How to create shell script to handle commands like ls -l /somedir

Question

My script so far can handle the ls command and returns the files in the directory. Now i am trying to make it handle commands like ls -l /tmp . Any help?

My script so far:

#!/bin/bash
#set -x
clear

read -p "type a command:  " file
    read -r -a prog <<<"$file"
    IFS=: read -r -a paths <<<"$PATH"

        for val in "${prog[@]}" ; do 
        for path in "${paths[@]}"; do       

          [[ -x $path/$val ]] && "$path/$val"  "$@"         
        done
        done

Answer 1

Maybe like this:

#!/usr/bin/env bash
clear
IFS=: read -r -a paths <<<"$PATH"
read -p "type a command:  " cmd
read -d ' ' file <<<"$cmd"  #the first component of command
for path in "${paths[@]}"; do       
  [ -x "$path/$file" ] && eval "$path/$cmd"
done

This basically runs the inputted command for every possible PATH resolution.
