Chapter 2. ar 7

• comments are allowed; text after either of the characters * or ; is ignored.

• Whenever you use a list of names as part of the argument to an ar command, you can separate the

individual names with either commas or blanks. Commas are shown in the explanations below, for

clarity.

• + is used as a line continuation character; if + appears at the end of a line, the text on the following

line is considered part of the current command.

Here are the commands you can use in ar scripts, or when using ar interactively. Three of them have

special signiﬁcance:

OPEN or CREATE specify a current archive, which is a temporary ﬁle required for most of the other

commands.

SAVE commits the changes so far speciﬁed by the script. Prior to SAVE, commands affect only the

temporary copy of the current archive.

ADDLIB archive

ADDLIB archive (module, module, ... module)

Add all the contents of archive (or, if speciﬁed, each named module from archive) to the

current archive.

Requires prior use of OPEN or CREATE.

ADDMOD member, member, ... member

Add each named member as a module in the current archive.

Requires prior use of OPEN or CREATE.

CLEAR

Discard the contents of the current archive, canceling the effect of any operations since the last

SAVE. May be executed (with no effect) even if no current archive is speciﬁed.

CREATE archive

Creates an archive, and makes it the current archive (required for many other commands). The

new archive is created with a temporary name; it is not actually saved as archive until you

use SAVE. You can overwrite existing archives; similarly, the contents of any existing ﬁle named

archive will not be destroyed until SAVE.

DELETE module, module, ... module

Delete each listed module from the current archive; equivalent to ar -d archive module ...

module.

Requires prior use of OPEN or CREATE.

DIRECTORY archive (module, ... module)

DIRECTORY archive (module, ... module) outputfile

List each named module present in archive. The separate command VERBOSE speciﬁes the

form of the output: when verbose output is off, output is like that of ar -t archive module....

When verbose output is on, the listing is like ar -tv archive module....

Output normally goes to the standard output stream; however, if you specify outputfile as a

ﬁnal argument, ar directs the output to that ﬁle.
