apologies

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?

mb_strcut - Get part of string

SYNOPSIS
string mb_strcut (string $str, int $start, [int $length = NULL], [string $encoding = mb_internal_encoding()]) DESCRIPTION
mb_strcut(3) extracts a substring from a string similarly to mb_substr(3), but operates on bytes instead of characters. If the cut position happens to be between two bytes of a multi-byte character, the cut is performed starting from the first byte of that character. This is also the difference to the substr(3) function, which would simply cut the string between the bytes and thus result in a malformed byte sequence. PARAMETERS
o $str - The string being cut. o $start - Starting position in bytes. o $length - Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string. o $encoding -The $encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used. RETURN VALUES
mb_strcut(3) returns the portion of $str specified by the $start and $length parameters. SEE ALSO
mb_substr(3), mb_internal_encoding(3). PHP Documentation Group MB_STRCUT(3)
