I'm working on a little script and I found another solution like the one I came up with use this line here:
for i in *; do
What exactly does the *; do/mean here? I'm used to seeing $ variables.
bash shell-script

for i in *; do
The * here is the filename globbing character that matches all (non-hidden) names in the current directory.
In each iteration of the loop, the variable i will take the value of each of the names matching * in turn.
The ; after the * (as in most other places) may be replaced by a newline:
for i in *
do

Per Confused about the behavior of asterisk in ls command
Asterisk expands before it gets to the [...your...] command
So you are passing all the files matching your pattern * to for
