NAMEiar - archive and library maintainer
SYNOPSISiar key [ posname ] afile [ file ... ]
DESCRIPTION
Iar maintains groups of files combined into a single archive file,
afile. The main use of iar is to create and update library files for
the loaders 2l(10.1), etc. It can be used, though, for any similar
purpose.
Key is one character from the set drqtpmx, optionally concatenated with
one or more of vuaibclo. The files are constituents of the archive
afile. The meanings of the key characters are:
d Delete files from the archive file.
r Replace files in the archive file, or add them if missing.
Optional modifiers are
u Replace only files with modified dates later than that of
the archive.
a Place new files after posname in the archive rather than
at the end.
b or i Place new files before posname in the archive.
q Quick. Append files to the end of the archive without checking
for duplicates. Avoids quadratic behavior in
t List a table of contents of the archive. If names are given,
only those files are listed.
p Print the named files in the archive.
m Move the named files to the end or elsewhere, specified as with
o Preserve the access and modification times of files extracted
with the x command.
x Extract the named files. If no names are given, all files in
the archive are extracted. In neither case does x alter the ar‐
chive file.
v Verbose. Give a file-by-file description of the making of a new
archive file from the old archive and the constituent files.
With p, precede each file with a name. With t, give a long
listing of all information about the files, somewhat like a
listing by ls(1), showing
mode uid/gid size date name
c Create. Normally iar will create a new archive when afile does
not exist, and give a warning. Option c discards any old con‐
tents and suppresses the warning.
l Local. Normally iar places its temporary files in the directory
/tmp. This option causes them to be placed in the local direc‐
tory.
When a d, r, or m key is specified and all members of the archive are
valid object files for the same architecture, iar inserts a table of
contents, required by the loaders, at the front of the library. The
table of contents is rebuilt whenever the archive is modified, except
when the q key is specified or when the table of contents is explicitly
moved or deleted.
EXAMPLEiar cr lib.a *.v
Replace the contents of library with the object files in the
current directory.

BUGS
If the same file is mentioned twice in an argument list, it may be put
in the archive twice.
The file format used by this command is taken from UNIX, and makes some
invalid assumptions, for instance that user IDs are numeric.
