Starting bash with the `--posix' command-line option or executing
`set -o posix' while bash is running will cause bash to conform more
closely to the Posix.2 standard by changing the behavior to match that
specified by Posix.2 in areas where the bash default differs.
The following list is what's changed when `posix mode' is in effect:
1. When a command in the hash table no longer exists, bash will re-search
$PATH to find the new location. This is also available with
`shopt -s checkhash'.
2. The >& redirection does not redirect stdout and stderr.
3. The message printed by the job control code and builtins when a job
exits with a non-zero status is `Done(status)'.
4. Reserved words may not be aliased.
5. The Posix.2 PS1 and PS2 expansions of `!' -> history number and
`!!' -> `!' are enabled, and parameter expansion is performed on
the value regardless of the setting of the `promptvars' option.
6. Interactive comments are enabled by default. (Note that bash has
them on by default anyway.)
7. The Posix.2 startup files are executed ($ENV) rather than the normal
bash files.
8. Tilde expansion is only performed on assignments preceding a command
name, rather than on all assignment statements on the line.
9. The default history file is ~/.sh_history (default value of $HISTFILE).
10. The output of `kill -l' prints all the signal names on a single line,
separated by spaces.
11. Non-interactive shells exit if `file' in `. file' is not found.
12. Redirection operators do not perform pathname expansion on the word
in the redirection unless the shell is interactive
13. Function names must be valid shell identifiers. That is, they may not
contain characters other than letters, digits, and underscores, and
may not start with a digit. Declaring a function with an illegal name
causes a fatal syntax error in non-interactive shells.
14. Posix.2 `special' builtins are found before shell functions during command
lookup.
15. If a Posix.2 special builtin returns an error status, a non-interactive
shell exits. The fatal errors are those listed in the POSIX.2 standard,
and include things like passing incorrect options, redirection errors,
variable assignment errors for assignments preceding the command name,
and so on.
16. The environment passed to executed commands is not sorted. Neither is
the output of `set'. This is not strictly Posix.2 behavior, but sh
does it this way. Ksh does not. It's not necessary to sort the
environment; no program should rely on it being sorted.
17. If the `cd' builtin finds a directory to change to using $CDPATH, the
value it assigns to $PWD does not contain any symbolic links, as if
`cd -P' had been executed.
18. A non-interactive shell exits with an error status if a variable
assignment error occurs when no command name follows the assignment
statements. A variable assignment error occurs, for example, when
trying to assign a value to a read-only variable.
19. A non-interactive shell exits with an error status if the iteration
variable in a for statement or the selection variable in a select
statement is a read-only variable.
20. Process substitution is not available.
21. Assignment statements preceding POSIX.2 `special' builtins persist in
the shell environment after the builtin completes.
There is other Posix.2 behavior that bash does not implement. Specifically:
1. Assignment statements affect the execution environment of all builtins,
not just special ones.

-a Mark variables which are modified or created for export.
-b Notify of job termination immediately.
-e Exit immediately if a command exits with a non-zero status.
-f Disable file name generation (globbing).
-h Locate and remember function commands as functions are
defined. Function commands are normally looked up when
the function is executed.
-i Force the shell to be an "interactive" one. Interactive shells
always read `~/.bashrc' on startup.
-k All keyword arguments are placed in the environment for a
command, not just those that precede the command name.
-m Job control is enabled.
-n Read commands but do not execute them.
-o option-name
Set the variable corresponding to option-name:
allexport same as -a
braceexpand same as -B
#if defined (READLINE)
emacs use an emacs-style line editing interface
#endif /* READLINE */
errexit same as -e
histexpand same as -H
ignoreeof the shell will not exit upon reading EOF
interactive-comments
allow comments to appear in interactive commands
monitor same as -m
noclobber disallow redirection to existing files
noexec same as -n
noglob same as -f
nohash same as -d
notify save as -b
nounset same as -u
physical same as -P
posix change the behavior of bash where the default
operation differs from the 1003.2 standard to
match the standard
privileged same as -p
verbose same as -v
#if defined (READLINE)
vi use a vi-style line editing interface
#endif /* READLINE */
xtrace same as -x
-p Turned on whenever the real and effective user ids do not match.
Disables processing of the $ENV file and importing of shell
functions. Turning this option off causes the effective uid and
gid to be set to the real uid and gid.
-t Exit after reading and executing one command.
-u Treat unset variables as an error when substituting.
-v Print shell input lines as they are read.
-x Print commands and their arguments as they are executed.
-l Save and restore the binding of the NAME in a FOR command.
-d Disable the hashing of commands that are looked up for execution.
Normally, commands are remembered in a hash table, and once
found, do not have to be looked up again.
#if defined (BRACE_EXPANSION)
-B the shell will perform brace expansion
#endif /* BRACE_EXPANSION */
#if defined (BANG_HISTORY)
-H Enable ! style history substitution. This flag is on
by default.
#endif /* BANG_HISTORY */
-C If set, disallow existing regular files to be overwritten
by redirection of output.
-P If set, do not follow symbolic links when executing commands
such as cd which change the current directory.
Using + rather than - causes these flags to be turned off. The
flags can also be used upon invocation of the shell. The current
set of flags may be found in $-. The remaining n ARGs are positional
parameters and are assigned, in order, to $1, $2, .. $n. If no
ARGs are given, all shell variables are printed.

Specify how arguments are to be completed by Readline.
For each NAME, specify how arguments are to be completed. If no options
are supplied, existing completion specifications are printed in a way that
allows them to be reused as input.
Options:
-p print existing completion specifications in a reusable format
-r remove a completion specification for each NAME, or, if no
NAMEs are supplied, all completion specifications
-D apply the completions and actions as the default for commands
without any specific completion defined
-E apply the completions and actions to "empty" commands --
completion attempted on a blank line
When completion is attempted, the actions are applied in the order the
uppercase-letter options are listed above. The -D option takes
precedence over -E.
Exit Status:
Returns success unless an invalid option is supplied or an error occurs.

Modify or display completion options.
Modify the completion options for each NAME, or, if no NAMEs are supplied,
the completion currently being executed. If no OPTIONs are given, print
the completion options for each NAME or the current completion specification.
Options:
-o option Set completion option OPTION for each NAME
-D Change options for the "default" command completion
-E Change options for the "empty" command completion
Using `+o' instead of `-o' turns off the specified option.
Arguments:
Each NAME refers to a command for which a completion specification must
have previously been defined using the `complete' builtin. If no NAMEs
are supplied, compopt must be called by a function currently generating
completions, and the options for that currently-executing completion
generator are modified.
Exit Status:
Returns success unless an invalid option is supplied or NAME does not
have a completion specification defined.

$FUNCTION umask_builtin
$SHORT_DOC umask [-p] [-S] [mode]
Display or set file mode mask.
Sets the user file-creation mask to MODE. If MODE is omitted, prints
the current value of the mask.
If MODE begins with a digit, it is interpreted as an octal number;
otherwise it is a symbolic mode string like that accepted by chmod(1).
Options:
-p if MODE is omitted, output in a form that may be reused as input
-S makes the output symbolic; otherwise an octal number is output
Exit Status:
Returns success unless MODE is invalid or an invalid option is given.
