==== Remove unused disks paths on AIX ====

I use in my scripts a .env file to specify logpath and logname 

<cli prompt='>'>
root@nim /root/scripts > cat .env
# global variables for all scripts
export binpath=/root/scripts
export sn=`basename $0 | cut -d. -f1`
export HOSTNAME=`/usr/bin/hostname`
export logpath=/root/scripts/logs
export logname=$logpath/$sn.log
export configfile=$binpath/$sn.cfg
export destination="myemail@google.com"
export mail_undeliverable="myemail@google.com"
</cli>

<cli prompt='>'>
root@nim /root/scripts > cat ./remove_paths.sh
</cli>
