Question No of columns in a variable
Hi

How do i find the number of columns in a variable

For example

I have a variable
Code:
 
abc=1-2-3-4-5-6-7

I should calculate the number of columns and the result should be 7.

Thanks in advance for the help.

And if you not like call awk, use builtin, then ex:
Code:
IFS="-"
fldvalues=( $abc )
flds=${#fldvalue[@]}
