212 File::Glob::bsd_glob() implements the FreeBSD glob(3) routine, which is
213 a superset of the POSIX glob() (described in IEEE Std 1003.2 "POSIX.2").
214 bsd_glob() takes a mandatory C<pattern> argument, and an optional
215 C<flags> argument, and returns a list of filenames matching the
216 pattern, with interpretation of the pattern modified by the C<flags>
219 Since v5.6.0, Perl's CORE::glob() is implemented in terms of bsd_glob().
220 Note that they don't share the same prototype--CORE::glob() only accepts
221 a single argument. Due to historical reasons, CORE::glob() will also
222 split its argument on whitespace, treating it as multiple patterns,
223 whereas bsd_glob() considers them as one pattern.
225 The POSIX defined flags for bsd_glob() are:
231 Force bsd_glob() to return an error when it encounters a directory it
232 cannot open or read. Ordinarily bsd_glob() continues to find matches.
236 Each pathname that is a directory that matches the pattern has a slash
241 By default, file names are assumed to be case sensitive; this flag
242 makes bsd_glob() treat case differences as not significant.
244 =item C<GLOB_NOCHECK>
246 If the pattern does not match any pathname, then bsd_glob() returns a list
247 consisting of only the pattern. If C<GLOB_QUOTE> is set, its effect
248 is present in the pattern returned.
252 By default, the pathnames are sorted in ascending ASCII order; this
253 flag prevents that sorting (speeding up bsd_glob()).
257 The FreeBSD extensions to the POSIX standard are the following flags:
263 Pre-process the string to expand C<{pat,pat,...}> strings like csh(1).
264 The pattern '{}' is left unexpanded for historical reasons (and csh(1)
265 does the same thing to ease typing of find(1) patterns).
267 =item C<GLOB_NOMAGIC>
269 Same as C<GLOB_NOCHECK> but it only returns the pattern if it does not
270 contain any of the special characters "*", "?" or "[". C<NOMAGIC> is
271 provided to simplify implementing the historic csh(1) globbing
272 behaviour and should probably not be used anywhere else.
276 Use the backslash ('\') character for quoting: every occurrence of a
277 backslash followed by a character in the pattern is replaced by that
278 character, avoiding any special interpretation of the character.
279 (But see below for exceptions on DOSISH systems).
283 Expand patterns that start with '~' to user name home directories.
287 For convenience, C<GLOB_CSH> is a synonym for
288 C<GLOB_BRACE | GLOB_NOMAGIC | GLOB_QUOTE | GLOB_TILDE>.
292 The POSIX provided C<GLOB_APPEND>, C<GLOB_DOOFFS>, and the FreeBSD
293 extensions C<GLOB_ALTDIRFUNC>, and C<GLOB_MAGCHAR> flags have not been
294 implemented in the Perl version because they involve more complex
295 interaction with the underlying C structures.
299 bsd_glob() returns a list of matching paths, possibly zero length. If an
300 error occurred, &File::Glob::GLOB_ERROR will be non-zero and C<$!> will be
301 set. &File::Glob::GLOB_ERROR is guaranteed to be zero if no error occurred,
302 or one of the following values otherwise:
306 =item C<GLOB_NOSPACE>
308 An attempt to allocate memory failed.
312 The glob was stopped because an error was encountered.
316 In the case where bsd_glob() has found some matching paths, but is
317 interrupted by an error, it will return a list of filenames B<and>
318 set &File::Glob::ERROR.
320 Note that bsd_glob() deviates from POSIX and FreeBSD glob(3) behaviour
321 by not considering C<ENOENT> and C<ENOTDIR> as errors - bsd_glob() will
322 continue processing despite those errors, unless the C<GLOB_ERR> flag is
325 Be aware that all filenames returned from File::Glob are tainted.
333 If you want to use multiple patterns, e.g. C<bsd_glob "a* b*">, you should
334 probably throw them in a set as in C<bsd_glob "{a*,b*}">. This is because
335 the argument to bsd_glob() isn't subjected to parsing by the C shell.
336 Remember that you can use a backslash to escape things.
340 On DOSISH systems, backslash is a valid directory separator character.
341 In this case, use of backslash as a quoting character (via GLOB_QUOTE)
342 interferes with the use of backslash as a directory separator. The
343 best (simplest, most portable) solution is to use forward slashes for
344 directory separators, and backslashes for quoting. However, this does
345 not match "normal practice" on these systems. As a concession to user
346 expectation, therefore, backslashes (under GLOB_QUOTE) only quote the
347 glob metacharacters '[', ']', '{', '}', '-', '~', and backslash itself.
348 All other backslashes are passed through unchanged.
352 Win32 users should use the real slash. If you really want to use
353 backslashes, consider using Sarathy's File::DosGlob, which comes with
354 the standard Perl distribution.
