are distinct (See POSIX.2 glossary).
A utility is a executable, script or shell builtin; while a command
can be any of those things plus lists, pipelines, compound commands
(if, for, while) and shell function definitions.
POSIX.2 requires that if "." or ".." are specified as the basename
portion of an operand, a diagnostic message be written to standard
error, etc. We strip the slashes because POSIX.2 defines basename
as the final portion of a pathname after trailing slashes have been
removed.
This also makes rm "perform actions equivalent to" the POSIX.1
rmdir() and unlink() functions when removing directories and files,
even when they do not follow POSIX.1's pathname resolution semantics
(which require trailing slashes be ignored).
If all the arguments have a "." or ".." basename, the exit value should be
modified whether or not the -f flag was specified.
Don't exit if a file can not be read or there is another error (FTS_DNR or
FTS_ERR), there are probably other files that we can process successfully.
to be a locale specific regular expression. This change hard codes POSIX
locale behavior, and will be replaced by a locale independant equivalent
as soon as locales are fully implemented.
had time to look at the recursive code, but it probably has the same
types of problems.
Added code to set the default locale, so it will work correctly when
our locale code is more than just stubs.
Added prototypes, etc. to make gcc -Wall happier.
