Shell script to recover deleted files on Linux

RecoverFiles.sh

#!/bin/bash

if [[ ! $1 ]]; then
    echo -e "Usage:\n\n\t$0 'file name'"
    exit 1
fi

f=$(ls 2>/dev/null -l /proc/*/fd/* | fgrep "$1 (deleted" | awk '{print $9}')

if [[ $f ]]; then
    echo "fd $f found..."
    cp -v "$f" "$1"
else
    echo >&2 "No fd found..."
    exit 2
fi

The awk step is dangerous if there are any spaces in the path or filename, it will not give you the right filename (and it might exist..!)
Safer: sed -e 's/^[^>]* -> //' -e 's/ (deleted)$//'
And also the fgrep would be safer like: fgrep "$1 (deleted)$"
In theory, another problem would be existing opened files that end in ' (deleted)' which will show up...
