<h3 class="section">1.2 Controlling <span class="command">ar</span> with a Script</h3>
|
||
|
|
||
|
<pre class="smallexample"> ar -M [ <<var>script</var> ]
|
||
|
</pre>
|
||
|
<p><a name="index-MRI-compatibility_002c-_0040command_007bar_007d-29"></a><a name="index-scripts_002c-_0040command_007bar_007d-30"></a>If you use the single command-line option <span class="samp">-M</span> with <span class="command">ar</span>, you
|
||
|
can control its operation with a rudimentary command language. This
|
||
|
form of <span class="command">ar</span> operates interactively if standard input is coming
|
||
|
directly from a terminal. During interactive use, <span class="command">ar</span> prompts for
|
||
|
input (the prompt is <span class="samp">AR ></span>), and continues executing even after
|
||
|
errors. If you redirect standard input to a script file, no prompts are
|
||
|
issued, and <span class="command">ar</span> abandons execution (with a nonzero exit code)
|
||
|
on any error.
|
||
|
|
||
|
<p>The <span class="command">ar</span> 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 <span class="sc">gnu</span> <span class="command">ar</span> for developers who already have scripts
|
||
|
written for the MRI “librarian” program.
|
||
|
|
||
|
<p>The syntax for the <span class="command">ar</span> command language is straightforward:
|
||
|
<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>a single command may appear on each line; it is the first word on the
|
||
|
line.
|
||
|
|
||
|
<li>empty lines are allowed, and have no effect.
|
||
|
|
||
|
<li>comments are allowed; text after either of the characters <span class="samp">*</span>
|
||
|
or <span class="samp">;</span> is ignored.
|
||
|
|
||
|
<li>Whenever you use a list of names as part of the argument to an <span class="command">ar</span>
|
||
|
command, you can separate the individual names with either commas or
|
||
|
blanks. Commas are shown in the explanations below, for clarity.
|
||
|
|
||
|
<li><span class="samp">+</span> is used as a line continuation character; if <span class="samp">+</span> appears
|
||
|
at the end of a line, the text on the following line is considered part
|
||
|
of the current command.
|
||
|
</ul>
|
||
|
|
||
|
<p>Here are the commands you can use in <span class="command">ar</span> scripts, or when using
|
||
|
<span class="command">ar</span> interactively. Three of them have special significance:
|
||
|
|
||
|
<p><code>OPEN</code> or <code>CREATE</code> specify a <dfn>current archive</dfn>, which is
|
||
|
a temporary file required for most of the other commands.
|
||
|
|
||
|
<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.
|
||
|
|
||
|
<dl>
|
||
|
<dt><code>ADDLIB </code><var>archive</var><dt><code>ADDLIB </code><var>archive</var><code> (</code><var>module</var><code>, </code><var>module</var><code>, ... </code><var>module</var><code>)</code><dd>Add all the contents of <var>archive</var> (or, if specified, each named
|
||
|
<var>module</var> from <var>archive</var>) to the current archive.
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>ADDMOD </code><var>member</var><code>, </code><var>member</var><code>, ... </code><var>member</var><dd><!-- FIXME! w/Replacement?? If so, like "ar r @var{archive} @var{names}" -->
|
||
|
<!-- else like "ar q..." -->
|
||
|
Add each named <var>member</var> as a module in the current archive.
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>CLEAR</code><dd>Discard the contents of the current archive, canceling the effect of
|
||
|
any operations since the last <code>SAVE</code>. May be executed (with no
|
||
|
effect) even if no current archive is specified.
|
||
|
|
||
|
<br><dt><code>CREATE </code><var>archive</var><dd>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>.
|
||
|
|
||
|
<br><dt><code>DELETE </code><var>module</var><code>, </code><var>module</var><code>, ... </code><var>module</var><dd>Delete each listed <var>module</var> from the current archive; equivalent to
|
||
|
<span class="samp">ar -d </span><var>archive</var> <var>module</var><span class="samp"> ... </span><var>module</var>.
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>DIRECTORY </code><var>archive</var><code> (</code><var>module</var><code>, ... </code><var>module</var><code>)</code><dt><code>DIRECTORY </code><var>archive</var><code> (</code><var>module</var><code>, ... </code><var>module</var><code>) </code><var>outputfile</var><dd>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 <span class="samp">ar -t </span><var>archive</var>
|
||
|
<var>module</var><span class="samp">...</span>. When verbose output is on, the listing is like
|
||
|
<span class="samp">ar -tv </span><var>archive</var> <var>module</var><span class="samp">...</span>.
|
||
|
|
||
|
<p>Output normally goes to the standard output stream; however, if you
|
||
|
specify <var>outputfile</var> as a final argument, <span class="command">ar</span> directs the
|
||
|
output to that file.
|
||
|
|
||
|
<br><dt><code>END</code><dd>Exit from <span class="command">ar</span>, 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.
|
||
|
|
||
|
<br><dt><code>EXTRACT </code><var>module</var><code>, </code><var>module</var><code>, ... </code><var>module</var><dd>Extract each named <var>module</var> from the current archive, writing them
|
||
|
into the current directory as separate files. Equivalent to <span class="samp">ar -x
|
||
|
</span><var>archive</var> <var>module</var><span class="samp">...</span>.
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>LIST</code><dd>Display full contents of the current archive, in “verbose” style
|
||
|
regardless of the state of <code>VERBOSE</code>. The effect is like <span class="samp">ar
|
||
|
tv </span><var>archive</var>. (This single command is a <span class="sc">gnu</span> <span class="command">ar</span>
|
||
|
enhancement, rather than present for MRI compatibility.)
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>OPEN </code><var>archive</var><dd>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>.
|
||
|
|
||
|
<br><dt><code>REPLACE </code><var>module</var><code>, </code><var>module</var><code>, ... </code><var>module</var><dd>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>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
|
||
|
|
||
|
<br><dt><code>VERBOSE</code><dd>Toggle an internal flag governing the output from <code>DIRECTORY</code>.
|
||
|
When the flag is on, <code>DIRECTORY</code> output matches output from
|
||
|
<span class="samp">ar -tv </span><small class="dots">...</small>.
|
||
|
|
||
|
<br><dt><code>SAVE</code><dd>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.
|
||
|
|
||
|
<p>Requires prior use of <code>OPEN</code> or <code>CREATE</code>.
