Counting the occurence of a word in a collection of files in Linux

Question

I am trying to find the word count of a specific word in a collection of documents, in Linux.

I have tried with grep and ack-grep in combination with wc but I can't seem to come up with a valid combination of pipes :)

Answer 1

Try the following:

grep -o "string" filename | wc -w

If you want all files in a directory, run the following script from that directory:

for file in *
    do let count=$count+`grep -o "wordyouaretryingtofind" $file | wc -w`
done
echo occurence $count times
