Help with file search and destroy script

flippy · 07-24-2003, 02:02 PM

I've been working on a script for my boss so that he can automate going through ftp accounts and getting rid of "unnecessary" files like .exes and .mp3s. Some people are actually smart enough to rename files so i am using the file command to find the renamed files. I have not been able to get this up and running yet so I brought it to this GREAT

forum and hopefully someone will be able to pick it apart and help give me some idea of what i need to change. Any thoughts, help or suggestions would be appreciated.

#!/bin/bash

ls /home/*/ > temp.txt <--Not sure how to make this recursive

while [ -n $1 ]
do
loc = locate $1
f=file loc | tr -s " " " " | awk '/.*xec.*/ {print}' | cut --delimiter= " "
--fields=1 | tr -d ":"
if [ -n $f ]
then
echo Removing Illegal File $f
rm -rf $f <-- I know the the rf is a bit excessive
fi
done < temp.txt

rm -rf temp.txt <--Same here but i wanna make sure the file is gone

Code:

#!/bin/bash

find /home -type f > temp.txt

while [ -n $1 ]
do
  f=`file $1 | tr -s " " " " | awk '/.*xec.*/ {print}' | cut --delimiter " " --fields=1 | tr -d ":"`

  if [ -n $f ]
  then
    echo Removing Illegal File $f
    rm -f $f

    if [ -e "$f" ]
      echo "You weren't just being paranoid, $f is still here"
    fi

  fi

done < temp.txt

rm -f temp.txt

if [ -e temp.txt ]
  echo "You weren't just being paranoid, temp.txt is still here"
fi

Couldn't resist the paranoid bit... I'm guilty of it sometimes myself...

EDIT:
Stupid copy-and-paste errors! The first "paranoid" test was not programmed to look at the right file... DOH!

EDIT #2:
Stupid coder errors! That same test condition wasn't nested in the if block above like it was supposed to be... DOH!

thanks a lot for taking the time to look at it. yeah when it comes to making sure everything is cleared out I'm obviously a bit paranoid with that

find has an exec bit that you can pass the filenames to ...

Code:

#!/bin/sh

find /home -type f -name *.mp3 -print -exec rm -f {};
find /home -type f -name *.exe -print -exec rm -f {};

Yeah that'll be nice for the non-renamed ones but will it work for the files that have been renamed? like the file blob.exe changed to kittens.ppt?

(I like your alias, btw!)

AFA mp3's are concerned, if you've got a relatively speedy system, you could parse the files contents and search for mp3 specific information.. that way, you're not relying on the filename.. of course, this is much much slower than just simply searching for filenames... I assume that the same could be done for binary's as well..

that's about the only real way of which I can think to really get rid of all the things you don't want on the system.

deleting by filename is faster, for sure, but not effective for getting renamed files, especially if you're not sure to what they have been renamed.
