Suppose you want to make sure that access to the file "important" is serialised, i.e., no more than one program or shell script should be allowed to access it. For simplicity's sake, let's suppose that it is a shell script. In this case you could solve it like this:<br />
<br />
<pre><br />
...<br />
lockfile important.lock<br />
...<br />
access_"important"_to_your_hearts_content<br />
...<br />
rm -f important.lock<br />
</pre><br />
<br />
Install part of procmail:<br />
apt install procmail</div>Kenneth
