Displaying directory sizes (e.g. .git, node_modules, etc)

dir_sizes.sh

function dir_sizes() {
  find $1 -type d -name $2 -prune | while read line; do du -sh $line; done
}

alias ds=dir_sizes   # ds {start_dir} {name_pattern}

# e.g. list node_modules sizes recursively
# ds . node_modules
#
# output:
# 584k   ./project1/node_modules
# 211k   ./project2/node_modules
