Shell Programming and Scripting

I want to find a file say IIFT and check its size is zero or not. If its zero then I have to rename anothe file say WWFT , which is in another folder to WWFT$Todaysdate.

I tried below command:

Code:

cd dir2 (*File WWFT is in dir2)
 
find dir/ -type f -name 'IIFT*' -size 0 -exec mv WWFT WWFT$Todaydate \;

But its not working,please tell me why and how it should work?
Also, i have to mail this WWFT$Todaydate file in attachment.

Please guide me for the above task.

Thanks in advance.

Works fine for me, so I'm guessing you're not looking for files in the right places:

Code:

$ mkdir dir
$ cd dir
$ touch IIFTa
$ touch WWFT
$ TD=2011-11-11
$ find . -type f -name 'IIFT*' -size 0 -exec mv WWFT WWFT$TD \;
$ ls
IIFTz  WWFT2011-11-11
$

Note that yours excludes the current directory. I did find . and you did find dir/

If this file is buried several levels deep, you'll probably need find, but if it's always in the same place, there might be an easier way to do it in shell. What's your system, what's your shell?

Hi Corona,

Actually both these files IIFT and WWFT are in separate directories altogether i.e. IIFT is in dir1 and WWF is in dir2.
So I tried this command :

find dir1/ -type f -name 'IIFT*' -size 0 -exec mv dir2/WWFT dir2/WWFT$Todaydate \;

A problem here is though the above command finds the file IIFT* with 0 size, it does not rename the file WWFT. The find command's exit status is sucessfull, but when I looked for the file WWF$TD in dir2, i can find the previous WWFT file only i.e. it is not renamed.Whats going wrong here i need to find out as my script checks for this renamed file first and if it does not found it then only it moves ahead?
I am using HPUX ? I am not exactly aware of shell but when i did echo $SHELL it gave o/p "sh".

Don't cd into anything, then. Stay in the current directory and tell find to only look inside the dir you want. If all else fails, you can always give mv the absolute paths you want (/path/to/file instead of to/file)
