Hi All

I'm stuck on something and not sure what the problem is. This should be basic stuff but I'm not getting it to work.

All I want to do is run a small shell script against a file to test if the numbers match up. If they do, print PASS or if not FAIL.

The file I want to run against contains info like this:

Code:
2293595,2293595
2293596,2293596
2293597,2293597
2293598,2293598

No special characters that I can see and no whitespace on end etc.

The script:
Code:
for N in `cat $1 | awk -F, '{print $1}' `
 do
  N2=`cat $1 | grep "$N" | awk -F, '{print $2}'`
  ## This section added to try debug issue
  echo "$N" | wc
  echo "$N."
  echo "$N2" | wc
  echo "$N2."
 if [ "$N1" = "$N2" ]
  then
   echo "PASS"
  else
 echo " FAIL"
 fi
done

This is sample output from that when run against the file:

Code:
      1       1       8
2293595.
      1       1       9
.293595
 FAIL
      1       1       8
2293596.
      1       1       9
.293596
 FAIL
      1       1       8
2293597.
      1       1       9
.293597

So something is wrong on N2 .. its putting a value after the "." I'm using to test. It's also dropping a character.

Any ideas what the issue might be or a way around this?

Thanks in advance.
 
Never mind. Sorted it!! Ran dos2unix against my data file and that sorted everything. That's what happens when you use Windows - pah!
 
you mean Win-doze :-;
i am going to give you a star just for following up with the answer to your own problem ( so many don't bother) & highlighting an easily overlooked cause of trouble


I do not Have A.D.D. im just easily, Hey look a Squirrel!
 
Anyway, why not simply this ?
Code:
awk -F, '{sub(/\r$/,"");if($1!=$2){rc=1;exit}}END{print rc ? "FAIL" : "PASS"}' $1

Hope This Helps, PH.

another thing you may want to check:

[tt]
for N in `cat $1 | awk -F, '{print $1}' `
# variable is called N
do
N2=`cat $1 | grep "$N" | awk -F, '{print $2}'`
## This section added to try debug issue
echo "$N" | wc
echo "$N."
echo "$N2" | wc
echo "$N2."
if [ "$N1" = "$N2" ]
# and here you use N1, which is never initialized ???
then
echo "PASS"
else
echo " FAIL"
fi
done
[/tt]

HTH,
