# Update 2023-07-20:
# I've recently switched to installing `zsh` via `conda` which is a lot less hassle.
# I added it to start automatically in `tmux` with
# `set-option -g default-shell "~/miniconda3/envs/default/bin/zsh"`
#
# # Install Zsh on Sherlock
# Installs Zsh with Oh-My-Zsh without root privileges 
# on Stanford's Sherlock (https://sherlock.stanford.edu) for use in tmux

# Please note, the commands below will create unreadable files and should be 
# used for testing file size only. If you're looking for something that has
# lines in it, use /dev/urandom instead of /dev/zero. You'll then be able to
# read the number of lines in that file using `wc -l large-file.1mb.txt`

# Create a 1MB file
dd if=/dev/zero of=large-file-1mb.txt count=1024 bs=1024

# Create a 10MB file
dd if=/dev/zero of=large-file-10mb.txt count=1024 bs=10240
