Shell Programming and Scripting

hi all
Anybody have an idea to write the script to get the file size and sends an email when file size increse more than 10mb. thanks

Code:

/bin/find /path/tofile -name filename.whatever  -size +10485760c > ./big.dat
if [[ -s ./big.dat ]] ; then
     big.dat > /usr/bin/mailx -s 'file too big '  usename@foo.com
fi

You have to enter this into cron to run, say, every five minutes. If you want it checking constantly.

Thanks for your reply..

/bin/find /path/tofile -name filename.whatever -size +10485760c > ./big.dat

what I'm looking for is, as i said i have serveral files (*.txt) under the /var/opt/abc. if any of the file increased to more than 1mb, then i wanna send a mail with increased file name and size. Thanks once again.

Yes,
/path/tofile => /var/opt/abc
filename.whatever => "*.txt"

Thanks for your reply.

I just tried with the script which you give me and it did work with some changes. I modified the script like below

find -name core.* -size +10485760c > ./big.txt
#if [[ -s ./big.txt ]] ; then
#big.txt > /usr/bin/mailx -s 'file too big ' abc@xyz.com

this works but I want to see file size too like this..
-rw------- 1 root root 254517248 Aug 4 21:36 core.2909 and this line i wanna send as a mail.

when I tried with this...

/bin/find /path/tofile -name filename.whatever -size +10485760c > ./big.dat It says couldn't find the /bin/find.

Thanks for your help.

try this....

ls -lrt|awk '$5 > 10485760 {print}' > ./big.txt
if [[ -s ./big.txt ]] ; then
/usr/bin/mailx -s 'file too big ' abc@xyz.com < big.txt
