What could a user see if they were logged in?

[jasonlambert]

Hiya,

Im looking for a program or script that could show me a list of file and folders that a specified user could access if they were logged in.

Eg, out of all the files on the harddrive, what would user "X" be able to read?

Anyone know of a script/program that does this?

Thanks,

Jason

I don't think that there is a command that can do that, but, correct me if I'm wrong, shouldn't it be possible to do it something like this (running as the user to check):

#!/bin/sh

function checkdir
{
    for f in "$1"*; do
        if [ -d "$f" ]; then
            if [ -r "$f" -a -x "$f" ]; then
                checkdir "$f/"
            elif [ -r "$f" ]; then
                echo "$f"
            elif [ -x "$f" ]; then
                echo "half-warning: $f is executable, but not readable"
            fi
        fi
        if [ -f "$f" -a -r "$f" ]; then
            echo "$f"
        fi
    done
}

checkdir /
