Empty Variable

I am trying to assign list of files that created that day to a variable 'filename'
filename=`ls -ltr |grep "Mar 6" | awk '{print$9}'`

If there are no files created that day, my script just hangs, i need help with some login here.

i am also trying to figure out a way to look for files that are created , say for ex: yesterday Mar 9. I am trying with

DATE=`date +%b`
DATE1=`date +%d`
tem="$DATE $DATE1"

If I give one more space it won't reconize date. Need help

Thanks,
Gundu

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME
bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression SYNOPSIS
bzgrep [ grep_options ] [ -e ] pattern filename... bzegrep [ egrep_options ] [ -e ] pattern filename... bzfgrep [ fgrep_options ] [ -e ] pattern filename... DESCRIPTION
Bzgrep is used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If bzgrep is invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, bzgrep uses it as the grep program to be invoked. For example: for sh: GREP=fgrep bzgrep string files for csh: (setenv GREP fgrep; bzgrep string files) AUTHOR
