40 The break utility exits from the enclosing for or while loop, if any.
41 If n is specified, break n levels.
42 The continue utility resumes the next iteration of the enclosing for or
45 while loop. If n is specified, resume at the n-th enclosing loop.
46 csh
48 The break utility resumes execution after the end of the nearest
49 enclosing foreach or while loop. The remaining commands on the current
50 line are executed. This allows multilevel breaks to be written as a
51 list of break commands, all on one line.
52 The continue utility continues execution of the next iteration of the
55 nearest enclosing while or foreach loop.
56 ksh
58 The break utility exits from the enclosed for, while, until, or select
59 loop, if any. If n is specified, then break n levels. If n is greater
60 than the number of enclosing loops, the outermost enclosing loop shall
61 be exited.
62 The continue utility resumes the next iteration of the enclosed for,
65 while, until, or select loop. If n is specified then resume at the n-th
66 enclosed loop. If n is greater than the number of enclosing loops, the
67 outermost enclosing loop shall be used.
68 On this manual page, ksh(1) commands that are preceded by one or two *
71 (asterisks) are treated specially in the following ways:
72 1. Variable assignment lists preceding the command remain in
74 effect when the command completes.
75 2. I/O redirections are processed after variable assignments.
77 3. Errors cause a script that contains them to abort.
79 4. Words that follow a command preceded by ** that are in the
81 format of a variable assignment are expanded with the same
82 rules as a variable assignment. This means that tilde sub‐
83 stitution is performed after the = sign, and also that word
84 splitting and file name generation are not performed.
85 ksh93
87 break is a shell special built-in that exits the smallest enclosing
88 for, select, while, or until loop. It also exits the nth enclosing loop
89 if n is specified. Execution continues at the command following the
90 loop or loops.
91 If n is specified, it must be a positive integer ≥1. If n is larger
94 than the number of enclosing loops, the last enclosing loop is exited.
95 continue is a shell special built-in that continues execution at the
98 top of the smallest enclosing for, select, while, or until loop, if
99 any; or of the top of the nth enclosing loop if n is specified.
100 If n is specified, it must be a positive integer ≥1. If n is larger
103 than the number of enclosing loops, the last enclosing loop is used.
104 On this manual page, ksh93(1) commands that are preceded by one or two
107 + symbols are special built-in commands and are treated the following
108 ways:
109 1. Variable assignment lists preceding the command remain in
111 effect when the command completes.
112 2. I/O redirections are processed after variable assignments.
114 3. Errors cause a script that contains them to abort.
116 4. Built-in commands are not valid function names.
118 5. Words following a command preceded by ++ that are in the
120 format of a variable assignment are expanded with rules as a
121 variable assignment. This means that tilde substitution is
122 performed after the = sign and field splitting and file name
123 generation are not performed.
