Just #@$% do it!

If you have an unreliable network feed and want to run something like rsync, scp, etc. without having to babysit it a simple function can be used to prefix a command. The function looks like this:



# Function to force a command to try until it works.

# Name means "JUST #@$% DO IT!"

JFDI () {

  COMMAND=$*

  while ! $COMMAND ; do echo "Retrying..." ; done

}

Using it is simplicity itself:



# command that can fail and annoy

rsync -avz /my/local/directory/ myuser@host:~/my/remote/directory/



# command that won't give up ever

JFDI rsync -avz /my/local/directory/ myuser@host:~/my/remote/directory/
