Starting bash with the `-posix' command-line option or setting the variable
POSIXLY_CORRECT 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.
Bash POSIX Mode
===============
The following list is what's changed when `posixly_correct' is enabled:
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.
1. When a command in the hash table no longer exists, bash will re-search
$PATH to find the new location.
The following list is what's changed when `POSIX mode' is in effect:
2. The >& redirection does not redirect stdout and stderr.
1. When a command in the hash table no longer exists, Bash will
re-search `$PATH' to find the new location. This is also
available with `shopt -s checkhash'.
3. The message printed by the job control code and builtins when a job
exits with a non-zero status is `Done(status)'.
2. The `>&' redirection does not redirect stdout and stderr.
4. The <> redirection does not open a file for both stdin and stdout, but
rather opens it for read-write on fd 0.
3. The message printed by the job control code and builtins when a job
exits with a non-zero status is `Done(status)'.
5. Reserved words may not be aliased.
4. Reserved words may not be aliased.
6. The Posix.2 PS1 and PS2 expansions of `!' -> history number and `!!' -> `!'
are enabled.
5. The POSIX.2 `PS1' and `PS2' expansions of `!' to the history
number and `!!' to `!' are enabled, and parameter expansion is
performed on the value regardless of the setting of the
`promptvars' option.
7. Interactive comments are enabled by default. (Note that this version has
them on by default anyway.)
6. Interactive comments are enabled by default. (Note that Bash has
them on by default anyway.)
8. The Posix.2 startup files are executed ($ENV) rather than the normal bash
files.
7. The POSIX.2 startup files are executed (`$ENV') rather than the
normal Bash files.
9. Tilde expansion is only performed on assignments preceding a command name,
rather than on all assignment statements on the line.
8. Tilde expansion is only performed on assignments preceding a
command name, rather than on all assignment statements on the line.
10. The default history file is ~/.sh_history (default value of $HISTFILE).
9. The default history file is `~/.sh_history' (this is the default
value of `$HISTFILE').
11. The output of `kill -l' prints all the signal names on a single line,
separated by spaces.
10. The output of `kill -l' prints all the signal names on a single
line, separated by spaces.
12. Non-interactive shells exit if `file' in `. file' is not found.
11. Non-interactive shells exit if FILENAME in `.' FILENAME is not
found.
13. Redirection operators do not perform pathname expansion on the word
in the redirection unless the shell is interactive
12. Redirection operators do not perform filename expansion on the word
in the redirection unless the shell is interactive.
14. 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
13. Function names must be valid shell `name's. 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.
There is other Posix.2 behavior that bash does not implement. Specifically:
14. POSIX.2 `special' builtins are found before shell functions during
command lookup.
1. There are no `special builtins' and `regular builtins'. All builtins
are equivalent. This means that:
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.
o assignment statements affect the execution environment of all
builtins, not just special ones
o temporary assignments do not persist after Posix.2 special
builtins complete
o Functions are found before Posix.2 special builtins
o The shell does not exit upon errors while executing Posix.2
special builtins
16. If the `cd' builtin finds a directory to change to using
`$CDPATH', the value it assigns to the `PWD' variable does not
contain any symbolic links, as if `cd -P' had been executed.
2. $LINENO does not represent the line number of a command within a function
17. 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.
18. 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.
19. Process substitution is not available.
20. 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.
3. The arithmetic evaluator does not implement the `e ? e1 : e2' conditional
expression

Notes:
ISC 386 machines must compile test.c without -O. The resultant shell dumps
core when test is invoked.
There have been reports that SCO 3.2v4.2 requires -DPRGP_PIPE in SCO_CFLAGS,

It would be nice to have a general completion feature like this.
Until that happens, maybe you will find the following patch useful.
It makes MH folder name completion work with bash. The diffs are
relative to version 1.14.2.
I realize that changes to readline.c and and complete.c are not good
since they add some MH-specific stuff to the readline code and not to
bash, but when I first wrote this, I had no idea what else to do.
Chet, would you consider adding this if it were cleaned up a bit?
Made optional with cpp conditionals?
This feature has been very useful to me for the last several years
(since about 1.05 or 1.06, I think).
Thanks,
