Delete all files on a server with a particular filename


Dear All,

I wonder if you could help me please. I run 5GBFree.com a free hosting site. As you can imagine, it gets quite a few people signing up to abuse the service.

Recently I've found a LOT of people setting up sites with a particular script that floods forums and IRC chat rooms. The names of the files are as follows:

peindom1.php
peindom2.php
peindom3.php
peindom4.php

Is there a command I can run to remove files with these filenames ANYWHERE on the server (so basically, a command to go through all folders on the server and remove instances of that name).

If you could help I would really appreciate it, and I'm sure the people who run the forums and IRC rooms getting spammed would also be grateful to you.

Kind regards,
Rob

Hello and Welcome to LinuxQuestions,

Have a look at the man page of find, more in particular the use of -exec.
Code:
man find
Looking forward to your participation. Have fun with Linux.

Kind regards,

Eric

Are you looking to run a cron job to execute at specific intervals? Sounds more feasible to me so you don't use all of your resources just to scan your system. And you could use the find command to do the job.

Thankyou for your welcome, Eric.

I'm afraid I'm a REAL linux n00b! I typed 'man find' at the command prompt and LOTS of text appeared far too fast for me to read it!

I know I'm being cheeky but if you knew the command I need exactly I'd be really appreciative.

Kind regards,
Rob

You could use something like this:
Code:
find . -type f -name "peindom*" -exec rm -f {} \;
Cheers,

Josh

Thanks Josh. Ideally yes, a cron job would be fantastic but I'm no where near at the level I need to be at to set one up so I guess I'll just have to perform the job manually.

I ran the command above and got the following result:

5gbfree:~# find . -type f -name "peindom*" -exec rm -f {} \;
5gbfree:~#

So I don't know if that's done the job or not (I assume not as it's a find command and not delete?).

Thankyou again,
Rob

Hi,

You're welcome, no problem at all. Normally if you just type the command man find, you get the man page for that command presented and you can scroll through the document using the arrows, page up and down or search for a string by typing / followed by the string you want.

There's no shame at all in being a newbie, we all have to start somewhere and believe me nobody holds all the knowledge.

My buddy corp769 already provided an example but...
using the . means the find command will start looking at the directory you're in when executing the command. So either you change directory (cd) to where you want to run the search or you provide the path where to search instead of the . (dot).

Kind regards,

Eric

Note that the example I provided is scanning the directory you are currently in, you need to tell it where to scan from. And as far as setting up a cron job, read here: http://www.cyberciti.biz/faq/how-do-...-or-unix-oses/

Thankyou for that. I don't just want to find the files though, I want to remove them?

Hi,

That's what the
Code:
 -exec rm -f {} \;
part takes care of. find will pass any file that meets your criteria as parameter to the rm -f command and remove it.

Kind regards,

Eric

In the example I provided, the exec function of the command executes rm to remove the files found.

Cheers,

Josh

Hi Josh,

Thankyou - I'm afraid that command didn't work

I've manually checked a few spammers sites and the files are still there, dammit!

Cheers,
Rob

Hi,

Execute the command without the -exec part to see if any files are found. What's the path where those files normally get created? Do you have permissions as your user to that path and files?

Kind regards,

Eric
