bash - Count multiple occurrences of some text for each file under a directory -

i trying count multiple occurrences of text each file under directory. following script close want not count multiple occurrences on same line:

grep -rc 'blah' /some/path --include \*.txt 

for example given 2 files:

foo.txt blah, hey blah more text  bar.txt blah 

the above script produces:

foo.txt:1 bar.txt:1 

but output looking is*:

foo.txt:2 bar.txt:1 

i know total number of occurrences can found in 1 file using grep , piping results word count:

grep -oh 'blah' foo.txt|wc -l 

how multiple files achieve output in example* above?

update

the best solution come follows:

find /some/path -name '*.txt'|awk '{print "echo -n '\''"      $0 "\: '\'' && grep -oh '\''blah'\'' " $0 "|wc -l"}'|bash 

grep -o prints each match on new line - count em up

dir=$1 grep -hor --include '*.txt' 'blah' $dir| uniq -c| # output after uniq #      3 dir/f0.txt:blah #      2 dir/f1.txt:blah awk '{file=gensub(/^.+\/|:.+/, "", "g", $2); print file ":" $1}'
