PKG scripts – postflight, preflight, etc.

[pteeter]

For such scripts to work properly within the InstaDMG framework, one has to include the $3 argument when referring to the target installation volume, correct?

Thus far I’ve written all postflight/preflight scripts in /bin/sh.

A number of these preflight scripts do file removal for software updates. File removal for paths with tons of spaces in the full path.

Anyone got a best practice technique for prepending a $3 argument to a path with spaces in it?

$3″/path/to/filename with spaces in it”

I’ve been playing around with it but can’t seem to find a consistent solution.

#!/bin/sh
#
# Authored by:
# This script…
#
# Installer.app Environmental Variables
# $0 Script path
# $1 Package path
# $2 Default location
# $3 Target volume
#
echo variable 3 is “$3″/
echo Current path is `pwd`/
#
# set working directory. This is good to start with so you are working from the volume you are installing to.
cd “$3″/
#
# Start the script.
# basically put “$3” in front of all your absolute paths. The quotes “$3” will take care of a hard drive with spaces in the name.
