Script to Automate Multi-User Development Permissions In Linux: Part II

As discussed in the previous entry a few moments ago:

While deploying a large virtual server for a client, one of the obstacles they had faced with their previous setup was multi-user permissions with regard to everyone modifying files and directories with their own FTP and/or SSH accounts. Unfortunately, for reasons that won’t be divulged here (quite frankly because I don’t know), and even after I suggested alternatives such as updating policies and standard operating procedures, the client opted to continue using previous methods, but still wanted a resolution to issues they faced in their multi-developer environment.

The following simple Bash script is called directly via a cron job every fifteen minutes:


#!/bin/bash

mode='4771';

# The directory in which "multiUserPermissionsFix" resides.
dir='/danbrown/scripts/';

if ( test "`whoami`" != 'root' ); then
echo "$0 MUST be run as root!";
exit -1;
fi;

if ( test "$1" == "" ); then
echo "You must specify the base directory.";
exit -1;
fi;

if ( test "$2" == "" ); then
echo "You must specify the group ownership to set.";
exit -1;
fi;

if [ -d "$1" ]; then

echo -n "Verifying ownership and group ownership of all files.... ";
chown -R $2:$2 $1;
echo "Done.";

cd $1;

echo -n "Resetting permissions now.... ";
find . -type d -exec chmod $mode '{}' \;
# for i in `find . -type d`; do
# chmod $mode $i;
# done;
echo "Done.";

echo -n "Verifying ownership requirements.... ";
find . -type d -exec chmod o+s '{}' \;
# for i in `find . -type d`; do
# chmod o+s $i;
# done;
echo "Good.";

echo -n "Verifying group requirements.... ";
find . -type d -exec chmod g+s '{}' \;
# for i in `find . -type d`; do
# chmod g+s $i >> /dev/null 2>&1
# done;
echo "Good.";

if [ "$?" != "0" ]; then
echo "That group does not exist!";
exit -1;
fi;

echo -n "Fixing bad permissions.... ";
$dir/multiUserPermissionsFix $1;
echo "Done.";

echo "Task Complete.";

exit 0;

else

echo "That directory doesn't exist!";
exit -1;

fi;
