Shell Programming and Scripting

HI all,
I am trying to grep few words in with file extension of srw. But grep is not giving any output. File has all the permisssions to read,write,execute.

If i try to search manually i can notice words whatever i want in the file.

my command is very simple

grep -i "word" *.srw

can u tell me any other limitations required for file size or any other things...

I copied file from windows to UNIX. after copy i observerd that "\377\376" added at the first line automatically. Is this creates any issue?

try the following sed command and see if it works

sed -n '/[wW]ord/p' *.srw

Hi thanhdat,

Its working fine. But I copied file from windows to UNIX. After copy, I observerd that "\377\376" added at the first line automatically. If i remove this, grep is working fine.
can any one tell why "\377\376" added at the begining for all the files....

Well, "^\377\376" means little endian in Windows Unicode format.
