PROGRAM:

NAME


ar86 - Create, modify, and extract from archive file

SYNOPSIS


ar86 operation archive [file...]

ar86 positional-op member archive [file...]

DESCRIPTION


The ar86 program is used to create, examine and modify archive files produced by the
Dev86/ELKS toolchain.

OPTIONS


The ar86 command requires that the operation to be performed on the archive be specified
as the first option. If the operation is positional then the next option is the archive
member marking the position. This is followed by the archive file name and any list of
file names.

Operations
One of the following operations can be specified

d delete the listed files from the archive.

m move the named files. By default files are moved to the end of the archive unless a
positional modifier is present.

p print the contents of archive members to standard out. If a file list is included
only those members are printed. If the v modifier is present each file's contents
are preceeded by a new line, a line with the string member, a space character, the
member name, and two following newlines.

q quickly add the files to the end of the archive without checking to see if they
already exist in the archive. This operation will ignore any positional modifiers.
Creates the archive file if it does not exist.

r replace archive members with the files listed. If the file name is not present in
the archive it is added to the end of the archive (or to any explicitly specified
position). Creates the archive file if it does not exist.

t table; list the file names of archive members. If a file list is present only those
files that are present in the archive are listed. The v modifier prints member
attributes.

x extract the named files from the archive into the current directory. If no files
are specified all the archive members will be extracted.

Modifiers
The following modifiers may be used with the operations

o original time stamps from the archive are preserved for extracted files when
possible.

s symbol update; this option may be used by itself to force an update to the symbol
definition section of the archive (the __.SYMDEF member). If any files are
specified they will be replaced as if the r operation had been specified. If no
symbol definition section exists one is created. This option will also creates the
archive file if it does not exist.

u update files in the archive during a r (replace) operation. The files are added to
the archive in exactly the same manner as replace except that an existing archive
member will be retained (in its original position) if it has a modified more
recently than the file being added. Note that this modifier acts as if a r
operation has been specified (even it has not), and will actually override any
other previously specified operation.

v verbose; print additional diagnostic messages while processing the archive.

Positional Modifiers
The following modifiers specify where in the archive files are moved to or added. If any
of these modifiers are specified then the second option to ar86 must be the name of an
archive member.

a after; files are placed after the specified archive member.

b before; files are placed before the specified archive member.

i same as b.
