Shell script to read files and perform diff functions

devenix — Sun, 25 Jul 2010 07:08:10 +0000

Hi,

I wanted to extract files to read pdf files, they were around 100. So i tried to write a script to do the same.

while read line ; do unrar e “$line” ; done < myfile.txt

this will extract all the files in the same directory.

Deleting multiple tables from mysql database

devenix — Thu, 29 Apr 2010 02:13:10 +0000

Hi,

I was working on a project, had to delete multiple tables from a database.

I had 2 options , either delete individual tables using phpmyadmin or write a procedure for the same.

Since i am lazy, i did not liked the first option and since i am not a sql admin and didn’t have the time to learn and write a procedure to delete multiple tables , i couldn’t use the second option also.

So i created a php script to do the same, it worked for me. Hope it will work for you people also.

#######################

Deleting MySQL Tables

$dbhost = ‘localhost’;
$dbuser = ‘dnusername’;
$dbpass = ‘password’;

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die (‘Error connecting to mysql’);

$dbname = ‘databasename’;

/* query all tables and gets the tables with the matching string*/
$sql = “SHOW TABLES FROM $dbname like “somestring”;
if($result = mysql_query($sql)){
/* add table name to array */
while($row = mysql_fetch_row($result)){
$found_tables[]=$row[0];
}
}
else{
die(“Error, could not list tables. MySQL Error: ” . mysql_error());
}

foreach($found_tables as $table_name){
$sql = “DROP TABLE $dbname.$table_name”;
if($result = mysql_query($sql)){
echo “Success – table $table_name deleted.”;
}
else{
echo “Error deleting $table_name. MySQL Error: ” . mysql_error() . “”;
}
}
mysql_close($conn);

##############################

If anybody knows SQL command to do the same, do tell me, it will be useful and i don;t have to write such a big php script.

Raatris khel chale :- Beautiful Lyrics

devenix — Mon, 28 Dec 2009 18:37:34 +0000

Raatris khel chale, ya gudh chandanyancha
sampel na kadhi, ha khel sawalyancha

ha chandra na swayambhu, ravi tej vahato ha
grahanaat sawalyancha abhishap bhogato ha
pritis hoi sakshi, ha dut chandanyancha

aabhas sawali ha, asato khara prakash
je satya bhasati te, asati nitant bhas
hasataat sawalila, ha dosh aandhalyancha

sampel na kadhi, ha khel sawalyancha
Raatris khel chale, ya gudh chandanyancha
sampel na kadhi, ha khel sawalyancha

Installing 32 bit Adobe Reader 9 to a 64 bit Ubuntu 9.04

devenix — Thu, 05 Nov 2009 03:54:36 +0000

Hi,

M Back again.

I wanted to install the Abode acrobat on my ubuntu 9.04. Checked the site, it had only i386 version of Acrobat in the Deb format. It is really bad on their behalf.

So tried to install the i386 version on to my 64 bit machine and it displayed many errors.

So had to use a proper option with the dpkg command to install the 32 bit version.

dpkg -i --force-architecture AdbeRdr9.2-1_i386linux_enu.deb

And it installed properly.

I do not understand one thing ,linux community wants it to be more fexible than windows, then why differentiate between 32bit and 64bit binaries and create a problem for the users who want to install the 32 bit programs on the 64 bit machine.

They have to find a solution for this. Comman man can not use linux unless such problems are removed or handled properly.

Bye for now, I will be back again some day.

Nice song from Bandh Premache

Hya asha rimzhimi jhirmir paus dhara,
tan man phulaun jati

oo hya rimzhimi jhirmir paus dhara,
tan man phulaun jati

shwaas tuzha madhumass phulacha,
rang sukhacha haati

ha dhund gaar wara, ha kowala shahara
ujalun rang aahe, swachand pritiche

Chimb bhijalele, rup sajalele
barasuni aale rang pritiche.

kon jaage raat sari, antari sukhauni
sapt rangi pakharu he , endradhanu banu aale

laat hi , waadali, mohuni gaate
hi mithi ladaki mogara hote.

padasaad bhawananche, re bandh na kunache
daahi dishat gaane , be dhund pritiche
Chimb bhijalele, rup sajalele,
barasuni aale rang pritiche.

Kya hua tera vaada – Hum Kisi Se Kam Nahi

devenix — Tue, 21 Jul 2009 02:52:07 +0000

Kya hua tera vaada wo kasam wo iraada
kya hua tera vaada wo kasam wo iraada
bhoolega dil jis din tumhe wo din zindagi ka aakhri din hoga
kya hua tera vaada wo kasam wo iraada
bhoolega dil jis din tumhe wo din zindagi ka aakhri din hoga
kya hua tera vaada

yaad hai mujhko tune kaha tha tumse nahi roothenge kabhi
dil ki tarah se haath mile hain kaise bhala chhootenge kabhi
teri baahon mein beeti har shaam bewafaa ye bhi kya yaad nahi
kya hua tera vaada wo kasam wo iraada
bhoolega dil jis din tumhe wo din zindagi ka aakhri din hoga
kya hua tera vaada wo kasam wo iraada

o kehne waale mujhko farebi kaun farebi hai ye bata
wo jisne ghum liya pyaar ki khaatir ya jisne pyaar ko bech diya
nasha daulat ka aisa bhi kya ke tujhe kuchh bhi yaad nahi
kya hua tera vaada wo kasam wo iraada
bhoolega dil jis din tumhe wo din zindagi ka aakhri din hoga
kya hua tera vaada wo kasam

Likhe jo khat tujhe

devenix — Mon, 20 Jul 2009 21:54:52 +0000

One of my favorite songs from the movie Kanyadan.

Likhe jo khat tujhe
woh teri yaad mein
hazaaron rang ke
nazaare ban gaye

sawera jab huya
to phool ban gaye
jo raat aayi to
sitaare ban gaye

Koyi nagma kahin goonja
kahan dil mein
yeh tu aayi
kahin chatki kali koyi
main yeh samjha, tu sharmaayi
koyi khushboo kahin bikhri
laga yeh zulf lehraayi

Likhe jo khat tujhe…

Fiza rangeen, adaa rangeen
yeh ithlaana, yeh sharmaana
yeh angdhaayi, Yeh tanhaayi
yeh tarsa kar, chale jaana
bana de ga nahi kisko
jawaan jadoo yeh deewana

Likhe jo khat tujhe..

jahan tu hai, wahan main hoon
mere dil ki tu dhadhkan hai
musafir main tu manzil hai
main pyaasa hoon tu saawan hai
meri duniya yeh nazre hain
meri jannat yeh daaman hai

Likhe jo khat tujhe…
