Need a Script help

George Abraham_3 — Thu, 15 Sep 2005 12:41:45 GMT

Hello Gurus,

I inherited a script that runs on all the unix servers. It checks for suid changes and sends a report.

Now on AIX servers i want to EXCLUDE the /proc directory.

So if the server is AIX exclude /Proc.

Can you please suggest what modification needs to be done?..Attached is the existing script

Any help will be welcome

regards
George

Change the find command. It starts with /:

find /

Change it to a list of all the mounted file systems except /Proc:

find /usr /etc /home /var

and so on.

I would like to check if OS=AIX then just exclude /proc.

thanks
George

You could do a condition handler that determines which set of directories to work against based on the output of a uname -a. You could use an if/then or possibly a case statement.

No time for coding examples right now. If I get time later, I can work on it. Someone else will probably have an example for you though.

OSTYPE=$(uname -s)

this will give you HPUX output (in capital letters) if executed on an hpux system. Run it on AIX machine and see what it generates and construct an "if" logic around the strings after your case statement block is executed.

in your find command lind before you |sort, yoyu could do a |grep -v '^/proc/' That would remove all files and directories under the /proc filesystem

I just remembered that I had an old, junky AIX box in one corner of mydata center and the command's output is AIX in capital letters as well.

use my above grep suggestion in conjunction with the other commanets about determining the OS = AIX

Hi George:

Use find()s '-prune'. Consider a case where you would want to find all files named "core*" [without being careful of what was returned :-)) ] and want to do that from the root directory, for every mountpoint there under, *except* /usr.

This syntax works on HP-UX or AIX so you can adapt it to your needs. In fact, since HP-UX doesn't have a /proc directory you can probably unconditionally factor this into your 'find' command regardless of the OS.

By example:

# find / -name usr -prune -o $ -type f -a -name "core*" -a -print $

...this returns all files named "core*" from all directories *except* 'usr'.

Regards!

...JRF...

George,

You could try the following.

NOTE: I don't have AIX machine. was not tested.

##################################################################################################
find_all_suid_FILES()
{
OSTYPE=`uname -s`
if [ ${OSTYPE} = "HP-UX" -o ${OSTYPE} = "AIX" ]
then
find / -type f -a $ -perm -u+s -o -perm -g+s $ -exec ls -dl {} \; | \
sort -k 3,3 -k 9,9 -k 4,4 > ${WORK_FILE} # Sort by user, group, and file
elif [ ${OSTYPE} = "AIX" ]
then
find / -type f -a $ -perm -u+s -o -perm -g+s $ -exec ls -dl {} \; | \
sort -k 3,3 -k 9,9 -k 4,4 | grep -v /proc > ${WORK_FILE} # Sort by user, group, and file
fi
}

Tested on AIX 5.2 with Junior's modification. Works good.

Just change this code as,

find_all_suid_FILES()
{
OSTYPE=`uname -s`
if [ ${OSTYPE} = "HP-UX"]
then
find / -type f -a $ -perm -u+s -o -perm -g+s $ -exec ls -dl {} \; | \
sort -k 3,3 -k 9,9 -k 4,4 > ${WORK_FILE} # Sort by user, group, and file
elif [ ${OSTYPE} = "AIX" ]
then
cd /
for fdir in `ls`
do
if [ $fdir != proc ]
then
find $fdir -type f -a $ -perm -u+s -o -perm -g+s $ -exec ls -dl {} \; | \
sort -k 3,3 -k 9,9 -k 4,4 | grep -v /proc > ${WORK_FILE} # Sort by user, group, and file
fi
done
fi
}

To skip /proc directory when OS is AIX.

hth.
