How to verify all user home directories are writable only by their owner
Hi, I'm currently working on my school assignment on how to verify that all user home directories are writable only by their owner on Solaris with VMware. But I'm not sure why my codes take a very long time to display the results. My friend says it's the `su - $i -c "ls -ld" 2> /dev/null | grep ^d | awk '{print $1}'` part that is causing the problem but his not sure what to do either. Can someone please help me? Thanks.
#!/usr/bin/bash
clear
echo " Verifying if user home directories are writable only by their owner"
echo
TEMPFILE=/permgrep.txt
TEMPFILE2=/namegrep.txt
accno=0
h=1
no=1
Ps=0
Fs=0
if [ ! -f ${TEMPFILE} ]
then
touch ${TEMPFILE}
fi
if [ ! -f ${TEMPFILE2} ]
then
touch ${TEMPFILE2}
fi
ACCOUNTS=`cat /etc/passwd | awk -F: '{print $1}'`
array=($ACCOUNTS)
for i in "${array[@]}"
do
let "accno += 1"
PRINTER=`su - $i -c "ls -ld" 2> /dev/null | grep ^d | awk '{print $1}'`
if [ -n "$PRINTER" ]
then
echo $PRINTER >> $TEMPFILE
echo $i >> $TEMPFILE2
fi
done
echo
for line in $(cat /permgrep.txt)
do
READTF2=`head -$h /namegrep.txt | tail -1`
if [ $line == 'drwxr-xr-x' ]
then
echo $no"-"$READTF2": PASS"
let "h += 1"
let "Ps += 1"
else
echo $no"-"$READTF2": FAIL"
let "h += 1"
let "Fs += 1"
fi
let "no += 1"
done
nohodi=`expr $accno - $Ps - $Fs`
echo " Total user accounts: "$accno
echo " Pass: "$Ps
echo " Fail: "$Fs
echo " no home directory : "$nohodi

createhomedir
createhomedir(1) BSD General Commands Manual createhomedir(1)
NAME
createhomedir -- create and populate home directories on the local computer.
SYNOPSIS
createhomedir [-scbalh] [-n directoryDomainName] [-u username]
DESCRIPTION
createhomedir provides several options for creating and populating home directories.
OPTIONS
-s creates home directories for server home paths only (default).
-c creates home directories for local home paths only.
-b creates home directories for both server and local home paths.
-a creates home directories for users defined in all directory domains of the server's search path.
-l creates home directories for users defined in the local directory domain.
-L causes the created home directory to be localized.
-n directoryDomainName
creates home directories for users defined in a specific directory domain in the server's search path.
-u username
creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a,
-l, and -n parameters when you use the -u parameter, -a is assumed.
-i reads username list from standard input and creates specified home directories. Each username should be on its own line.
-h usage help.
FILES
/usr/sbin/createhomedir location of tool
CAVEATS
When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible
home directories from being created. In this case, you may need to specify the usernames explicitly.
