Possible problem with gawk on linux

[Mohit Parab]

> Dear All,
> 
>         The attached shell script creates a tempfile using gawk.  The problem 
> is as follows:
> 
>       1)  The script searches for the string 'parab' in the file mohit.out 
> and prints it to "tempfile"
>       2)  Before printing any output to tempfile it initialises it using the 
> system commanf >tempfile.
>       3)  During the first pass the gawk program creates the tempfile 
> properly as an ASCII text.  However, on the subsequent passes it creates a 
> "data" file.  The same can be checked using the file command of Linux.
