noglob is a keyword (a "precommand modifier", specifically) that
disables wildcard filename globbing:
% cd /tmp
% touch 'a*'
% touch 'ab'
% ls a*
% noglob ls a*
This trivial case isn't too useful, but consider wanting to copy
all .jpg files from your home directory on another machine to the
local machine via scp or rsync:
noglob scp kline at machine:*.jpg .
It's also amazingly handy in conjunction with the "find" command:
noglob find /usr/obj -name *.a
...so much so that I do:
alias find='noglob find'
...in my ZSH environment.
