Its "best" PHP practices - +-1 in such big numbers - who really cares of that :)<br /><br />Thats why I don't like PHP, and there is much more - why I hate it :)<br /><br />P.S. PHP int min is of course: (-1 * PHP_INT_MAX ) - 1<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/517392339197915390-5782078895883960711?l=word-on-web.blogspot.com' alt='' /></div>Sergiohttp://www.blogger.com/profile/05571625985147202572noreply@blogger.com1tag:blogger.com,1999:blog-517392339197915390.post-34020404733962111402008-10-22T10:27:00.000-07:002008-12-03T12:45:59.987-08:00Occasionally I have to perform some operations in Linux shell.<br />MC helps a lot, but there are some commands I have to google for each time I need them.<br />So here I will have a storage of some shell commands.<br /><br /><span style="font-weight: bold;">File compression (Creating archives in linux)</span><br /><br /> Create tar archive<br /><span style="font-style: italic;">tar -cvf compr.tar dir</span><br /><br /> The same gzipped<br /><span style="font-style: italic;">tar -czvf compr.tgz dir</span><br /><br />from <a href="http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/getting-started-guide/s1-managing-compressing-archiving.html">red-hat site</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/517392339197915390-3402040473396211140?l=word-on-web.blogspot.com' alt='' /></div>Sergiohttp://www.blogger.com/profile/05571625985147202572noreply@blogger.com0tag:blogger.com,1999:blog-517392339197915390.post-85319667881407648092008-08-24T04:12:00.000-07:002008-08-24T04:57:13.444-07:00Hi there!<br /><br />Just started my first blog.<br />Actually I am in need of researching blogspot backend functionality, but who knows, maybe I'm a future super-blogger here ;)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/517392339197915390-8531966788140764809?l=word-on-web.blogspot.com' alt='' /></div>Sergiohttp://www.blogger.com/profile/05571625985147202572noreply@blogger.com0
