# This is a simple script to help get AppArmor working on different distros
# Generally these apparmor profiles target the latest LibreOffice

INST_ROOT=$1  #Where libreoffice program folder can be found
PROFILESFROM=$2  #Where the profile files are
INSTALLTO=$3  #Where should the apparmor profiles (For manual use should be /etc/apparmor.d)
RESTART=$4 #Should we restart apparmor using service?
CHECK=$5 #Check parsing of the new profile?

#Example uses:
#Ubuntu 16.04 with stock LibreOffice:
# sudo ./sysui/desktop/share/apparmor.sh /usr/lib/libreoffice/ sysui/desktop/apparmor/ /etc/apparmor.d/ true true

#Ubuntu 16.04, with built debs from LibreOffice git
# sudo ./sysui/desktop/share/apparmor.sh /opt/libreofficedev5.2/ sysui/desktop/apparmor/ /etc/apparmor.d/ true true

#Ubuntu 16.04, running from git!
# sudo ./sysui/desktop/share/apparmor.sh /mnt/store/git/libo/instdir/ sysui/desktop/apparmor/ /etc/apparmor.d/ true true

#Need to convert / to . for profile names
INST_ROOT_FORMAT=${INST_ROOT/\//}
INST_ROOT_FORMAT=${INST_ROOT_FORMAT////.}

#Need to escape / for sed
