Abandoned files

AL_3001 — Thu, 29 Jan 2009 09:33:45 GMT

Hi,

We have a script to check for abandoned files on our HP-UX server. Attaching the script for reference.

Now, we are asked to assign the user and group as "root" for these files. We have abandoned files aroung 3000+ on some servers. Can someone provide a script to do this rather than doing it one file at a time.

Any input is really appreciated.

Thank You..

just add this to the end of the script

for file in $(cat /var/tmp/abandoned_files.txt)
do
echo "Changing Permission of file $file to root.\n"
chown root:root $file
done

Check this out
find / -local $ -nouser -o -nogroup $ -exec chown root:root {} \; 2>/dev/null |grep -v "total 0"

You absolutely don't want to use root:root for these files. Better to make up a dummy user. You could use bin:bin.

You need to change your find so you don't invoke ls. Or you need to add -d so ll on directories don't list the files under them:
awk '{print $9}' /var/tmp/abandoned_files.txt | xargs chown bin:bin

If lots of files, "for" may not work. No need for evil cat.

>Sagar: find / -local $ -nouser -o -nogroup $ -exec chown root:root {} \; 2>/dev/null |grep -v "total 0"

No need for that grep (ll output) and that stderr redirection. Also replace that \; with "+" for performance.

just realised after seeing Dennis' reply:

the for loop should be

for file in $(awk '{print $9}'/var/tmp/abandoned_files.txt)

or the other find commands suggested will work as well - although these will have to search the filesystem again.

Thanks for the reply dennis - do you know what the limit on a for loop is?

No need for a for-loop because you can put these files on chmod directly:
chmod bin:bin
$(awk '{print $9}' /var/tmp/abandoned_files.txt)

>do you know what the limit on a for loop is?

I thought it is at least 1 Mb.

Hi Dennis,

I have made a seperate script to assign the abandoned file ownership to bin:bin. However, I get the below error:
---------------------------------
# ./aban_chk.sh
Usage: chmod [-A] [-R] [ugoa]+-=[rwxXstugo][,...] file ...
./aban_chk.sh[2]: .cshrc: not found.
---------------------------------

Attaching the script in the .txt file.

Kindly assist.

Thanks..

Dennis/ Gurus,

One more question, few of the abandoned files seen in file abandoned_files.txt is attached.

My question is, how do i know the absolute path of a file say i.e SDBM_File.pm .

Kindly assist.

Thanks.

Hi,

having no absolute filename in your list, you can only guess.
You'll have to record the full pathname, when creating the list at first.
For example, change constructs like
cd /this/dir/name
find . -option ........
to
find /this/dir/name -option ...

"My question is, how do i know the absolute path of a file say i.e SDBM_File.pm "

since you started find in "/", I'll bet that's where you will find the file.

Hi Gurus,

How can I search files using a find coming with date syntax in the search.

For Eg:
-------------------------------------
-rw-r----- 1 root root 814 Jun 9 1997 .cshrc
-rw-r----- 1 root root 347 Jun 9 1997 .exrc
-rw-r----- 1 root root 341 Jun 9 1997 .login
-rw-r----- 1 root root 446 Jun 9 1997 .profile
-------------------------------------

Eg: In the /var/tmp/abandonedfiles.txt file i see the above 4 files with relative path. Can i search these files with the timestspa as Jun 9 19997 in my find command?

Assistance required.

Thank You..

Sorry, I didn't realize the forum split the two lines. When I saw it, I assumed you would figure it out.

>how do i know the absolute path of a file

As I mentioned, you are going to have to redo that find and use "-exec ls -l -d". Or just remove -exec.

Or you can ignore them since they come from the directory and you can rescan after you chown the files.

>OldSchool: since you started find in "/", I'll bet that's where you will find the file.

No, the files would start with "/".

>Can I search these files with the timestamps as Jun 9 1997 in my find command?

Why bother? These files are repeated with the absolute path:
grep "Jun.*9.*1997.*\.cshrc" /var/tmp/abandoned_files.txt
