tail -2 print the two last records of the file.
When you execute the command, there are 3 lines in the output ! Smilie

Execute the following command on your file :
Code:
od -cx R2_20060719.610.txt

Hi All,

Surprisingly my program is working fine now,
it's printing me all the lines of data file.

I did not do any thing to my data file and in script as well.
i thought of testing my luck once, suddenly it started working fine.

i dont understand what was the problem previously. Smilie
i dont understand how it's working now, with out doing anything in either of them(data and program) Smilie

full of confusions, but on the whole it's a nice experience to a fresher to Shell Scripting.

I thank all the people who responded me.
Thaking you all once again. Smilie

Regards,
Ravi Kumar Garlapati
