Ah yes, of course. Let me type out the larger picture so you can see how it's working.

The ls.txt is a cut listing of filenames (one filename per line).
As I'm opening each file, which happen to be all fixed-length csv files, I'm cutting the first field and the fifth field.

The following would be an example of two records (each line in each fixed-length csv file is a record with aproximately 32 fields). I have isolated the two fields for you.

Example fields (the forum deletes extra spaces so it would be easier I think if I describe it instead: FIELD1 is in columns 2-4 (a string of 3 letters), and the the second column aka FIELD5 can either be filled with a one digit number (1-9) or a single space (" ").

PHP Code:
while read FILENAME; do
    FIELD1=`cut -c2-5 $FILENAME`
    FIELD5=`cut -c68 $FILENAME`
    if [ $FIELD1 -eq "PBR" && $FIELD5 -eq " " ]; then
        $count++
    fi
done < ls.txt 
I'm kind of thinking that maybe it's not working because... if you try to use the "cut" command and it cuts a single space, maybe the shell doesn't assign anything to the variable?

yesterday

YESTERDAY(1)						      General Commands Manual						      YESTERDAY(1)

NAME

       yesterday - print file names from the dump

SYNOPSIS

       yesterday [ -c ] [ -date ] files ...

DESCRIPTION

       Yesterday prints the names of the files from the most recent dump.  Since dumps are done early in the morning, yesterday's files are really
       in today's dump.  For example, if today is March 17, 1992,

	      yesterday /adm/users

       prints

	      /n/dump/1992/0317/adm/users

       In fact, the implementation is to select the most recent dump in the current year, so the dump selected may not be from today.

       With option -c, yesterday copies the dump file to the current directory.

       The date option selects other day's dumps, with a format of 2, 4, 6, or 8 digits of the form dd, mmdd, yymmdd, or yyyymmdd.

       Yesterday does not guarantee that the string it prints represents an existing file.

EXAMPLES

       Back up to yesterday's MIPS binary of vc:

	      cd /mips/bin
	      yesterday -c vc

       Temporarily back up to March 1's MIPS C library to see if a program runs correctly when loaded with it:

	      bind `{yesterday -0301 /mips/lib/libc.a} /mips/lib/libc.a
	      rm v.out
	      mk
	      v.out

FILES

       /n/dump

SOURCE

       /rc/bin/yesterday
