1 inputfile

yes you are right but if not this code is very simple

"echo 1" is very simple, but also not correct Smilie

Reborg, Am I missing something? This does not seem to work.
Code:
echo "abaabcabc" | awk 'BEGIN {RS="abc" } END { print NR }'

It does, but your awk doesn't support muli-character RS. So yes, you are in a sense missing something, however behavior with multi-char RS is unspecified in POSIX. On Solaris you would use nawk, on HP-UX this probably will not work.

Solaris' 'nawk' does not support multi-char RS, You may try /usr/xpg4/bin/awk - I don't quite remember the details if it does support it.

Yes, you're right. I was thinking of FS handling, xpg4 awk does not support it either.

I guess in that case something like this would be needed(untested) for words as individual words using (n)awk which supports this for FS but not RS.
Code:
awk 'BEGIN{FS="(^|[[:blank:]]|[[:punct:]])word([[:blank:]]|[[:punct:]]|$)"} /./{ c+=NF-1} END {print c}' filename

To be honest I would not use awk for this myself, but as always there is more than one way of achieving a result.
