Shell Programming and Scripting

hi all,
am trying to 'grep' some text from a log file and use the 'cut' command to read from that line i just grep'ed to extract date/time and response times.

code sniplet i am using is :

grep -i 'text to grep' Out.log |
while read LINE;
do
mydate=$LINE | cut -f1 -d] | cut -f2 -d[ | cut -f1 -dN;
res=$LINE | cut -f2 -d] | cut -f2 -d[;

printf "%-16s %s\n" $mydate $res
done;


the output i want printed to the terminal in the following columns :

date time response


unfortunately this is printing empty values to the terminal.

the cut command i am using works since i echo'ed the output to the terminal. i think the problem is using printf to print since i am new to printf.

any suggestions on what could be wrong ??

thanks in advance,
Cesar.
