I work for a school district and it is the schools policy not to allow students to have executable files in their home directories. So I have been using ncpmount (netware server) on my linux box and executing the following commands

find /Path/to/students -type f | xargs file | grep executable

This works fine if there are no directories or filenames with spaces in them. If it finds a filename with a space in it, the command will freeze and I will have to break out of it. Not sure how I can preserve the spaces from what the find command outputs. I have tried putting quotes around everything under the sun but have had no luck with this.

How about something like:

find path-to-student-directories -type f -perm +111

I think that will locate all executable files (owner, group or world) regardless of the name.

Hope this helps.

Not so sure that would work on a Netware mounted volume but I will give it a try. Netware doesn't not have an execute in its file attributes.

I got it figured out. Here is the code if anyone wants to try it out.

# Filename: file.sh
# Date: March 9, 2004
# Purpose: Used to find executable files

clear

echo "Enter path name:"
read THEPATH
NAMEPART1=`echo $THEPATH | tr -d "/"`
NAMEPART2=`date +-run-%Y-%m-%d`
FILENAME=Exe_Violators_$NAMEPART1$NAMEPART2

echo "Now running the file command and grep  for "$THEPATH
# Time Stamping when the script started
date > $FILENAME

find $THEPATH -type f | sed -e 's/ /\\ /g' | xargs file | grep executable >> $FILENAME

# Time Stamping when the script ended
date >> $FILENAME

Now my only problem is if they have executables inside zip files. The file -z option does not seem to work to well.

Well I changed my script again. I needed to account for all special characters in the filenames. So the only thing I could think of was to use sed to put quotes around the filenames. But if a user puts a " in their filename the script will crap out because Xargs finds an unmatched quote. Anyone got any ideas.

# Filename: file.sh
# Date: March 9, 2004
# Purpose: Used to find executable files

clear

echo "Enter path name:"
read THEPATH
NAMEPART1=`echo $THEPATH | tr -d "/"`
NAMEPART2=`date +-run-%Y-%m-%d`
FILENAME=Exe_Violators_$NAMEPART1$NAMEPART2

echo "Now running the file command and grep  for "$THEPATH
# Time Stamping when the script started
date > $FILENAME

find $THEPATH -type f | sed -e 's/^/\"/' -e 's/$/\"/' | xargs file -z | grep executable >> $FILENAME

# Time Stamping when the script ended
date >> $FILENAME

Did you post this on Little Black Dog as well? 2FF =)

Anyways, why not just -

find /path/to/students -type f -exec chmod a-x {} \;

Or, better, mount their filesystem -o noexec

(Why play with them?)

Read my first post. I am Mounting a netware volume to my Linux box using ncpmount to run this script.

My problem has basically been solved with this script. You cannot name a filename in Windows with a quote in it so I do not have to worry about unmatched quote errors.
