Question

I got my computer today to do work on a bashscript called MF.sh..

wget somefile1
wget somefile2
wget somefile3

Ok. But somefiles familly like to change every minute, so I wrote this amazing piece of code to repeat the work every minute:

sleep 45
./MF.sh

I ended up killing zilllion process in htop manually.

What is the best practice here? What type of loop to use? Where to break? Using “i” like control variable is just a convention? How to use minutes time to control this?

EDIT (expanding question instead of answering it)

I tryed this

h=$(date +%R) 
for ($(date +%R) = $h)

     then

to catch when minute changes, but failed.

Answer 1

while loops while its command is true. true is always true.

while true
do ...
   ...
  if ...
  then
    break
  fi
   ...
done
