There’re times when I need to quickly search through occurrences of certain phrases in my PHP source files. Here is when I have to search for ‘giraffes’.
This is an example finding the word ‘giraffes’ in all PHP source files from the current directory recursively.
find . -name "*.php" -exec grep -i -H -n "giraffes" {} \;
This works for Ubuntu, CentOS and Mac OS X.
Oh you murderer, but let me assist:
kill -9 `ps -eo pid,args | grep "ssh " | grep -v "grep" | cut -c1-6`
This kills all ssh processes. I use this often to kill all my ssh tunnels. It works in Mac OS X Lion as well as Ubuntu/Debian Linux.
I assume you already have PEAR/PECL available. I am using the CentOS’s stock PHP. First you need to update your channels:
kahwee:~ kahwee$ sudo pear update-channels Updating channel "doc.php.net" Channel "doc.php.net" is up to date Updating channel "pear.php.net" Channel "pear.php.net" is up to date Updating channel "pecl.php.net" Channel "pecl.php.net" is up to date
PHP not sending emails? You need a mail transfer agent (MTA). If you’re in the Ubuntu platform, you can use postfix for this:
sudo apt-get install postfix
You can read on more information here.
Previously my Contact Form 7 WordPress plugin didn’t work, it works fine after I install and configured postfix. I can’t go through the specifics of the configuration with you since yours would probably differ. I selected “Internet Site” and press the return key (Enter) all the way selecting the default options. On doing so, Contact Form 7 starts to work already.
Should you need to configure postfix again, you can reconfigure too:
sudo dpkg-reconfigure postfix
Contact Form 7 uses WP_Mail which uses PHP’s mail() function. If you do need to troubleshoot, try sending emails with mail().
If you need additional configuration, you may need to update the following:
I did not have to configure anything more than postfix. I am using Ubuntu server, on nginx web server.

This is nerdy. Raw footage of a performance that “CS rapper” Monzy gave last summer outside Stanford University’s Computer Science building.
kill -9
kill -9 no more CPU time and your processes are mine. kill -9 ’cause it’s my time to shine.
You could try these unix commands if you’re really bored. It probably works on Ubuntu too.
% "How poorly would you rate the Unix (so-called) user interface?
Unmatched ".
% rm congressional-ethics
rm: congressional-ethics nonexistent
% ar m God
ar: God does not exist
% [Where is Jimmy Hoffa?
Missing ].
% ^How did the sex change^ operation go?
Modifier failed.
% If I had a ( for every $ Congress spent, what would I have?
Too many ('s.
%make love
Make: Don't know how to make love. Stop.
% sleep with me
bad character
% got a light?
No match.
% man: why did you get a divorce?
man:: Too many arguments.
% ^What is saccharine?
Bad substitute.
% \(-
(-: Command not found.
% sh
$ PATH=pretending! /usr/ucb/which sense
no sense in pretending
$ drink <bottle; opener
bottle: cannot open
opener: not found
$ mkdir matter; cat >matter
matter: cannot create
(via GNU.org)
My favorite is:
% man: why did you get a divorce? man:: Too many arguments.
