122 utility creates and maintains groups of files combined into an
124 Once an archive has been created, new files can be added to it, and
125 existing files can be extracted, deleted or replaced.
127 Files are named in the archive by their last file name component,
128 so if a file referenced by a path containing a
130 is archived, it will be named by the last component of the path.
131 Similarly when matching paths listed on the command line against
132 file names stored in the archive, only the last component of the
133 path will be compared.
137 is for the creation and maintenance of libraries suitable for use
140 although it is not restricted to this purpose.
143 utility can create and manage an archive symbol table (see
145 used to speed up link editing operations.
146 If a symbol table is present in an archive, it will be
147 kept up-to-date by subsequent operations on the archive.
151 utility is used to add an archive symbol table
152 to an existing archive.
156 utility supports the following options:
157 .Bl -tag -width indent
158 .It Fl a Ar member-after
159 When used with option
161 this option specifies that the archive members specified by
164 are moved to after the archive member named by argument
166 When used with option
168 this option specifies that the files specified by arguments
170 are added after the archive member named by argument
172 .It Fl b Ar member-before
173 When used with option
175 this option specifies that the archive members specified by
178 are moved to before the archive member named by argument
180 When used with option
182 this option specifies that the files specified by arguments
184 are added before the archive member named by argument
187 Suppress the informational message printed when a new archive is
194 Prevent extracted files from replacing like-named files
197 Delete the members named by arguments
199 from the archive specified by argument
201 The archive's symbol table, if present, is updated to reflect
202 the new contents of the archive.
204 When used in combination with the
211 option without other options, or when invoked as
213 insert 0's instead of the real mtime, uid and gid values
214 and 0644 instead of file mode from the members named by arguments
216 This ensures that checksums on the resulting archives are reproducible
217 when member contents are identical.
218 This option is enabled by default.
223 options are specified on the command line, the final one takes precedence.
225 Use only the first fifteen characters of the archive member name or
226 command line file name argument when naming archive members.
227 .It Fl i Ar member-before
228 Synonymous with option
231 This option is accepted but ignored.
233 This option is accepted for compatibility with GNU
237 Move archive members specified by arguments
240 If a position has been specified by one of the
245 options, the members are moved to before or after the specified
247 If no position has been specified, the specified members are moved
248 to the end of the archive.
249 If the archive has a symbol table, it is updated to reflect the
250 new contents of the archive.
252 Read and execute MRI librarian commands from standard input.
253 The commands understood by the
255 utility are described in the section
256 .Sx "MRI Librarian Commands" .
258 Preserve the original modification times of members when extracting
261 Write the contents of the specified archive members named by
265 If no members were specified, the contents of all the files in the
266 archive are written in the order they appear in the archive.
268 Append the files specified by arguments
270 to the archive specified by argument
272 without checking if the files already exist in the archive.
273 The archive symbol table will be updated as needed.
274 If the file specified by the argument
276 does not already exist, a new archive will be created.
278 Replace (add) the files specified by arguments
280 in the archive specified by argument
282 creating the archive if necessary.
283 Replacing existing members will not change the order of members within
285 If a file named in arguments
287 does not exist, existing members in the archive that match that
288 name are not changed.
289 New files are added to the end of the archive unless one of the
296 The archive symbol table, if it exists, is updated to reflect the
297 new state of the archive.
299 Add an archive symbol table (see
301 to the archive specified by argument
307 option alone is equivalent to invoking
310 Do not generate an archive symbol table.
312 List the files specified by arguments
314 in the order in which they appear in the archive, one per line.
315 If no files are specified, all files in the archive are listed.
317 This option is accepted but ignored.
318 In other implementations of
321 creates a "thin" archive.
323 Conditionally update the archive or extract members.
326 option, files named by arguments
328 will be replaced in the archive if they are newer than their
332 option, the members specified by arguments
334 will be extracted only if they are newer than the corresponding
335 files in the file system.
337 When used in combination with the
341 option, insert the real mtime, uid and gid, and file mode values
342 from the members named by arguments
348 options are specified on the command line, the final one takes precedence.
350 Provide verbose output.
359 gives a file-by-file description of the archive modification being
360 performed, which consists of three white-space separated fields:
361 the option letter, a dash
368 displays the description as above, but the initial letter is an
370 if the file is added to the archive, or an
372 if the file replaces a file already in the archive.
375 option, the name of the file enclosed in
379 characters is written to standard output preceded by a single newline
380 character and followed by two newline characters.
381 The contents of the named file follow the file name.
386 displays eight whitespace separated fields:
387 the file permissions as displayed by
389 decimal user and group IDs separated by a slash (
391 the file size in bytes, the file modification time in
394 .Dq "%b %e %H:%M %Y" ,
395 and the name of the file.
397 Print a version string and exit.
399 Extract archive members specified by arguments
401 into the current directory.
402 If no members have been specified, extract all members of the archive.
403 If the file corresponding to an extracted member does not exist it
405 If the file corresponding to an extracted member does exist, its owner
406 and group will not be changed while its contents will be overwritten
407 and its permissions will set to that entered in the archive.
408 The file's access and modification time would be that of the time
409 of extraction unless the
411 option was specified.
413 This option is accepted but ignored.
415 .Ss "MRI Librarian Commands"
418 option is specified, the
420 utility will read and execute commands from its standard input.
421 If standard input is a terminal, the
423 utility will display the prompt
425 before reading a line, and will continue operation even if errors are
427 If standard input is not a terminal, the
429 utility will not display a prompt and will terminate execution on
430 encountering an error.
432 Each input line contains a single command.
433 Words in an input line are separated by whitespace characters.
434 The first word of the line is the command, the remaining words are
435 the arguments to the command.
436 The command word may be specified in either case.
437 Arguments may be separated by commas or blanks.
439 Empty lines are allowed and are ignored.
440 Long lines are continued by ending them with the
448 characters start a comment.
449 Comments extend till the end of the line.
451 When executing an MRI librarian script the
453 utility works on a temporary copy of an archive.
454 Changes to the copy are made permanent using the
458 Commands understood by the
