shell script pattern matching

Thanks for the reply. There is minor misktake in script i already sorted out. Now i have some other problem. which i am saving sql query result in variable. Let say

yahoo=$echo('select yahoo from table | mysql db --skip-column-names')
msn=$echo('select msn from table | mysql db --skip-column-names')

which results

yahoo=NULL
msn=NULL

now i want to compare the results that if yahoo and msn is NULL than don't do anything and if yahoo and msn variables contains email addresses than update another table with those values.

my if condition is not working. Please help me out to sort out this issue.

if [[ -n "$yahoo" && -n "$msn" ]]
then
echo "email found. NOT NULL"
else
echo "email are NULL"
fi

It display result "email are NULL"
while it should display "email found. NOT NULL"
because yahoo & msn both variables contains NULL. Please help me how to compare NULL.
Thanks in advance

CENTERIM(1)						      General Commands Manual						       CENTERIM(1)

NAME
centerim - a text mode based IM client for Linux, *BSD, Sun Solaris, MacOS X and possibly, other Unices. ICQ2000, Yahoo!, AIM TOC, IRC, MSN, Gadu-Gadu and Jabber protocols are now supported. Internal LiveJournal client and RSS reader are also provided. SYNOPSIS
centerim [ option ] ... DESCRIPTION
This manual page documents briefly the centerim command. centerim is a text mode menu- and window-driven IM interface. Currently ICQ2000, Yahoo!, AIM, IRC, MSN, Gadu-Gadu and Jabber protocols are supported. It allows you to send, receive, and forward messages, URLs, SMSes and, contacts, mass message send, search for users (including extended "whitepages search"), view users' details, maintain your contact list directly from the program (including non-icq contacts), view the messages history, register a new UIN and update your details, be informed on receiving email messages, automatically set away after the defined period of inactivity (on any console), and have your own ignore, visible and invisible lists. It can also associate events with sounds, add events to the outgoing queue from command line, define external event processing actions (like events auto-forwarding or elizatalk), has support for Hebrew and Arabic languages and allows to arrange contacts into groups. OPTIONS
-a, --ascii use ascii characters to draw lines and boxes -h, --help display command line usage -v, --version show the program version info -b, --basedir <directory> specify another base directory; useful for having several IM identities under the same UNIX account -B, --bind <hostname/ip> tells centerim to use the specified IP address for outgoing connections -B, --no-xtitles disable title changing in xterm or screen -o, --offline start with all protocols set offline The following commands are used to put events to the outgoing queue from the command line. If centerim is already running they're to be sent immediately, otherwise they will be sent as soon as you go on-line. -s, --send <event type> This parameter specifies the type of event you want to send. Currently only "msg", "url" and "sms" are supported. -p, --proto <protocol type> This one specifies to which IM network the destination contact belongs. Can be "icq", "yahoo", "aim", "irc", "jab", "msn", "gg" or "lj". -t, --to <nickname or UIN> With this one you specify nickname or UIN of the destination contact. For icq it's possible to specify 0 to send events to yourself. Only SMSes are known to be possible to be sent to oneself though. -n, --number <phone number> Using this parameter you can send SMSes to any mobile numbers through the ICQ network. The message text is read from the standard input, so use pipes in shell to pass it. For example, you can say "hi" to me through the ICQ network with the following command: $ echo "hi" | centerim -s msg -p icq -t 17502151 In case you want to send an URL, the URL itself and its description are separated with a newline character the following way: $ echo -e "http://thekonst.net/ My modest homepage." | centerim -s url -p icq -t 17502151 Please note, that all three parameters are required in order to queue an event. Finally, a small example of sending SMSes: $ echo "sms test" | centerim -s sms -n 1234567890 It's also possible to change your current status on a particular IM network with the following command line option. -S, --status <status letter> The argument parameter is a letter which indicates which status is to be set: o (Online), _ (Offline), a (Away), d (Don't disturb), n (N/A), c (Occupied), f (Free for chat), i (Invisible) -p or --proto <protocol name> Exactly the same like it was described for the previous command. Examples: $ centerim -S _ -p icq This will set the icq status to offline. In other words, it'll be disconnected immediately. $ centerim -S a -p yahoo And this command will switch your yahoo status to away. VERSION
