120 utility creates and maintains groups of files combined into an
122 Once an archive has been created, new files can be added to it, and
123 existing files can be extracted, deleted or replaced.
125 Files are named in the archive by their last file name component,
126 so if a file referenced by a path containing a
128 is archived, it will be named by the last component of the path.
129 Similarly when matching paths listed on the command line against
130 file names stored in the archive, only the last component of the
131 path will be compared.
135 is for the creation and maintenance of libraries suitable for use
138 although it is not restricted to this purpose.
141 utility can create and manage an archive symbol table (see
143 used to speed up link editing operations.
144 If a symbol table is present in an archive, it will be
145 kept up-to-date by subsequent operations on the archive.
149 utility is used to add an archive symbol table
150 to an existing archive.
154 utility supports the following options:
155 .Bl -tag -width indent
156 .It Fl a Ar member-after
157 When used with option
159 this option specifies that the archive members specified by
162 are moved to after the archive member named by argument
164 When used with option
166 this option specifies that the files specified by arguments
168 are added after the archive member named by argument
170 .It Fl b Ar member-before
171 When used with option
173 this option specifies that the archive members specified by
176 are moved to before the archive member named by argument
178 When used with option
180 this option specifies that the files specified by arguments
182 are added before the archive member named by argument
185 Suppress the informational message printed when a new archive is
192 Prevent extracted files from replacing like-named files
195 Delete the members named by arguments
197 from the archive specified by argument
199 The archive's symbol table, if present, is updated to reflect
200 the new contents of the archive.
202 When used in combination with the
209 option without other options, or when invoked as
211 insert 0's instead of the real mtime, uid and gid values
212 and 0644 instead of file mode from the members named by arguments
214 This ensures that checksums on the resulting archives are reproducible
215 when member contents are identical.
216 This option is enabled by default.
221 options are specified on the command line, the final one takes precedence.
223 Use only the first fifteen characters of the archive member name or
224 command line file name argument when naming archive members.
225 .It Fl i Ar member-before
226 Synonymous with option
229 This option is accepted but ignored.
231 This option is accepted for compatibility with GNU
235 Move archive members specified by arguments
238 If a position has been specified by one of the
243 options, the members are moved to before or after the specified
245 If no position has been specified, the specified members are moved
246 to the end of the archive.
247 If the archive has a symbol table, it is updated to reflect the
248 new contents of the archive.
250 Read and execute MRI librarian commands from standard input.
251 The commands understood by the
253 utility are described in the section
254 .Sx "MRI Librarian Commands" .
256 Preserve the original modification times of members when extracting
259 Write the contents of the specified archive members named by
263 If no members were specified, the contents of all the files in the
264 archive are written in the order they appear in the archive.
266 Append the files specified by arguments
268 to the archive specified by argument
270 without checking if the files already exist in the archive.
271 The archive symbol table will be updated as needed.
272 If the file specified by the argument
274 does not already exist, a new archive will be created.
276 Replace (add) the files specified by arguments
278 in the archive specified by argument
280 creating the archive if necessary.
281 Replacing existing members will not change the order of members within
283 If a file named in arguments
285 does not exist, existing members in the archive that match that
286 name are not changed.
287 New files are added to the end of the archive unless one of the
294 The archive symbol table, if it exists, is updated to reflect the
295 new state of the archive.
297 Add an archive symbol table (see
299 to the archive specified by argument
305 option alone is equivalent to invoking
308 Do not generate an archive symbol table.
310 List the files specified by arguments
312 in the order in which they appear in the archive, one per line.
313 If no files are specified, all files in the archive are listed.
315 This option is accepted but ignored.
316 In other implementations of
319 creates a "thin" archive.
321 Conditionally update the archive or extract members.
324 option, files named by arguments
326 will be replaced in the archive if they are newer than their
330 option, the members specified by arguments
332 will be extracted only if they are newer than the corresponding
333 files in the file system.
335 When used in combination with the
339 option, insert the real mtime, uid and gid, and file mode values
340 from the members named by arguments
346 options are specified on the command line, the final one takes precedence.
348 Provide verbose output.
357 gives a file-by-file description of the archive modification being
358 performed, which consists of three white-space separated fields:
359 the option letter, a dash
366 displays the description as above, but the initial letter is an
368 if the file is added to the archive, or an
370 if the file replaces a file already in the archive.
373 option, the name of the file enclosed in
377 characters is written to standard output preceded by a single newline
378 character and followed by two newline characters.
379 The contents of the named file follow the file name.
384 displays eight whitespace separated fields:
385 the file permissions as displayed by
387 decimal user and group IDs separated by a slash (
389 the file size in bytes, the file modification time in
392 .Dq "%b %e %H:%M %Y" ,
393 and the name of the file.
395 Print a version string and exit.
397 Extract archive members specified by arguments
399 into the current directory.
400 If no members have been specified, extract all members of the archive.
401 If the file corresponding to an extracted member does not exist it
403 If the file corresponding to an extracted member does exist, its owner
404 and group will not be changed while its contents will be overwritten
405 and its permissions will set to that entered in the archive.
406 The file's access and modification time would be that of the time
407 of extraction unless the
409 option was specified.
411 This option is accepted but ignored.
413 .Ss "MRI Librarian Commands"
416 option is specified, the
418 utility will read and execute commands from its standard input.
419 If standard input is a terminal, the
421 utility will display the prompt
423 before reading a line, and will continue operation even if errors are
425 If standard input is not a terminal, the
427 utility will not display a prompt and will terminate execution on
428 encountering an error.
430 Each input line contains a single command.
431 Words in an input line are separated by whitespace characters.
432 The first word of the line is the command, the remaining words are
433 the arguments to the command.
434 The command word may be specified in either case.
435 Arguments may be separated by commas or blanks.
437 Empty lines are allowed and are ignored.
438 Long lines are continued by ending them with the
446 characters start a comment.
447 Comments extend till the end of the line.
449 When executing an MRI librarian script the
451 utility works on a temporary copy of an archive.
452 Changes to the copy are made permanent using the
456 Commands understood by the
459 .Bl -tag -width indent
