Find dead symbolic links

Find last modified files in a directory and its subdirectories
Goes through all files in the directory specified, uses `stat` to print out last modification time, then sorts numerically in reverse, then uses cut to remove the modified epoch timestamp and finally head to only output the last 10 modified files. Note that on a Mac `stat` won't work like this, you'll need to use either: $ find . -type f -print0 | xargs -0 stat -f '%m%t%Sm %12z %N' | sort -nr | cut -f2- | head or alternatively do a `brew install coreutils` and then replace `stat` with `gstat` in the original command.

Protip: git-annex loves these files

Count the number of characters in each line

Find inside files two different patterns in the same line and for matched files show number of matched lines
