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]

]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.

ing loop is used.
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.
