Edited my post while you were answering I guess. I didn't notice the 4th field 1st, because : b : without a blanks gives Smilie

can it reference to a variable?

example like
teststring= "wsd:ggs:ttj:sss"

how can i print out '4', separate the string with deliminter ':'

Code:
IFS=: set -- $teststring
echo $#

This will clobber $1, $*, etc.

Or you can do echo "$teststring" | awk -F: '{print NF}' (assuming $teststring doesn't contain stuff which confuses echo).
