|
|
Since version 2.0, multiple distinct actions can be specified in a single
|
|
invocation of GNU Stow. For example, to update an installation of Emacs from
|
|
version 21.3 to 21.4a you can now do the following:
|
|
|
|
<pre class="example"> stow -D emacs-21.3 -S emacs-21.4a
|
|
</pre>
|
|
<p class="noindent">which will replace emacs-21.3 with emacs-21.4a using a single invocation.
|
|
|
|
<p><a name="index-deferred-operation-34"></a>This is much faster and cleaner than performing two separate
|
|
invocations of stow, because redundant folding/unfolding operations
|
|
can be factored out. In addition, all the operations are calculated
|
|
and merged before being executed (see <a href="Deferred-Operation.html#Deferred-Operation">Deferred Operation</a>), so the
|
|
amount of of time in which GNU Emacs is unavailable is minimised.
|
|
|
|
<p>You can mix and match any number of actions, for example,
|
|
|
|
<pre class="example"> stow -S pkg1 pkg2 -D pkg3 pkg4 -S pkg5 -R pkg6
|
|
</pre>
|
|
<p class="noindent">will unstow pkg3, pkg4 and pkg6, then stow pkg1, pkg2, pkg5 and pkg6.
