filter a data sheet for blank spaces
I have a datasheet with data organised in columns and seperated by tabs. I am trying to filter out only those rows where data are missing.
1 2 3 4
5 7 8
that is I am trying to retrieve the second row but in vain. If the columns were seperated by spaces I could have use d the class name [[:space:]] with grep to get the result.. is there a related class name for tab? or is there another method than grep to obtain the desired result..
