I am trying to do the following task:
write a shell script called changedir which
takes a directory name, a command name and (optionally) some additional arguments.
The script will then change into the directory indicated, and
executes the command indicated with the arguments provided. Here an example: $ sh changedir /etc ls -al
 This should change into the /etc directory and run the command ls -al. So far I have: #!/bin/sh
directory=$1; shift
command=$1; shift
args=$1; shift
cd $directory
$command
 If I run the above like sh changedir /etc ls it changes and lists the directory. But if I add arguments to the ls it does not work. What do I need to do to correct it?
