using loops while finding zeros
Thanxx for your replies but can someone suggest if i can use some loops so that i can echo when i encounter the zero's like:

if [ $file found zero]
then
echo "zeros found in bulk consecuively"
else
echo "everything is fine "
fi

Try:
Code:
if awk '{n=0;for(i=1;i<=NF;i++)if($i==0)n++}n>1{exit 1}' infile
then
  echo "everything is fine "
else
  echo "zeros found in bulk consecutively"
fi

thanks a gallon for your reply mate,
Could you also help if I want to find consecutive lines in which zeros are encountered like
0 54 55 22
0 22 55 32
0 65 97 789
0 48 99 66 41

Would that be "consecutive in the same column" in any of the columns?
