I want a script to execute the command:
ls -alst "dir with spaces"


The script looks like this :
#! /bin/bash

PARAMS_FOR_LS="-alst \"dir with spaces\""

echo $PARAMS_FOR_LS

ls $PARAMS_FOR_LS

   $PARAMS_FOR_LS is subject to word splitting.

   Try this instead:

PARAMS_FOR_LS=( -alst "dir with spaces" )
ls "address@hidden"
