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
$PARAMS_FOR_LS is subject to word splitting.
Try this instead:
PARAMS_FOR_LS=( -alst "dir with spaces" )
ls "${PARAMS_FOR_LS[@]}"
