|
<p>If you use the single command-line option ‘<samp>-M</samp>’ with <code>ar</code>, you
|
|
can control its operation with a rudimentary command language. This
|
|
form of <code>ar</code> operates interactively if standard input is coming
|
|
directly from a terminal. During interactive use, <code>ar</code> prompts for
|
|
input (the prompt is ‘<samp>AR ></samp>’), and continues executing even after
|
|
errors. If you redirect standard input to a script file, no prompts are
|
|
issued, and <code>ar</code> abandons execution (with a nonzero exit code)
|
|
on any error.
|
|
</p>
|
|
<p>The <code>ar</code> command language is <em>not</em> designed to be equivalent
|
|
to the command-line options; in fact, it provides somewhat less control
|
|
over archives. The only purpose of the command language is to ease the
|
|
transition to <small>GNU</small> <code>ar</code> for developers who already have scripts
|
|
written for the MRI “librarian” program.
|
|
</p>
|
|
<p>The syntax for the <code>ar</code> command language is straightforward:
|
|
</p><ul>
|
|
<li> commands are recognized in upper or lower case; for example, <code>LIST</code>
|
|
is the same as <code>list</code>. In the following descriptions, commands are
|
|
shown in upper case for clarity.
|
|
|
|
</li><li> a single command may appear on each line; it is the first word on the
|
|
line.
|
|
|
|
</li><li> empty lines are allowed, and have no effect.
|
|
|
|
</li><li> comments are allowed; text after either of the characters ‘<samp>*</samp>’
|
|
or ‘<samp>;</samp>’ is ignored.
|
|
|
|
</li><li> Whenever you use a list of names as part of the argument to an <code>ar</code>
|
|
command, you can separate the individual names with either commas or
|
|
blanks. Commas are shown in the explanations below, for clarity.
|
|
|
|
</li><li> ‘<samp>+</samp>’ is used as a line continuation character; if ‘<samp>+</samp>’ appears
|
|
at the end of a line, the text on the following line is considered part
|
|
of the current command.
|
|
</li></ul>
|
|
|
|
<p>Here are the commands you can use in <code>ar</code> scripts, or when using
|
|
<code>ar</code> interactively. Three of them have special significance:
|
|
</p>
|
|
<p><code>OPEN</code> or <code>CREATE</code> specify a <em>current archive</em>, which is
|
|
a temporary file required for most of the other commands.
|
|
</p>
|
|
<p><code>SAVE</code> commits the changes so far specified by the script. Prior
|
|
to <code>SAVE</code>, commands affect only the temporary copy of the current
|
|
archive.

<dt><code>ADDLIB <var>archive</var> (<var>module</var>, <var>module</var>, … <var>module</var>)</code></dt>

<var>module</var> from <var>archive</var>) to the current archive.

any operations since the last <code>SAVE</code>. May be executed (with no
|
|
effect) even if no current archive is specified.
|

</p>
|

</dd>
|
|
<dt><code>CREATE <var>archive</var></code></dt>
|
|
<dd><p>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 <var>archive</var> until you use <code>SAVE</code>.
|
|
You can overwrite existing archives; similarly, the contents of any
|
|
existing file named <var>archive</var> will not be destroyed until <code>SAVE</code>.
|

</p>
|

</dd>

|
<dt><code>DELETE <var>module</var>, <var>module</var>, … <var>module</var></code></dt>
|
|
<dd><p>Delete each listed <var>module</var> from the current archive; equivalent to
|
|
‘<samp>ar -d <var>archive</var> <var>module</var> … <var>module</var></samp>’.
|
|

<dt><code>DIRECTORY <var>archive</var> (<var>module</var>, … <var>module</var>) <var>outputfile</var></code></dt>
|
|
<dd><p>List each named <var>module</var> present in <var>archive</var>. The separate
|
|
command <code>VERBOSE</code> specifies the form of the output: when verbose
|
|
output is off, output is like that of ‘<samp>ar -t <var>archive</var>
|
|
<var>module</var>…</samp>’. When verbose output is on, the listing is like
|
|
‘<samp>ar -tv <var>archive</var> <var>module</var>…</samp>’.
|
|
</p>
|
|
<p>Output normally goes to the standard output stream; however, if you
|
|
specify <var>outputfile</var> as a final argument, <code>ar</code> directs the
|
|
output to that file.
|
|
</p>
|
|
</dd>
|
|
<dt><code>END</code></dt>
|
|
<dd><p>Exit from <code>ar</code>, with a <code>0</code> exit code to indicate successful
|
|
completion. This command does not save the output file; if you have
|
|
changed the current archive since the last <code>SAVE</code> command, those
|
|
changes are lost.
|
|
</p>
|
|
</dd>
|
|
<dt><code>EXTRACT <var>module</var>, <var>module</var>, … <var>module</var></code></dt>
|
|
<dd><p>Extract each named <var>module</var> from the current archive, writing them
|
|
into the current directory as separate files. Equivalent to ‘<samp>ar -x
|
|
<var>archive</var> <var>module</var>…</samp>’.
|
|
</p>

<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.

</dd>
|
|
<dt><code>LIST</code></dt>
|
|
<dd><p>Display full contents of the current archive, in “verbose” style
|
|
regardless of the state of <code>VERBOSE</code>. The effect is like ‘<samp>ar
|
|
tv <var>archive</var></samp>’. (This single command is a <small>GNU</small> <code>ar</code>
|
|
enhancement, rather than present for MRI compatibility.)
|
|
</p>
|

<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
|
</p>
|
|
</dd>
|
|
<dt><code>OPEN <var>archive</var></code></dt>
|
|
<dd><p>Opens an existing archive for use as the current archive (required for
|
|
many other commands). Any changes as the result of subsequent commands
|
|
will not actually affect <var>archive</var> until you next use <code>SAVE</code>.
|

</p>

|

<dd><p>In the current archive, replace each existing <var>module</var> (named in
|
|
the <code>REPLACE</code> arguments) from files in the current working directory.
|
|
To execute this command without errors, both the file, and the module in
|
|
the current archive, must exist.

</p>
|

<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|

</p>

</dd>
|
|
<dt><code>VERBOSE</code></dt>
|
|
<dd><p>Toggle an internal flag governing the output from <code>DIRECTORY</code>.
|
|
When the flag is on, <code>DIRECTORY</code> output matches output from
|
|
‘<samp>ar -tv </samp>’….
|
|
</p>
|

</dd>

<dt><code>SAVE</code></dt>
|

<dd><p>Commit your changes to the current archive, and actually save it as a

file with the name specified in the last <code>CREATE</code> or <code>OPEN</code>
|

command.
