Pattern occurence in a file

How can we find the number of occurence of a specified pattern in a file?
This command would be a part of a shell script.

Nah. grep -c only counts number of lines on which a match occurs, not number of occurrences. So a line with <pattern>foofoo<pattern> would only count as one match with grep -c.

in awk..

awk -v s="foo" '{r+=gsub(s,s)}END{print r}' file1
