The wget command can be used to obtain files from websites.
It can be notably faster to use wget than to download things like programs
or scripts and then upload them onto a cluster or workstation.
wget "https://raw.githubusercontent.com/emleddin/research-scripts/main/MD-Setup/Langevin/miller-NPT/eq1.mdin"
While you can use wget without quotes around the site/FTP location, it is
not often recommended because many web links contain characters that make the
Terminal panic.
Note: If you do not have Internet access (this will
typically become evident if you have issues trying to update certain programs),
wget will not work.
