Question

How can you check if the directory exists using a while loop in bash? In general, words what I want is while true if directory exists to do something

Sounds like you've got the gist. Have you looked at some basic bash syntax guides to see if you can turn your pseudocode into bash? — siride, Mar 27 '22 at 17:04

You can use the following construct to check if a folder (with name $dirname) exists:

[ -d $dirname ]

This will exit successfully if the folder exists, allowing for the following code:

[-d $dirname ] && echo "exists" || echo "does not exist"

or

if [ -d $dirname ]; then
    echo "exists"
fi
