It works
The only change I made to your code was the ">" to "<" to look like this (val<=$1)

but the code prints the values of file1 as well as a new row

example:
Code:

which I don't want. In {print;exit} this is the part I don't understand on how to make it only print the data from file 2.

thanks

Never mind. removing the echo works like you say previously.

Final code:
Code:
while read line
do   
    awk -v val=$line '{if (val<=$1) {print;exit}}' file2
done < file1


Thanks

bootcdflopcp

BOOTCD(1)							   bootcd utils 							 BOOTCD(1)

NAME

       bootcdflopcp - copy changes made after booting from bootcd to floppy

SYNOPSIS

       bootcdflopcp [-v] [-d <device>]

DESCRIPTION

       bootcdflopcp  will  copy changes made in ram to the floppy disk.  bootcdflopcp will be available as soon as your system is running from cd.
       The floppy has to have a filesystem already. (See mke2fs or mformat).  If you have to boot from floppy, because your cd-drive or bios  does
       not  support  to  boot from cd a msdos filesystem is used to run syslinux.  When bootcdflopcp is called it searches for differences between
       RAM and CD.  For each different file, it checks if it is listed in the files ignore, remove or change on floppy. If it is listed in  change
       it  will  be  saved to change.tgz on floppy. If it is listed in remove the file will be removed from ram next boot time. If it is listed in
       ignore it will be ignored. If it is not listed at all you will be interactively asked what to do.

OPTIONS

       -v  The option "-v" (verbose) adds messages on running.

       -d <device>
	   Use another device instead of "/dev/fd0" to save changes.

FILES

       FLOPPY:/remove
	      If a file is listed here the file will be deleted from ram next boot time.

       FLOPPY:/change
	      If a file is listed here bootcdflopcp will save it in change.tgz.

       FLOPPY:/ignore
	      If a file is listed here bootcdflopcp will ignore changes to this file.

       FLOPPY:/change.tgz
	      Here all changed files are stored in gzipped tar format.
