grep command

Hi,
I need to grep two variables at the same time in shell programming.

Like today=Dec_16, and $1=5, how can I grep like this:
"$today_$1"?

Thanks in advance!

Your string makes DEC_165 - are you looking for DEC_15?
or DEC_165?

jim,
I am looking for "DEC_16_5".
I'd like $today is replaced by DEC_16 and $1 is replaced by 5.

try something like this

Code:

today="DEC_16"
num="5"

grep $today"_"$num  <filename>

You may want to replace $num with $1
