Although the above will work in some implementations of awk, the standards say that the behavior when FS is an empty string is unspecified. A more portable way of writing the above would be:
Code:
awk '{	type[substr($1, 1, 1) == substr($1, 2, 1)]++ }
END {	print "Type1 = " type[1] ", Type2 = " type[0] }' file

which, when file contains the table shown in pst #1 in this thread, produces the output:
Code:
Type1 = 6, Type2 = 5

If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk.
