For counting the occurences of specific character in the file
I am issuing the command
grep -o 'character' filename | wc -w
It works in other shells but not in HP-UX as there is no option -o for grep.

I'm trying to count the number of 2 specific characters in a very large file. I'd like to avoid using gsub because its taking too long.
I was thinking something like:
awk '-F' { t += NF - 1 } END {print t}' infile > outfile
which isn't working
Any ideas would be great. (3 Replies)
