To slow down your video, you have to use a multiplier greater than 1:

ffmpeg -i input.mkv -filter:v "setpts=2.0*PTS" output.mkv

For example, to double the speed of the video, you can use:

ffmpeg -i input.mkv -filter:v "setpts=0.5*PTS" output.mkv

pwd | clip - copy the present working directory to the clipboard.

grep -ro "pattern to find in files" "directory to recursively search" | grep -c "pattern to find in files"

This solution will count all occurrences even if there are multiple on one line.

-r recursively searches the directory

-o will "show only the part of a line matching PATTERN" 

this is what splits up multiple occurences on a single line and makes grep print each match on a new line;
