# cat infile
sasasa  dwedwdw dewedwed        dwdqwd  ddwed   ddfwe

# od -c infile | grep -o "\t" | wc -l

Hi ygemici, don't you mean:

grep -o "\t" infile | wc -l
5

Actually I dont mean this..because we dont look the invisible chars in normal text with grep..

sed 's/\t/--TABHERE--/g' infile
sasasa--TABHERE--dwedwdw--TABHERE--dewedwed--TABHERE--dwdqwd--TABHERE--ddwed--TABHERE--ddfwe--TABHERE--
