An \c +.I archive\c +\& is a single file holding a collection of +other files in a structure that makes it possible to retrieve +the original individual files (called \c +.I members\c +\& of the archive). + +The original files' contents, mode (permissions), timestamp, owner, and +group are preserved in the archive, and may be reconstituted on +extraction. + +GNU \c +.B ar\c +\& can maintain archives whose members have names of any +length; however, depending on how \c +.B ar\c +\& is configured on your +system, a limit on member-name length may be imposed (for compatibility +with archive formats maintained with other tools). If it exists, the +limit is often 15 characters (typical of formats related to a.out) or 16 +characters (typical of formats related to coff). + +\c +.B ar\c +\& is considered a binary utility because archives of this sort +are most often used as \c +.I libraries\c +\& holding commonly needed +subroutines. + +\c +.B ar\c +\& will create an index to the symbols defined in relocatable +object modules in the archive when you specify the modifier `\|\c +.B s\c +\|'. +Once created, this index is updated in the archive whenever \c +.B ar\c +\& +makes a change to its contents (save for the `\|\c +.B q\c +\|' update operation). +An archive with such an index speeds up linking to the library, and +allows routines in the library to call each other without regard to +their placement in the archive. + +You may use `\|\c +.B nm \-s\c +\|' or `\|\c +.B nm \-\-print\-armap\c +\|' to list this index +table. If an archive lacks the table, another form of \c +.B ar\c +\& called +\c +.B ranlib\c +\& can be used to add just the table. + +\c +.B ar\c +\& insists on at least two arguments to execute: one +keyletter specifying the \c +.I operation\c +\& (optionally accompanied by other +keyletters specifying \c +.I modifiers\c +\&), and the archive name to act on. + +Most operations can also accept further \c +.I files\c +\& arguments, +specifying particular files to operate on. + +.SH OPTIONS +GNU \c +.B ar\c +\& allows you to mix the operation code \c +.I p\c +\& and modifier +flags \c +.I mod\c +\& in any order, within the first command-line argument. + +If you wish, you may begin the first command-line argument with a +dash. + +The \c +.I p\c +\& keyletter specifies what operation to execute; it may be +any of the following, but you must specify only one of them: + +.TP +.B d +\c +.I Delete\c +\& modules from the archive. Specify the names of modules to +be deleted as \c +.I files\c +\&; the archive is untouched if you +specify no files to delete. + +If you specify the `\|\c +.B v\c +\|' modifier, \c +.B ar\c +\& will list each module +as it is deleted. + +.TP +.B m +Use this operation to \c +.I move\c +\& members in an archive. + +The ordering of members in an archive can make a difference in how +programs are linked using the library, if a symbol is defined in more +than one member. + +If no modifiers are used with \c +.B m\c +\&, any members you name in the +\c +.I files\c +\& arguments are moved to the \c +.I end\c +\& of the archive; +you can use the `\|\c +.B a\c +\|', `\|\c +.B b\c +\|', or `\|\c +.B i\c +\|' modifiers to move them to a +specified place instead. + +.TP +.B p +\c +.I Print\c +\& the specified members of the archive, to the standard +output file. If the `\|\c +.B v\c +\|' modifier is specified, show the member +name before copying its contents to standard output. + +If you specify no \c +.I files\c +\&, all the files in the archive are printed. + +.TP +.B q +\c +.I Quick append\c +\&; add \c +.I files\c +\& to the end of \c +.I archive\c +\&, +without checking for replacement. + +The modifiers `\|\c +.B a\c +\|', `\|\c +.B b\c +\|', and `\|\c +.B i\c +\|' do \c +.I not\c +\& affect this +operation; new members are always placed at the end of the archive. + +The modifier `\|\c +.B v\c +\|' makes \c +.B ar\c +\& list each file as it is appended. + +Since the point of this operation is speed, the archive's symbol table +index is not updated, even if it already existed; you can use `\|\c +.B ar s\c +\|' or +\c +.B ranlib\c +\& explicitly to update the symbol table index. + +However, too many different systems assume quick append rebuilds the +index, so GNU +.B ar +implements `\|\c +.B q\c +\|' as a synonym for `\|\c +.B r\c +\|'. + +.TP +.B r +Insert \c +.I files\c +\& into \c +.I archive\c +\& (with \c +.I replacement\c +\&). This +operation differs from `\|\c +.B q\c +\|' in that any previously existing members +are deleted if their names match those being added. + +If one of the files named in \c +.I files\c +\& doesn't exist, \c +.B ar\c +\& +displays an error message, and leaves undisturbed any existing members +of the archive matching that name. + +By default, new members are added at the end of the file; but you may +use one of the modifiers `\|\c +.B a\c +\|', `\|\c +.B b\c +\|', or `\|\c +.B i\c +\|' to request +placement relative to some existing member. + +The modifier `\|\c +.B v\c +\|' used with this operation elicits a line of +output for each file inserted, along with one of the letters `\|\c +.B a\c +\|' or +`\|\c +.B r\c +\|' to indicate whether the file was appended (no old member +deleted) or replaced. + +.TP +.B t +Display a \c +.I table\c +\& listing the contents of \c +.I archive\c +\&, or those +of the files listed in \c +.I files\c +\& that are present in the +archive. Normally only the member name is shown; if you also want to +see the modes (permissions), timestamp, owner, group, and size, you can +request that by also specifying the `\|\c +.B v\c +\|' modifier. + +If you do not specify any \c +.I files\c +\&, all files in the archive +are listed. + +If there is more than one file with the same name (say, `\|\c +.B fie\c +\|') in +an archive (say `\|\c +.B b.a\c +\|'), `\|\c +.B ar t b.a fie\c +\|' will list only the +first instance; to see them all, you must ask for a complete +listing\(em\&in our example, `\|\c +.B ar t b.a\c +\|'. + +.TP +.B x +\c +.I Extract\c +\& members (named \c +.I files\c +\&) from the archive. You can +use the `\|\c +.B v\c +\|' modifier with this operation, to request that +\c +.B ar\c +\& list each name as it extracts it. + +If you do not specify any \c +.I files\c +\&, all files in the archive +are extracted. + +.PP + +A number of modifiers (\c +.I mod\c +\&) may immediately follow the \c +.I p\c +\& +keyletter, to specify variations on an operation's behavior: + +.TP +.B a +Add new files \c +.I after\c +\& an existing member of the +archive. If you use the modifier \c +.B a\c +\&, the name of an existing archive +member must be present as the \c +.I membername\c +\& argument, before the +\c +.I archive\c +\& specification. + +.TP +.B b +Add new files \c +.I before\c +\& an existing member of the +archive. If you use the modifier \c +.B b\c +\&, the name of an existing archive +member must be present as the \c +.I membername\c +\& argument, before the +\c +.I archive\c +\& specification. (same as `\|\c +.B i\c +\|'). + +.TP +.B c +\c +.I Create\c +\& the archive. The specified \c +.I archive\c +\& is always +created if it didn't exist, when you request an update. But a warning is +issued unless you specify in advance that you expect to create it, by +using this modifier. + +.TP +.B f +Truncate names in the archive. +.B ar +will normally permit file names of any length. This will cause it to +create archives which are not compatible with the native +.B ar +program on some systems. If this is a concern, the +.B f +modifier may be used to truncate file names when putting them in the +archive. + +.TP +.B i +Insert new files \c +.I before\c +\& an existing member of the +archive. If you use the modifier \c +.B i\c +\&, the name of an existing archive +member must be present as the \c +.I membername\c +\& argument, before the +\c +.I archive\c +\& specification. (same as `\|\c +.B b\c +\|'). + +.TP +.B l +This modifier is accepted but not used. + +.TP +.B o +Preserve the \c +.I original\c +\& dates of members when extracting them. If +you do not specify this modifier, files extracted from the archive +will be stamped with the time of extraction. + +.TP +.B s +Write an object-file index into the archive, or update an existing one, +even if no other change is made to the archive. You may use this modifier +flag either with any operation, or alone. Running `\|\c +.B ar s\c +\|' on an +archive is equivalent to running `\|\c +.B ranlib\c +\|' on it. + +.TP +.B S +Do not generate an archive symbol table. This can speed up building a +large library in several steps. The resulting archive can not be used +with the linker. In order to build a symbol table, you must omit the +`\|\c +.B S\c +\|' modifier on the last execution of `\|\c +.B ar\c +\|', or you must run `\|\c +.B ranlib\c +\|' on the archive. + +.TP +.B u +Normally, \c +.B ar r\c +\&.\|.\|. inserts all files +listed into the archive. If you would like to insert \c +.I only\c +\& those +of the files you list that are newer than existing members of the same +names, use this modifier. The `\|\c +.B u\c +\|' modifier is allowed only for the +operation `\|\c +.B r\c +\|' (replace). In particular, the combination `\|\c +.B qu\c +\|' is +not allowed, since checking the timestamps would lose any speed +advantage from the operation `\|\c +.B q\c +\|'. + +.TP +.B v +This modifier requests the \c +.I verbose\c +\& version of an operation. Many +operations display additional information, such as filenames processed, +when the modifier `\|\c +.B v\c +\|' is appended. + +.TP +.B V +This modifier shows the version number of +.BR ar . + +.PP + +.SH "SEE ALSO" +.RB "`\|" binutils "\|'" +entry in +.B +info\c +\&; +.I +The GNU Binary Utilities\c +, Roland H.
