How to grep a particular pattern using a variable

Hi all,

I am searching for the files with a pattern which is stored in a variable.
eg:
the day is taken from the date format into a variable "day"
I am trying to search with the pattern in that variable.

ls -ltr | grep "$day"

I am not getting the filtered output.

Please help me in how to search for the pattern which is in a variable.

Thanks,
ladtony

this should work.

try echoing the contents of day
Code:
echo $day

that should give an idea on whats going wrong

I didn't mean to dump the actual source file as such

sample output
