Is there a script (program) that can change the less file when the css compiled by it changes?

Question

css

For example, I compiled css from less.

less
.container-div{
padding: 20px;
    a{
        color: red;
    }
}

After compilation we get

сss
.container-div{
padding: 20px;
}
.container-div  a{
   color: red;
}

Now changed the padding of .container-div

сss
.container-div{
padding: 25px;
}
.container-div  a{
   color: red;
}

The script is run, finds this change and changes the less file

less
.container-div{
padding: 25px;
    a{
        color: red;
    }
}
