I HAVE GIVEN ONLU 2 LINES IN FILE2

there are lacs of recorsd in file2.

i need to take 1st line in file1 and take that record in file2.

i have used grep command to fetch records from file2....but it is taking hours of time to fetch lacks of records

so i don't want to use grep. instaed how i can take the records from file2 by keeping file1 records.

Thanks in advance.


main goal is to optimise the time taken for greping.
i want to finish the entire fecthing within few minutes.

mv(1)							      General Commands Manual							     mv(1)

Name
       mv - move or rename files

Syntax
       mv [-i] [-f] [-] file1 file2

       mv [-i] [-f] [-] file... directory

Description
       The command moves (changes the name of) file1 to file2.

       If  file2  already  exists,  it is removed before file1 is moved.  If file2 has a mode which forbids writing, prints the mode and reads the
       standard input to obtain a line.  If the line begins with y, the move takes place.  If it does not, exits.  For further information, see

       In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.

       The command refuses to move a file onto itself.

Options
       -		   Interprets all following arguments as file names to allow file names starting with a minus.

       -f		   Force. This option overrides any mode restrictions or the -i switch.

       -i		   Interactive mode.  If a move is to supersede an existing file, the system prompts youw with the name of the	file  fol-
			   lowed  by  a question mark.	If you type a string that begins with y, the move occurs.  If you type any other response,
			   the move does not occur.

Restrictions
       If file1 and file2 lie on different file systems, must copy the file and delete the original.  In this case the owner name becomes that	of
       the copying process and any linking relationship with other files is lost.
