 | |
| cindex(options, specifying)
 | |
| Options are primarily referred to by name.
 | |
| These names are case insensitive and underscores are ignored.
 | |
| For example, `tt(allexport)' is equivalent to `tt(A__lleXP_ort)'.
 | |
| 
 | |
| The sense of an option name may be inverted by preceding it with
 | |
| `tt(no)', so `tt(setopt No_Beep)' is equivalent to `tt(unsetopt beep)'.
 | |
| This inversion can only be done once, so `tt(nonobeep)' is em(not)
 | |
| a synonym for `tt(beep)'.  Similarly, `tt(tify)' is not a synonym for
 | |
| `tt(nonotify)' (the inversion of `tt(notify)').
 | |
| 
 | |
| Some options also have one or more single letter names.
 | |
| There are two sets of single letter options: one used by default,
 | |
| and another used to emulate bf(sh)/bf(ksh) (used when the
 | |
| tt(SH_OPTION_LETTERS) option is set).
 | |
| The single letter options can be used on the shell command line,
 | |
| or with the tt(set), tt(setopt) and tt(unsetopt)
 | |
| builtins, as normal Unix options preceded by `tt(-)'.
 | |
| 
 | |
| The sense of the single letter options may be inverted by using
 | |
| `tt(PLUS())' instead of `tt(-)'.
 | |
| Some of the single letter option names refer to an option being off,
 | |
| in which case the inversion of that name refers to the option being on.
 | |
| For example, `tt(PLUS()n)' is the short name of `tt(exec)', and
 | |
| `tt(-n)' is the short name of its inversion, `tt(noexec)'.
 | |
| 
 | |
| In strings of single letter options supplied to the shell at startup,
 | |
| trailing whitespace will be ignored; for example the string `tt(-f    )'
 | |
| will be treated just as `tt(-f)', but the string `tt(-f i)' is an error.
 | |
| This is because many systems which implement the `tt(#!)' mechanism for
 | |
| calling scripts do not strip trailing whitespace.

| cindex(options, description)
 | |
| In the following list, options set by default in all emulations are marked
 | |
| <D>; those set by default only in csh, ksh, sh, or zsh emulations are marked
 | |
| <C>, <K>, <S>, <Z> as appropriate.  When listing options (by `tt(setopt)',
 | |
| `tt(unsetopt)', `tt(set -o)' or `tt(set +o)'), those turned on by default
 | |
| appear in the list prefixed with `tt(no)'.  Hence (unless
 | |
| tt(KSH_OPTION_PRINT) is set), `tt(setopt)' shows all options whose settings
 | |
| are changed from the default.
