Files are named in the archive by their last file name component, so if a file referenced by a path containing a "/" is archived, it will be named by the last component of the path. Similarly when matching paths listed on the command line against file names stored in the archive, only the last component of the path will be compared.
The normal use of ar is for the creation and maintenance of libraries suitable for use with the link editor ld(1), although it is not restricted to this purpose. The ar utility can create and manage an archive symbol table (see ar(5)) used to speed up link editing operations. If a symbol table is present in an archive, it will be kept up-to-date by subsequent operations on the archive.
The ranlib utility is used to add an archive symbol table to an existing archive.

Each input line contains a single command. Words in an input line are separated by whitespace characters. The first word of the line is the command, the remaining words are the arguments to the command. The command word may be specified in either case. Arguments may be separated by commas or blanks.
Empty lines are allowed and are ignored. Long lines are continued by ending them with the "+" character.
The "*" and "amp;;" characters start a comment. Comments extend till the end of the line.
When executing an MRI librarian script the ar utility works on a temporary copy of an archive. Changes to the copy are made permanent using the save command.
Commands understood by the ar utility are:
addlib archive | addlib archive (member [, member ]...) | |
Add the contents of the archive named by argument archive to the current archive. If specific members are named using the arguments member, then those members are added to the current archive. If no members are specified, the entire contents of the archive are added to the current archive. | |
addmod member [, member ]... | |
Add the files named by arguments member to the current archive. | |
clear | Discard all the contents of the current archive. |
create archive | |
Create a new archive named by the argument archive, and makes it the current archive. If the named archive already exists, it will be overwritten when the save command is issued. | |
delete module [, member ]... | |
Delete the modules named by the arguments member from the current archive. | |
directory archive (member [, member ]... )[outputfile] | |
List each named module in the archive. The format of the output depends on the verbosity setting set using the verbose command. Output is sent to standard output, or to the file specified by argument outputfile. | |
end | Exit successfully from the ar utility. Any unsaved changes to the current archive will be discarded. |
extract member [, member ]... | |
Extract the members named by the arguments member from the current archive. | |
list | Display the contents of the current archive in verbose style. |
open archive | |
Open the archive named by argument archive and make it the current archive. | |
replace member [, member ]... | |
Replace named members in the current archive with the files specified by arguments member. The files must be present in the current directory and the named modules must already exist in the current archive. | |
save | Commit all changes to the current archive. |
verbose | |
Toggle the verbosity of the directory command. | |
ar -rc ex.a ex1.o ex2.o ex3.o
To add an archive symbol table to an existing archive ex.a, use:
ar -s ex.a
To delete file ex1.o from archive ex.a, use:
To verbosely list the contents of archive ex.a, use:
To create a new archive ex.a containing the files ex1.o, and ex2.o, using MRI librarian commands, use the following script:
create ex.a * specify the output archive addmod ex1.o ex2.o * add modules save * save pending changes end * exit the utility
