  the  top  of  the  smallest enclosing for, select,
     while, or until loop, if any; or  of  the  top  of  the  nth
     enclosing loop if n is specified.

User Commands                                            break(1)

     On this manual page, ksh93(1) commands that are preceded  by
     one  or  two + symbols are special built-in commands and are
     treated 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.   Built-in commands are not valid function names.

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