# This stuff was tested on zsh. It should work on bash but won't work on tcsh for sure!
# Dumb way to sort du output by size and only list up to the 50 top dirs that we can access
# |& is used to pipe stderr to the next command
#
du -k |& grep -v "Permission denied" | sort -nr | cut -f2 | head -n 50 | xargs du -sh |& grep -v "Permission denied" |& grep -v "No such" |& grep -v "Operation not"
# Compute the percentage of something
# 710 here is final expected number of files, we use `ls | wc -l` to get the current num of files
# then we pipe it into bc to do the math, then print to the console and save to file at the same time using tee

vvzen / find_centroid_of_clusters.cpp
Last active September 12, 2020 21:14
VEX code for finding centroids of clusters made with Houdini cluster node
// The cluster node in houdini creates 2 groups:
// attributepoints and clusterpoints
// but I need an attribute to store, for each cluster, the centroid
// So what I've come up is to...
// 1. Create an attribute on each point, called centroid
// and formatted like this: "{index_of_the_point}_{index_of_the_cluster}"
// See set_centroid_attribute.cpp
// 2. Use it so that each point will loop in all other points
