126 utility creates and maintains groups of files combined into an
128 Once an archive has been created, new files can be added to it, and
129 existing files can be extracted, deleted or replaced.
131 Files are named in the archive by their last file name component,
132 so if a file referenced by a path containing a
134 is archived, it will be named by the last component of the path.
135 Similarly when matching paths listed on the command line against
136 file names stored in the archive, only the last component of the
137 path will be compared.
141 is for the creation and maintenance of libraries suitable for use
144 although it is not restricted to this purpose.
147 utility can create and manage an archive symbol table (see
149 used to speed up link editing operations.
150 If a symbol table is present in an archive, it will be
151 kept up-to-date by subsequent operations on the archive.
155 utility supports the following options:
156 .Bl -tag -width indent
157 .It Fl a Ar member-after
158 When used with option
160 this option specifies that the archive members specified by
163 are moved to after the archive member named by argument
165 When used with option
167 this option specifies that the files specified by arguments
169 are added after the archive member named by argument
171 .It Fl b Ar member-before
172 When used with option
174 this option specifies that the archive members specified by
177 are moved to before the archive member named by argument
179 When used with option
181 this option specifies that the files specified by arguments
183 are added before the archive member named by argument
186 Suppress the informational message printed when a new archive is
193 Prevent extracted files from replacing like-named files
196 Delete the members named by arguments
198 from the archive specified by argument
200 The archive's symbol table, if present, is updated to reflect
201 the new contents of the archive.
203 When used in combination with the
207 option, insert 0's instead of the real mtime, uid and gid values
208 and 0644 instead of file mode from the members named by arguments
210 This ensures that checksums on the resulting archives are reproducible
211 when member contents are identical.
216 options are specified on the command line, the final one takes precedence.
218 Synonymous with option
220 .It Fl F Ar flavor | Fl -flavor Ar flavor
221 Create archives with the specified archive format.
222 Legal values for argument
225 .Bl -tag -width indent -compact
227 Create BSD format archives.
232 Create SVR4 format archives.
234 If this option is not specified,
236 will create archives using the SVR4 format.

241 This option is accepted for compatibility with the
245 utility, but is ignored.
247 This option is accepted for compatibility with GNU
251 Move archive members specified by arguments
254 If a position has been specified by one of the
259 options, the members are moved to before or after the specified
261 If no position has been specified, the specified members are moved
262 to the end of the archive.
263 If the archive has a symbol table, it is updated to reflect the
264 new contents of the archive.
266 Read and execute MRI librarian commands from standard input.
267 The commands understood by the
269 utility are described in the section
270 .Sx "MRI Librarian Commands" .
272 Preserve the original modification times of members when extracting
275 Write the contents of the specified archive members named by
279 If no members were specified, the contents of all the files in the
280 archive are written in the order they appear in the archive.
282 Append the files specified by arguments
284 to the archive specified by argument
286 without checking if the files already exist in the archive.
287 The archive symbol table will be updated as needed.
288 If the file specified by the argument
290 does not already exist, a new archive will be created.
292 Replace (add) the files specified by arguments
294 in the archive specified by argument
296 creating the archive if necessary.
297 Replacing existing members will not change the order of members within
299 If a file named in arguments
301 does not exist, existing members in the archive that match that
302 name are not changed.
303 New files are added to the end of the archive unless one of the

311 new state of the archive.
313 Add an archive symbol table (see
315 to the archive specified by argument
321 option alone is equivalent to invoking
324 Do not generate an archive symbol table.
328 list the files specified by arguments
330 in the order in which they appear in the archive, one per line.
331 If no files are specified, all files in the archive are listed.
333 Use only the first fifteen characters of the archive member name or
334 command line file name argument when naming archive members.
336 Conditionally update the archive or extract members.
339 option, files named by arguments
341 will be replaced in the archive if they are newer than their
345 option, the members specified by arguments
347 will be extracted only if they are newer than the corresponding
348 files in the file system.
350 When used in combination with the
354 option, insert the real mtime, uid and gid, and file mode values
355 from the members named by arguments
361 options are specified on the command line, the final one takes precedence.
363 Provide verbose output.
372 gives a file-by-file description of the archive modification being
373 performed, which consists of three white-space separated fields:
374 the option letter, a dash
381 displays the description as above, but the initial letter is an
383 if the file is added to the archive, or an
385 if the file replaces a file already in the archive.
388 option, the name of the file enclosed in
392 characters is written to standard output preceded by a single newline
393 character and followed by two newline characters.
394 The contents of the named file follow the file name.
399 displays eight whitespace separated fields:
400 the file permissions as displayed by
402 decimal user and group IDs separated by a slash (
404 the file size in bytes, the file modification time in
407 .Dq "%b %e %H:%M %Y" ,
408 and the name of the file.
410 Print a version identifier and exit.
412 Extract archive members specified by arguments
414 into the current directory.
415 If no members have been specified, extract all members of the archive.
416 If the file corresponding to an extracted member does not exist it
418 If the file corresponding to an extracted member does exist, its owner
419 and group will not be changed while its contents will be overwritten
420 and its permissions will set to that entered in the archive.
421 The file's access and modification time would be that of the time
422 of extraction unless the
424 option was specified.
426 This option is accepted for compatibility with the
430 utility, but is ignored.
432 .Ss "MRI Librarian Commands"
435 option is specified, the
437 utility will read and execute commands from its standard input.
438 If standard input is a terminal, the
440 utility will display the prompt
442 before reading a line, and will continue operation even if errors are
444 If standard input is not a terminal, the
446 utility will not display a prompt and will terminate execution on
447 encountering an error.
449 Each input line contains a single command.
450 Words in an input line are separated by whitespace characters.
451 The first word of the line is the command, the remaining words are
452 the arguments to the command.
453 The command word may be specified in either case.
454 Arguments may be separated by commas or blanks.
456 Empty lines are allowed and are ignored.
457 Long lines are continued by ending them with the
465 characters start a comment.
466 Comments extend till the end of the line.
468 When executing an MRI librarian script the
470 utility works on a temporary copy of an archive.
